Custom Resolution Tool for Intel Graphics Easier Overscan Correction

DTD Calculator:
Clever Technology Making Custom Resolutions for Intel Graphics Easier

For those of you who have or are considering Intel integrated graphics solutions, you may or may not have observed that the standard tool for coping with custom resolutions-- EnTech's Powerstrip-- doesn't work properly with Intel graphics. Why that is is somewhat irrelevant to the discussion here. The important thing is that the Powerstrip situation doesn't appear to be changing anytime soon, and Intel hasn't published any information which implies there is something in the works at their end.

This situation comes at a very annoying time, since the Intel Graphics are becoming a better and better solution for a home theater PC with new DVI and HDMI solutions and better video processing capabilities.

Intel graphics have the capability of specifying custom timings using the VESA standard Detailed Timing Descriptor (DTD), but it's a register hack and the method is cryptic (see http://softwarecommunity.intel.com/W...aphics/239.htm for more than you've ever wanted to know on the matter). A better method is desirable: something graphical as Powerstrip provides, and as Nvidia and ATI provide as well. Not sure it will ever be easy to understand, but it should at least be easier to get the work done. That's where a freeware program called DTDCalculator (developed out of the kindness of their heart by the nice guys at Clever Technologies in the UK) comes in.

DTDCalculator's primary goal is to take a very manual, math-intensive process and make it human. And I think it succeeds.

1) You can download the software installer from my personal site at
http://members.cox.net/archibael/setupdtd100.exe
Clever Technologies is also hosting:
http://www.clevertec.co.uk/productsfree.htm#dtdcalc

2) Install the SW and start it up. Note that you need to be running the application with Administrative privileges in order to write to the registry under Vista with UAC enabled.

3) Get one or more DTDs from some source and write them to the registry

There are several starting places:

a) One of the most accurate (for your particular monitor) would be by grabbing the EDID data from the Intel Graphics Tray Information button (choose "Save to File" and the raw EDID will pop up). Use the instructions from the DTD Wiki I referenced above to find the proper DTDs, paste one into the DTD field of the Reverse Calculation screen and hit the button there.

b) Another option is to find a Linux Modeline out there which someone has used for your monitor, and to input the parameters into the left panel, thus autogenerating the proper DTD for use with Intel graphics.

c) Another is to use a standard (provided), Consumer Electronics Association resolution by selecting one of the choices under "Standard Timings" in the Calculations tab.

In each case, the DTD Calculator tool will show the DTD across the bottom of the window, and will show the exact timing parameters in the left panel. Once you've inserted or selected a basic DTD, proceed to the Registry Hack section. You may or may not have DTDs on this screen (depending on if you've hacked them before or not), but if you want more resolutions than are listed shown there, click the More button. A blank DTD will be generated, ready to be stuffed into the registry. Since we've already got one selected, click "Get Calculated". This will take the current DTD and put it in memory as something you want to send to the registry as a selectable resolution. Repeat for as many as you'd like (up to five). When done, click "Write DTDs to Registry". Reboot, and the new resolutions you inserted should be selectable using the normal methods (Intel Graphics Tray or Windows Display Properties Settings).

Just as a note: if you write to the registry a resolution which matches, in description, one which the Intel graphics drivers are already providing ("1920x1080 interlaced @ 60Hz"), when the reboot occurs only one of the two will be selectable. Which is it? Is it the one you're using to do your overscan correction, or is the driver default one? There's no way to tell! So before putting your DTD in the Registry Hack screen, "tag" it by giving it a very obviously non-standard resolution. Changing the Horizontal Active pixels by 1 or 2 in the left panel is probably your best bet. That way you'll be able to distinguish between "1920x1080i @ 60Hz" and your custom "1922x1080i @ 60Hz". Don't be too worried about the exact resolution you select being "right"; this is just temporary, anyway. Your final overscan-free DTD will be something drastically different from the original and it's unlikely you will ever confuse 1920x1080 with 1898x1070. This method has the added bonus of fooling the drivers into being able to display resolutions your vendor (typically laptop) has (for whatever reason) specifically disabled in their BIOS.

4) Overscan Correction

At this point, especially if you've chosen 1080i or 720p, your TV probably has some level of overscan, meaning that the edges of your desktop or other content is beyond the edges of your screen, and you can't access taskbars or the minimize or close buttons. Highly annoying! Fortunately, that's the primary function of DTD Calculator: eliminating this pesky overscan. Open DTD Calculator, go to Registry Hack again, find the DTD which matches the resolution you are currently in and click Create Modeline to load the current DTD into memory.

Proceed to the Tuning tab, and click Ruler. Superimposed translucently on your desktop is a window you can use to find the right dimensions for your screen. Stretch it to fit to the edges of your screen (use the up/down left/right buttons to do fine tuning if your mouse hand is as jittery as mine) and when you're done click the Apply button. The new, non-overscanned screen size will be computed as a new DTD (you may notice the parameters have now changed.... or you may not, if you don't ordinarily memorize resolution timing parameters).

5) Fine tuning

You've sized the desktop appropriately, now, to fit your screen, but is the image where you'd expect it to be? Or is it shifted left, right... in some way askew? You can use the buttons on the tuning screen to ensure the image moves to the right spot on screen, and you can watch the little image move around the big black box.

6) Finalize
When you're done, and the resolution is as you like it, go back to the Registry Hack tab, choose one of the five available DTD "slots" in the registry, and click "Get Calculated" to change it to what you currently have developed. Click "Write DTDs to Registry" again to rewrite the new resolution to the registry, and then reboot. The new DTD will show up now under the regular resolutions. It's likely something really weird like 1820x996 or 1198x712, but it will be there and it should provide you with an overscanless screen to the limits that your monitor can provide. Voila!

7) There are other ways you can use the DTD Calculator-- a pure way of calculating a Modeline from the EDID (or vice versa). It's an excellent tool and I urge anyone who comes up with a useful application for it aside from what I've outlined here to post your experiences.

Afterword

Again, I ask you to be fairly kind in any suggestions or requests for new features. It's not my software (though it makes my life easier) and it is in fact provided by some folks who just thought it would be a nice favor to do for the community. They didn't write the Intel drivers, and while I and they will probably try to help with any weirdnesses as much as can be done, the bottom line is: if there is a driver problem, go to Intel.

This software is provided with no guarantees, express or otherwise. (At least, I think I saw lawyerspeak like that on some software once. Maybe it will do the trick.)

I reiterate my special thanks to AVS's very own Wo0zy and to his cadre of folks. Without them this software would have been solely in my head, and my Brain-to-IA32 compiler SUCKS. They went above and beyond on this, adding functionalities I hadn't thought of. I cannot say enough good things about them.

Need a bit more information mate. 25i & 30i and interlaced so not 1080p. 50and 60Hz could be. What does you screen support? Without your EDID information even archibael won't be able to help .

Try posting the report from the Intel Graphics tray and I'm sure someone will be able to help.

What happens when you try and write to the registry? Do you get an error or does it seem to work but after a reboot no new resolutions appear in the Graphics Tray? What OS are you running?

Cheers,

Hi again,

I finally found the settings I used for Powerstrip on my previous ATI X1600 PRO on XP Pro.
The thing that happend on the screen was that I could tune up Powerstrip to for example 1080P60Hz but the LCD only showed 1080P45Hz with this setting.
So my feeling is that the LCD HDMI HW speed limits at this refresh rate.
If I also tuned backporch to 0 the LCD could still follow a few Hz more.

The setting you see attached was functioning as above. The only thing I changed was the "Vertical geometry refresh rate" to 45 Hz fr it to reflect the rate that the LCD was showing.

I dont know what this would give as DTD?

(archibael, please check and mark my homework ).

Don't know if it'll work but that's the DTD.

That information suggests that 1920x1080 is already selectable in the Intel Graphics Tray. If it is then adding another with DTD Calc won't help. What you need to do is select your chosen timing (I'm guessing 1080p60) from the Intel Graphics Tray then launch DTD Calc and enter the following DTD into the reverse calculator

02 3A 80 18 71 38 2D 40 58 2C 45 00 00 00 00 00 00 1E

If you want 50Hz instead then select that and enter

02 3A 80 D0 72 38 2D 40 10 2C 45 80 00 00 00 00 00 1E

After that, use the ruler tool to adjust as needed (avoiding odd numbered pixel counts and odd numbered "H start of sync pulse" values) then save the new DTD to the registry and see if the new resolution is selectable from the Tray.

If it isn't you could be one of the few with "different" registry keys in which case a driver reinstallation might help. Are you using an English Language version of windows? Also if Vista, ensure you "right-click" on the DTD Calc icon and "Run as Administrator" (although if this was the problem, I'd expect and error when attempting to write to the registry).

Hope this helps,

Although manually decoding the Data Block in V3 has become a bit of a hobby now. Thanks for that mate not sure what I used to do in my spare time before I met you

Hello,

I've been searching all over the internet trying to find a solution to my problem, and came across this forum/thread, and actually found someone with my same display, but am still having problems.

So, here is the problem. I have a Sony kde-42xs955 (ALiS 1024x1024 native, according to the manual) attached to my mobo (A Mini ITX Jetway J9F2) via HDMI. Initially, I tried to use powerstrip, which I believe, tried to rush into with out really researching anything just got confused. So, I did a fresh installation of Vista (ultimate 64bit) and going through the initial pages of this thread helped my understanding alot more, but am still having problems. From reading forrums (entech, here, a few other places), I have foudn that with an ALiS 1024x1024 display, many chose to use the following:

Something odd I noticed and I don't know if it makes a difference, is that in display properties, it shows that I have 2 monitors hooked up, and intel graphics panel seems to revert to clone mode selected (under display devices>multiple monitors) even though I only have the Sony hooked up, and never have had any other display hooked up this pc.

Anyways, trying to use DTDCalc was unsuccessful, as another member in this thread had similar problems, but was able to resolve them, I was not. I've searched the display properties, intel panel and registry for the addition of new resolutions (I mainly tried 1024x576 and 1920x540) but they do not show up after reboot.

First, Is the 1024x576 resolution and aforementioned modeline correct to use on this TV? If not, which should I use?

Second, What measures should I take to try and fix my problem? Directly writing to the registry (risky), use powerstrip, etc?

All in All, I'm just looking for some help - if anyone could get me going in the right direction, it would be greatly appreciated. Thanks.

ps - this thread has already helped me alot! Thanks again!

Custom Resolution Tool for Intel Graphics Easier Overscan Correction

Hi cheeseman,

I can try and help with some of this but Archibael's wisdom will most likely be needed for the rest.

Regarding the DTDCalc issue. Firstly, have you searched the registry for "TotalDTDCount" and "DTD_1" yet?

Do the search from HKLM\System\CurrentControlSet\Control\Class and see what keys are found. Post #145 (kind of) explains what痴 going on with regard to the registry writing.

In a number of cases completely removing and then reinstalling the drivers can regenerate the keys needed for DTDCalc to work again although I have no idea why the keys don't exist in the first place Anyway, do the search and report your findings. There may well be a few keys with these values but a complete list would be helpful.

I assume DTDCalc "thinks" that it's written a DTD and it shows up on the "Registry Hack" tab?

Have you tried using the "Interpret EDID" tool yet with the EDID returned from the Intel report? (Ignore Moninfo as it doesn't report anything from the second data block). I've just done it and the EDID claims that 1080i60 (01 1D 80 18 71 1C 16 20 58 2C 25 00 10 09 00 00 00 9E) is considered the native resolution for your display (although if it's a 1024x1024 panel then it must be scaling).

Anyway, first things first, I assume you're getting some sort of image on the display in order to be able to try the things you have so far. What resolution is it and what's wrong with it?

Archibael may be able to comment on whether you're likely to get 1024x576 working (I don't know) but the Modeline you gave generates an error in the DTD (byte12=0X where "X" indicates an error) so without further adjustment that particular modeline isn't going to work.

I also don't know why you're seeing two displays in the report. Maybe something to do with the mobile origins of the 945GM chipset?? Again, Archibael will probably have a better understanding of this.

Lastly, don't use Powerstrip. It won't work in the way you want with Intel Graphics.

Sorry for the rather random comments but hopefully they'll give you something to think about and maybe try.

Yeah, the Vsync offset exceeds the VESA spec on that Modeline by a lot. Powerstrip can do nearly anything, but the Intel graphics are limited to "legal" resolutions.

I'd go with the "native" rez... it won't be perfect, but then again if you're trying to drive 576 lines on a 1024 screen, perfection is not attainable.

Quick replies...nice! I just got home from work, but will try doing all these things that you and W0ozy mentioned sometime today, thanks for all the help!

A few questions, when you say native res., do you mean 1024x1024? From other forums, I've also heard that some people try 1024x512 or something close to that, I dunno if that helps the situation any being that I'm not very educated on this subject. Second, reading this thread, I heard about the interpret EDID tool, but didn't really know where it was located (doh!), how do I get to that, and what are there any special instructions for using it?

Lastly, I know the instructions for using DTDCalc are on the first page, but could someone give me a quick run through of the process (related to my situation/EDID/DTD)? It's repetitious to have someone do it, but I was having difficulties rereading how to use DTDCalc...My brain fails me sometimes

Thanks again for all the help!

Hi Dan,

An EDID contains 1 (or more) DTD's (in most cases). These can be flagged as native (the resolution the screen is happiest running at) and non-native (supported resolutions that won't necessarily produce the best results). The EDID for your screen claim's that 1080i should be considered "native". Obviously, as your panel is 1024x1024, the native supported resolution doesn't mean 1-1 pixel mapping .

1024x512 could be 1024x1024 interlaced perhaps? But again, this isn't what your display is "expecting" to receive.

Regarding the use of DTDCalc, Archibael's instructions are about as easy to follow as it's possible to get with this topic (sorry). I'd suggest re-reading these first then asking any questions once you've tried it.

The "Interpret EDID" feature is new though. To use it, simply copy the 16x16"block" of Hex values from your Intel report to the clipboard then select the "Interpret EDID" tab and click "Paste EDID". The EDID will now appear in the top window. Then, click the "Interpret EDID" button and all (well nearly all) the information from your EDID will be displayed in the bottom left box with DTD's extracted to the bottom right box. Double-clicking on a DTD will fill in all the settings for that DTD ready for manipulation with the rest of the DTDCalc app (it effectively pastes the DTD into the "Reverse Calculation" tab and clicks "Reverse Calculate" ). If you check out the information in the bottom-left box you will also see a number of "Resolution Supported" entries that are calculated from the DTD's. The last comment on the end of each of these lines tells you whether the resolution is "Native" or "Non-native". In your case the resolution (and DTD) I gave you in the previous post is considered native.

From here, follow Archibael's instructions to add the timing to the registry using the "Regaistry Hack" tab. Once you've got the resolution available in the Intel Graphics Tray, select it and use DTDCalc to "fine tune" as needed i.e. correct position, overscan, etc. In order to try a new setting you must write the new DTD to the registry and reboot. You can either add it as a second DTD (which I'd recommend while experimenting) or over-write the first DTD.

One final note, if you already have 1920x1080 or 1920x540 selectable from the Graphics Tray then adjust the DTD slightly so you can "see" the new resolution. Make it 1918x1080 or something similar.

Good Luck

Custom Resolution Tool for Intel Graphics Easier Overscan Correction

Hello folks,

I just today discovered this forum and the DTD Calculator being discussed. I must say I've learned a lot in the past few hours, if only at a surface level. However, I have not yet solved my problem, which is as follows. I would appreciate any advice.

I have a new Samsung 42" LCD TV (LN-4061F), and I would very much like to use the PC VGA input with my Dell Latitude D510, running the Intel 915MGL video chipset. I cannot get a good widescreen video mode going, and this DTD Calculator seems to be a good solution. I can get a signal through on some modes that do not look very good because they are all stretched out, but what I am really hoping for is support for the native 1920x1080 resolution as it is the only truly good widescreen mode it supports.

Here is what the TV manual says it supports for that resolution:
Resolution: 1920 x 1080
Horizontal Frequency (kHz): 66.500
Vertical Frequency (Hz): 60.000
Pixel Clock Frequency (MHz): 138.500
Sync Polarity (H/V): -/+


** My question: I tried putting in most of these settings, but how do the Horizontal/Vertical Frequency numbers relate to the settings in DTD Calc? I don't see direct settings for those, and I don't know enough about offsets and whatnots to get it going. I've been 'tinkering' quite a bit, and I can get the new modelines that I write through registry hack to show up in the Intel software (after waiting forever for so many restarts), but the TV keeps giving me a "Mode Not Supported" error when I try them out. I got close once, where the TV went to aquire new signal and then thought about it for a really long time with no error, but never resolved the signal. Perhaps I am in the ballpark?

Here are some of the specs on my laptop (I tried outputing the report from the Intel software, but it did not include the raw EDID even in the text file.):
Dell Latitude D510
Intel Chipset 915GML
Driver Version: 6.14.10.4609
Operating System: Windows XP* Professional, Service Pack 2 (5.1.2600)
Default Language: English
DirectX* Version: 9.0
Physical Memory: 2039 MB
Minimum Graphics Memory: 8 MB
Maximum Graphics Memory: 96 MB
Graphics Memory in Use: 5 MB
Processor: x86 family 6 Model 13 Stepping 8
Processor Speed: 1862 MHZ
Vendor ID: 8086
Device ID: 2592
Device Revision: 03

P.S. This driver is the most current I can get for my Dell. For some reason the Intel release of 14.25.50 won't run on my machine, and it says I must use the manufacturer-supplied version. Doesn't seem to be a problem, as the modelines generated from DTD calc do seem to be showing up in the registry.

*** In a nutshell: Any suggestions for getting a DTD to run the TV specs above?

Thanks a million!

Custom Resolution Tool for Intel Graphics Easier Overscan Correction

Hello!

I'd just like to know if anyone got a custom DTD entry to work with the G35 conntected over HDMI to an LCD-TV.

I have an ASUS P5E-VM HDMI with onboard HDMI-connector and Intel G35 chipset. The Intel driver seems to make a difference between digital monitors and digital televisions, as my TV is listed as the latter.

What I really want to do is, force the Intel graphics to support some custom modes. Nothing fancy, let's start with 1920x1080@24Hz, as suggested by the EIA/CEA standard and listed in the DTDTool itself. I'd be happy already, if that single mode would work.

By the way I am running Vista (which I don't like, but is the only option for Bluray support) and the EDID of my LCD-TV doesn't list the 24 Hz modes, so no luck there.

@archibael: I think DTDTool is a very useful piece of software. I myself used to develop a little tool that allowed users to set custom refresh rates for Direct3D/OpenGL under Windows NT/2000/XP back when the nVidia Detonator drivers didn't support that (mostly only 60 Hz were possible). Now nVidia finally have their selection tool for custom modes. It was a similar problem that involed hacking cryptic resolution tables into the Windows Registry.

However, what I noticed about DTDTool is that (at least on my PC) it does create the DTD_1 entry and modify the TotalDTDCount value, there are only zeros in the DTD entries. So I get something like "00 00 00 ... 37 01". The reverse computation features seem to work fine, but I can't get the tool to write valid values.

Of course, I then tried to enter the DTD_1 myself with exact the same value your tool suggests for 1920x1080@24 Hz, but the refresh rate wouldn't appear under Monitor settings. What can be wrong with my entry. It's exactly 01 1d 80 40 73 38 2d 40 80 30 45 80 00 00 00 00 00 1e 37 01.

I also tested the other 24p mode, someone else suggested in this forum, which he got from Powerstrip listed as an electronics standard I believe. It begins with "01 1d 80 3e..." and the rest is the same. No luck, though.

Can you tell my what's wrong with my settings and why the mode doesn't show up?

I'd also like to have a look at the 816b standard myself and see if there are any other usable modes, but I didn't seem to find a table in the internet. Can anyone help me out?

Regards,

Yes. No problem at all and using the same Mobo as you.

Check out post #145. It explains which registry keys DTDCalc uses for reading and writing the new DTDs. Please compare your registry keys with those and if you find differences please post them.

There are some people that find this but nobody has yet come back with a complete list for us to look through.

As I mentioned further up on this page, sometimes uninstalling and then reinstalling the drivers creates the correct keys for DTDCalc to work with.

Also, does DTDCalc report the new DTD on the "Registry Hack" tab or is that all zero's as well? Again, post 145 will explain what DTDCalc is looking for when reporting the DTD's.

One final thing. If you're running the 15.8 drivers then it is very unlikely that you'll get 1080p24 regardless of whether DTDCalc is working or not. For some reason support for 24Hz seems to have been removed from the driver. You will need to revert to either 15.7.3 or (better still) 15.6.1 to get it. But be warned, most people claim that there is an annoying stutter at 24Hz on G35 and report smoother playback at 60Hz (go figure??).

That sounds promissing. But somewhere I read, that it might not be possible with TVs, but only with monitors connected over DVI, because the driver seems to somehow handle them differently.

The following registry keys are existent on my system:

* HKLM\System\CurrentControlSet\Control\Class\{4D36E968-E325-11CE-BFC1-08002BE10318}\nnnn

* HKLM\System\CurrentControlSet\Control\Class\{4D36E968-E325-11CE-BFC1-08002BE10318}\nnnn\Settings

* HKLM\System\CurrentControlSet\Control\Video\ANYSUBKEY\nnnn

* HKLM\System\CurrentControlSet\Services\ialm\Device

The key under "services" (ialm) exists, but does not contain any values whatsoever. The second key "\Settings" also exists, but only contains a value called "Device Description" containing a string like "Intel G35 chipset".

I already tried to reinstall the drivers when I added my 24p-line to the Intel INF file. After installing the modified INF file, the DTD entry showed up in the registry, however the 24 Hz mode didn't show up in the monitor settings.

The tool of course reports the correct DTD setting, but only because I entered it manually with regedit. If I choose the 24 Hz mode in the Calculation tab, click on "Get calculated" under "Registry hack" followed by a "write to registry", DTDCalc asks me wether I want to restart the system. Just for testing purposes this time, I choose "No" and click on "Read from registry" right away and what I see is "No Of DTDs" = 1 and DTD_1 = all zeros.

Thanks for the warning. I have come across these threads, but I want to see myself out of curiousity. Also, maybe ReClock can do something about it. I will also try a previous driver version and let you know if it works.

Custom Resolution Tool for Intel Graphics Easier Overscan Correction

Hi drickels01,

So many potential pitfalls

This may take Archibael to resolve but I'll take a stab and see where we go from there.

Firstly though, to answer your question, there are no direct entries for H & V frequencies in DTDCalc. However they are there hidden behind the numbers

The Refresh Rate is the Vertical Frequency.

The calculation for this is

Pixel Clock(Hz) \ (Total H pixels x Total V Pixels) = Refresh(Hz)

So, if you load up the standard EIA/CEA timing for 1080p60 you will see that the calculation will be as follows

148500000Hz \ (2200x1125) = 60Hz

or

148500000Hz \ 2475000 = 60Hz

You'll notice that we're using the total number of horizontal and vertical pixels not just the Active Pixels for both H and V (the values indicated in "H End of Blanking Interval" and "V End of Blanking Interval"

The Horizontal Frequency can be calculated by using the formula

(Refresh Rate(Hz) \ 0.95) x Active Vertical Pixels = H. Frequency(Hz) \ 1000 = H. Frequency(KHz)

Using our 1080p60 EIA/CEA example this would be

(60 \ 0.95) x 1080 = 68210Hz (rounded) or 68.21KHz (rounded to 68Khz)

As you can see, all of the values for the EIA/CEA 1080p60 timing are fairly close to the timings given in the Samsung manual (within 5% for the H. Frequency and within 10% for the Pixel Clock) so you may find that the standard timing will work for your TV.

Maths isn稚 my strongest subject so Archibael may wish to comment on this and may well know of an easier way of calculating this stuff.

Anyway, we could now start experimenting with the values to get closer to the timings in your manual but this would be a rather long and random process so, forgetting the maths for a second, I did a quick Google and found the following modeline for what I think is your TV

"1920x1080" 138.500 1920 1960 1995 2083 1080 1082 1087 1109 +hsync ?vsync

Note that the H and V sync are the other way round to the information you gave which is odd and not only that but DTDCalc thinks it痴 H+ & V+.

Anyway, try putting the following DTD into the reverse calculator

1A 36 80 A3 70 38 1D 40 28 23 25 00 00 00 00 00 00 1E (this is the DTD calculated from the above modeline)

Then add it to the registry, reboot and see if it痴 selectable from the Intel Graphics Tray.

If it is but it doesn稚 work, try changing the sync profile to ?h +v as per your manual, save to the registry and try again.

If either new timing isn稚 selectable, try changing it slightly (to say 1918x1080) just in case your Video BIOS is preventing it from showing up.

Finally (and sorry for asking such a basic question), are you sure the manual says that 1920x1080 is supported via VGA and not just via HDMI? I致e come across Samsung痴 in the past that are quite restrictive when it comes to VGA.

Man, that痴 got to be my most rambling post to date.

That sounds promissing. But somewhere I read, that it might not be possible with TVs, but only with monitors connected over DVI, because the driver seems to somehow handle them differently.
Works fine with TV's but obviously only timings supported by the TV will actually work

The key under "services" (ialm) exists, but does not contain any values whatsoever. The second key "\Settings" also exists, but only contains a value called "Device Description" containing a string like "Intel G35 chipset".
How any "nnnn" keys do you have? Does the new DTD exist in the highest value "nnnn" key? Perhaps you could export the entire key and post it here for us to have a look at?

This is what I would expect if you're running the 15.8 drivers. 24Hz doesn't show up. It will with the previous drivers.

Just for testing purposes this time, I choose "No" and click on "Read from registry" right away and what I see is "No Of DTDs" = 1 and DTD_1 = all zeros.
There's definatley something that happens differently in the registry for some people only. If you can post the exported keys we might be able to get to the bottom of it.

Like I said, if you are running 15.8 I don't think you'll be able to. You will if you use the previous drivers. Also, I thought there were issues with ReClock and Vista?

Hello Wo0zy!

You were right, reverting back to the previous release made the 24 Hz resolution available for me. With only one DTD entry I now have two more refresh rate options (23 Hz and 24 Hz). Thanks for the helpful hint.

Together with ReClock I think I have achieved a fairly smooth playback, but that remains to be investigated a bit more this evening by watching a good movie. :-)

On a sidenote: Unfortunately PowerDVD doesn't seem to make use of ReClock. Furthermore, the playback under 24 Hz is completely jerky and full of judder, however only in fullscreen. I don't believe the performance load is too high as other H264 Full HD movies (from disk) play fine.

As for the registry problem with all these zeroes: I can still reproduce that with the older drivers. For further testing, I can always change the reg values myself, but for your convenience I have attached the exported registry keys. Good luck in finding the bug.

I tried running the tool as administrator by the way, but the problem remains the same. I don't believe it's a rights issue, because the DTD entries exist, they just aren't correct. It is more likely that the method the tool uses to write to the registry is errorneous or incompatible to Vista.

I still would like to have a look at the standard timings suggested by the consumer electronics association, but can't seem to dig up the specs on the internet. Can anyone provide an excerpt?

Thanks for your support so far, I will keep you updated on my progress.

What build of PowerDVD are you using? The latest (3730) has problems with G35 which are still being investigated. Revert to a previous version of that as well and things should improve.

Having said that, I don't fully understand the post. Do you mean playing H.264movies through PowerDVD at 50 or 60Hz is fine or playback through another application is fine? Could you clarify? Thanks.

You're correct regarding ReClock. I knew I'd read it somewhere.

Thanks for the keys. I'll be taking a look later. You do have to run as administrator for the Reg Hack to work but it you weren't you'd have got an error message (assuming you have UAC enabled).

It's not as simple as just being a Vista issue. It works fine for me and many others under Vista. Like I said before, there do seem to be some people that have this issue but not many. Hopefully your keys will provide a clue.

Even if you can't use DTDCalc to write the EIA/CEA timings to the registry you can still get the information you need from it. Just select one from the "Standard Timings" drop-down and "cut & paste" the DTD. All you need to do is add "37 01" to the end and manually add it to the registry.

Hi locutus266,

Where does the manual DTD entry get added in your registry?

So far the first thing I've noticed about your keys is that there is no DTD_2,3,4 or 5.

Normally, during the driver installation these should be written as

HKR,, DTD_1,%REG_BINARY%, 01,1D,80,18,71,1C,16,20,58,2C,1A,00,00,00,00,00,00,86,37,01 ;1920x1080@60...Interlaced
HKR,, DTD_2, %REG_BINARY%, 01,1D,80,D0,72,1C,16,20,10,2C,1A,80,00,00,00,00,00,86,37, 01 ;1920x1080@50...Interlaced
HKR,, DTD_3,%REG_BINARY%, 01,1D,00,BC,52,D0,1E,20,B8,28,25,40,00,00,00,00,00,04,37, 01 ;1280x720@50....Non-interlaced
HKR,, DTD_4, %REG_BINARY%, 01,1D,00,72,51,D0,1E,20,6E,28,25,00,00,00,00,00,00,06,37,01 ;1280x720@60....Non-interlaced
HKR,, DTD_5,%REG_BINARY%, 00, 00, 00 ,00, 00, 00,00, 00, 00,00, 00, 00,00, 00, 00,00, 00, 00,00, 00 ;Fifth DTD

with "TotalDTDCount" set to "0", but they don't appear on your system?

If you can confirm the location of your working manually added DTD then we may be able to come up with a workaround. Having said that, it would also be nice to find out why your (and some others) driver installation is different to most peoples? Very odd

Perhaps Archibael can hazard a guess?

Thanks for the information,

Perhaps he manually generated the DTD_1 value in a driver which didn't have it, then when he eventually installed one which did it didn't get deleted? I'm stumped.

That's just because I have deleted all those bogus entries from the INF file before installation. Nevertheless, I reinstalled the drivers numerous times and the tool never worked as expected.

When I do enter stuff manually, I do so in the key

HKLM\System\CurrentControlSet\Control\Class\{4D36E968-E325-11CE-BFC1-08002BE10318}\[0000 and 0001]

When I browse to the video keys after (!) that

(HKLM\System\CurrentControlSet\Control\Video\ANYSUBKEY\[0000 and 0001])

the values normally are already in place. My guess would be that (at least on my Vista system) the keys under CurrentControlSet are mirroring the keys under video, so when I change something there, it automatically gets changed in video. I don't think it's the other way around though.

Under the ialm key there's nothing to change really, because it's almost empty. When I was coding that nVidia refresh fixer I mentioned earlier, I was doing changes in exactly the same places by the way, except the stuff under CurrentControlSet.

My observation was, that under Windows 2000, the nVidia registry settings would be kept under the key HKLM\System\CurrentControlSet\Services\[nvidia service name] whilst under XP they would be kept under the video key redundantly. Win2000 didn't have a video key, by the way. So it's entirely possible that under Vista things are a little bit different, once again. I had to implement different approaches in my tool to accommodate for these differences and do a check what OS is running prior to that.

Hope that helps.

Regards,
locutus

Hi locutus266,

I知 now even more confused.

This is exactly where DTDCalc should be writing the values and does in most cases.

I値l ask Paul (the guy who wrote the software) to take a look and see if he can spot anything but I hate going back to him with an intermittent issue that I can稚 reproduce (he just looks at me funny ).

Anyway, the information is very much appreciated and I知 sorry it doesn稚 work for you.

Cheers,

Hello Wo0zy,

the software has been quite useful for me even without being able to write to the registry.

Together with the EIA/CEA Full HD standard for 24 Hz, ReClock, Media Player Classic (set to VMR7 windowed), and the Intel drivers prior to to 158, I have been able to achieve smooth and judder-free playback for any kind of movies MPC is able to play, even under crappy Vista. With ReClock I can also render 25 fps PAL videos at their original rate of 24 fps, so I got something similar to WinDVDs "PAL TruSpeed" feature.

I haven't been able to make PowerDVD work with ReClock, but I am sure, future versions of PowerDVD might improve playback quality. After all Blu-ray playback is a fairly new feature and we all know that commercial software mostly is not the solution you really need/want/can make use of.

Actually, the average user would look at the beautiful colours and be happy, but for people like us, it always has to be perfection :-)

Hello all,

Just a fast question for archibael or Wo0zy Sorry if this has already been asked

I'm a G90 CRT projector owner and I've been always watching HD-DVD and BRD softwares on my HTPC using specials 1080p48/p50 modes (with Powerstrip ->Nvidia GC).

I just upgraded my HTPC with the Asus P5E-VM HDMI M/B and wonder if I can still create the following "custom resolution" (DTDCalc) for my projector with the embedded Intel graphic card ?

1080p48:
Mode = 1080p47.952
Freq.H = 53.946KHz
Sync.V = 47.952Hz
Pixel rate = 118.681MHz
Syncs = H+/V+

Advanced Parameters :
Hshift=148
Hsize=1920
H_Front=88
H_sync=44
H_Back=148
-----------
Vshift=36
Vsize=1080
V_Front=4
V_sync=5
V_back=36

1080p50:
Freq.H = 56.25KHz
Sync.V = 50.00Hz
Pixel rate = 123.75MHz
Syncs = H+/V+

Advanced Parameters :
Hshift=148
Hsize=1920
H_Front=88 (Instead of initial 528 european standard value not suitable for CRT projectors)
H_sync=44
H_Back=148
-----------
Vshift=36
Vsize=1080
V_Front=4
V_sync=5
V_back=36


Thanks in advance !

Glad you found a copy of the spec.

Well what are ye waitin' fer, man! Post yer settings!!!!

How do they differ from the "generic" ones I calculated for DTDCalc?

Nvidia and ATI drivers support sub-pixel resolutions and Intel's don't, so you won't be able to get those exactly, but you can get as close to those as VESAly possible using DTDCalc. You can translate those into the parameters accepted by DTDCalc (which essentially uses Linux Modeline coding) by the following transforms:

Pixel Clock = Pixel Rate
H Active Pixels = Hsize
H Start of Sync Pulse = Hsize + H_Front
H End of Sync Pulse = Hsize + H_Front + H_sync
H End of Blanking Interval = Hsize + H_Front + H_sync + H_back

V Active Lines = Vsize
V Start of Sync Pulse = Vsize + V_Front
V End of Sync Pulse = Vsize + V_Front + V_sync
V End of Blanking Interval = Vsize + V_Front + V_sync + V_back

If I'm reading the specs correctly (and I admit I may not be). You were SPOT ON!

(At least for 1080p24. I haven't gone through the rest yet ).

Obviously the pixel clock is questionable but I guess 24 dead was considered the best bet (you know what they say about a little knowledge. Goes double for me ).

Cheers mate.

I have a shuttle SG33G5M.
I want to watch x264 movies on a 42pfl9632 on 1080p/24hz.
When i use dtdcalc. and i set 1080p on 24hz, and change the pixellines to 1081, after reboot I can choose this res. but my tv does not exepts it.(black screen)

I've tried the same resolution 1081 on 50hz and the tv does not exepts it either.

So my question is if it is possible to delete the resolution 1080p/50hz that intel provides and then put my own resolution 1080p on 24hz without having to change to 1081 lines.

btw: my tv supports 1080p 24hz.

Thanks...

Hi depp,

I have to ask . Why are you wanting to change to 1920x1081?

Does the standard 1080p24 timing work?

If you're just creating 1081 to get it to be visible/differentiated from the standard 1080s, I'd muck about with the horiz rez instead (1918 is a favorite of mine). TVs are a little forgiving about a couple of pixels horizontally, but when it comes to entire vertical lines they can be mean and rotten and evil.

I know it shouldn't matter in modern times when displays are digital grids, but for simplicity and interoperability, video data is still sent in essentially the same way as it was on CRTs.

I can't choose the 1080p24 by default. only 25p 30p 50p and 60p 1080.
But the intel program shows me on the infotab my screen accepts 1080p24.
Philips also says the tv accepts 1080p24.

I've tried 1080p30 and even that doesn't work with 15.8 so it's not only 108024p. 1080p50 works fine.

Are you sure it's 1080p no 1080i? If it's directly selectable from the Graphics Tray then it's probably 1080i.

Still, not great news

I'm wondering whether it might be best to recommend returning to either 15.6.1. or 15.7.1 ATM. AFAIK the HDMI situation hasn't changed since then and for HTPC use I can't point to any serious fixes in the last two updates that count for much.

Hopefully we'll hear from Archibael soon. Fingers crossed for his attempts to get greater visibility within the Intel support structure.

Archi, Level 0 is a great idea. I for one would do anything I can to help.

Hi ptr727,

While I'm sure no one will mind you posting the information here, you might get greater exposure posting in the G35 thread (http://www.avsforum.com/avs-vb/showt...938473&page=32) or maybe even starting a new thread.

Personally I can't offer much help regarding SP1 ATM (still a lot of testing to do).

So far I'm not seeing a benefit to 15.8, and I don't have any visibility to it beyond that. I'd go 15.6.1 if possible, as it was 15.7 which started the "default to 800x600" trend.

Wo0zy 1080p30 was selected from the new DTD Calculator, I just assumed it was progressive not interlaced. I get interlaced "for free" in the display settings.

Okey, an update to my situation

I downloaded the newest driver from Intel, manually altered the .inf file (can't get the EDID data from my LCD) by adding standard timing of 1280*720@60Hz which I got from DTD Calculator. Didn't work, so I downloaded the driver from HP (it was a bit older version) and did the same thing and voil?! Now I can select (mystically) both 1280*768 and 1280*720, which weren't availlable before. But.. as I was afraid my LCD is not supportig either one of those. Though, I'm quite sure that using my old laptop (which has some other graphics driver, can't remember..) I used 1280*720 quite alright.

But anyway I'm (for the first time in few days) having hope with this issue, cause now I know I can manually hack the .inf file and it works! Now I just need the correct DTD for 1360*768@60Hz.

Cheers for all the help guys!

Still no success.. Now I tried adding what archibael suggested to Oddish on page 12:

Oddish,

Never was able to find an EDID for your monitor, however the -40V2000 gives

to the .inf file, which now looks like this:

Installed the driver with this, it gave some notice about the validation of the driver on the way which it didn't do on last installation. Anyhow I could click "install anyway" and it did. Still, 1360*768 isn't availlable. Any ideas? Could it be restricted in the BIOS? Anyway now I have a much wider selection of resolutions in both control panel and graphics tray, problem is my LCD seems to be quite picky, so only 1360*768 would be acceptable..

You're probably right if you added it with DTDCalc and the interlaced check-box wasn't selected.

It is interesting that 15.6.1 is the driver still be offered on the Asus website (assuming I'm correct that build 1329 is 15.6.1)

http://www.intel.com/support/graphics/sb/cs-009479.htm seems to suggest it is.

Hi archibael, Wo0zy, and everybody else. Thanks to this thread and the utilities linked from it, I was able to add a custom 1920x1080x24fps resolution on my Q35 chipset integrated graphics (Intel DQ35JO motherboard with latest BIOS that just came out 2 days ago). I'm using Vista 64 with 15.7.3.64.1409 graphics drivers. I thought that things were working fine...

The integrated DVI is connected with a DVI-to-HDMI cable to my Sony XBR4 LCD. When I leave the computer on, and turn off the TV, and later turn the TV back on, that's when I have a problem. When I turn the tv back on, I hear three or four windows sounds similar to when you plug in or remove a usb flash thumb drive. A couple of times I've seen it come back in 800x600 mode. One time I saw it come back in 1920x1080x24 mode, and the graphics options didn't list any other modes available other than 1920x1080x24 and 1920x1080x23. It is definitely annoying.

Blu-ray and HD DVD playback is fairly good, but I do see a few dropped frames. I currently have an E6700 cpu, but will soon be getting a Q9550, so that should fix those few dropped frames.

Hi gorthocar,

Nice feedback
You're no doubt aware that the resolution reset issue is being reported by several people. Unfortunately it's proving difficult to pin down any sort of pattern .

May I ask if you've installed RTM SP1 yet?

ptr727 requested feedback on an issue returning from standby so I thought I'd install it last night in order to test and so far I haven't had a reoccurrence of the resolution/ black screen issue. Admittedly it's only been 24 hours (which means a maximum of 3 tests in my case) but still promising. Also, I'm still running 15.8 drivers as well and I wouldn't recommend you update to those yet until the mystery of the missing 1080p24 timing is resolved.

You could follow archibael's suggestion and revert to 15.6.1. AFAIK nobody had this problem back then.

ptr727, I'll get to the standby testing tomorrow mate.

Hi ptr727,

Couldn't wait 'til morning.

So far I can't reproduce your problem

In fact the Sp1 and 15.8 combo seems to be behaving very well so far (fingers crossed).

Obviously I'm running a different MoBo to you so perhaps there is a BIOS issue with the DG33TL (even though the report seems fairly conclusive). Also, what version of the INF's are you running? My test system is running INF_AllOS_8.4.0.1016_PV_Intel.

If you want me to check anything else please let me know. I'll keep testing and report any change in behaviour.

Custom Resolution Tool for Intel Graphics Easier Overscan Correction

Hey All,

I just recently built/configured an HTPC using the ASUS P5E-VM HDMI mobo (G35 Chipset).

I have the htpc connected via HDMI to my HD LCD TV (37", 1080i).

I'm currently having a problem with the display results. First, it was the overscan issue (at 1280x720, there were significant overscan issues, same with 1920x1080). I used DTD to have a look and tinker with the EDID values. According to DTD Calculator, my tv supported 1280x720 and 1920x1080 (which is what I figured it would).

I adjusted the overscan on the 1280x720 so that it would fit the screen. The problem now is that text looks... well. not good. Is this normal? Is there really much that can be done?

I then decided to try my luck with the 1920x1080. With this resolution, there is overscan, and there is alot of Jitteriness. It looks as though the refresh rate isn't good enough. Could his be related to the type of HDMI Cable you use? Again, I used DTD to tinker with 1920x1080 to fit it into the display. The resulting resolution was 1819x1012. However, when I apply this "new" resolution, my screen goes black and nothing comes back. I changed the A/V input with the remote to switch from HDMI to AV1 then back to HDMI and the picture is there, but it's really distorted (the top half of the desktop is shown on the bottom half of the display, and the bottom half of the desktop is shown on the top half of the display!!).

This is really strange behaviour and I can't seem to find a way around it. Does anyone have any recommendations? My TV is Philips, 37PF9631D.

Regards,

Craig

Hi Craig,

According to the specs, the 37PF9631D has a native resolution of 1366x768 so any 1080 image will be scaled by the screen. Also, according to your manual the screen only supports scaled 1080i not 1080p signals. These two factors probably explain the jitter and other problems you're having with 1080 DTD's. Feel free to post your DTD and we can have a look.

Regardless, I think you need to aim for as close as possible to the native resolution. The manual for your TV doesn't mention support for 1366x768 over HDMI, only 1280x720 (720p) so this is what I'd suggest you go with.

When you adjusted the 720p overscan did you use DTDCalc or the sliders under the "Aspect Ratio" button in the Intel Graphics Tray? In my experience the sliders (if available to you) do a better job of scaling the desktop but a custom DTD does a better job with video content. If you used DTDCalc, make sure the resolution you ended up with is exactly 16:9 and that the vertical pixel count is an even number. Again, feel free to post your DTD (if you used DTDCalc) and we can check this for you.

One final thought. Make sure you haven't selected/enabled any zoom options on the TV.

I can't see anywhere in the manual to enable PC HDMI/Exact Scan/ Just Scan unfortunately and it appears that the VGA input only supports up to 1024x768 so the options outlined above are your only choices.

Hope this helps.

Hey Wo0zy,

Thanks for the informative and helpful response! I really appreciate it.

I am work right now but when I get home I'll post my DTD for all to see. Right now I am using a DTD Modified 1280x720 resolution (I believe I have it as 1216x7XX, I can't remember exactly what the resolution is). How do you ensure that your final resolution is 16:9?

For the TV, I have set it to Widescreen (no zoom)


Will definately post all DTD/EDID info when I get back home tonight.

Thanks again for all your help.

No problem

There's probably an easier way to do it but if you divide the number of horizontal pixels by 16 and then divide the number of vertical pixels by 9 you should get the same answer if the aspect ratio is exactly 16:9

For example

1920/16=120
1080/9=120

Wo0zy

Hey Wo0zy,

Thanks for the info. I should have realized this (doh!). Easiest way I can think of doing it is say, decide on the horizontal resolution (say 1920) and then find what vertical resolution will satisfy the 16:9 ratio. That is, form the following relationship:

eg. For Horizontal Resolution 1920, what vertical resolution satisifies the 16:9 ratio requirement

16/9 = 1920/x
Solve for x
16x = 9 * 1920
16x = 17280
x = 17280/16
x = 1080

Hi all,
I was wondering if anybody had tryed or got to work 720@24p/23.9p ....this would be really usefull to me if possible as I have re-encoded many of my HD movies to 720 to save space and my projector outputs at 720p (although it accepts 1080@24p and provides silky smooth playback). The idea really is to prevent as much scaling as possible really (and also let the HTPC do the scaling with 1080p material rather than the projector!!!). Any help or light you could shed on this would be greatly appreciated.
Cheers,

Custom Resolution Tool for Intel Graphics Easier Overscan Correction

Hi Jiff,

It's certainly possible to create a DTD for 720p24 using DTDCalc but I don't think your PJ will accept it. You might be able to get 48Hz working though

If you want to try it, import your EDID (which you should be able to get from the Intel Diagnostic Report) into DTDCalc (using the interpret EDID tool), find the closest 720p timing (assuming there is a DTD for 720p in your EDID ) and use that to adjust the settings. If you have a 720p50 timing then a small adjustment to the pixel clock should be enough to get you to 48Hz. If your EDID doesn't have 720p listed you could use the 720p50 "standard timing" from the "drop-down" list on the calculation Tab.

Custom Resolution Tool for Intel Graphics Easier Overscan Correction

I only get a black screen when connect my Toshiba 56H80 component 1080i input to G33/G31 IGP via Audio Authority 9A60 Component Transcoder. I VNC in to my computer and set the G33/G31 Screen Resolution to 1920 x 1080 and refresh rate to 30 Hertz, but nothing. Odd thing is that when I exit and restart the Intel Graphic Properties tool, the refresh rate is reading 60 Hertz, so I set it back to 30 Hertz and apply and OK. Go back, and it's reset to 60 again.

Whenever I connect an ATI card to this same setup, I just "Add 1080i30 in the Display Manager (NTSC)" and that setting gets me picture.

Is there any way to copy the working ATI settings into the DTD Calculator and thus into the registry for my G33/G31 to use?

ChuckKahn

Custom Resolution Tool for Intel Graphics Easier Overscan Correction

For 1080i, refresh should be 60Hz anyway. It's 30 full frames per second, but they're divided into 60 fields per second interlaced.

What driver are you using? Have you tried 15.6.1 from the Asus website?

It should be 60Hz, but 30Hz is the only setting that has ever worked on the three ATI models I've run with the 9A60+56H80 (not using PowerStrip). I'm using the 7.14.10.1409 driver. (Acer came preinstalled with 7.14.10.1283 which gave me choppy video playback, even with low CPU usage, so I used device manager to search the internet for updates.) The Intel site says version PV15.8 (7.14.10.1437) is the latest for Vista 32, is there something special about the Asus driver?

If you were to install Powerstrip on your ATi system and then find the reported information for the current config (front porch, back porch for H&V, pixel clock, etc,etc), this could be interpreted into a DTD for use within DTDCalc.

I haven't got Powerstrip installed ATM but I can do if you need help with this. If not Archibael can probably remember exactly where to look from memory.

The Asus driver is older (15.6.1) and doesn't have so many issues regarding resolutions. I know it sounds crazy but....

If you can't get an image using standard timings reported in the Intel Graphics Tray I'm not sure this it will necessarily help but you could give it a go.

Latest version of DTDCalc has the values for at-spec 1080i60.

I think you want 1080p30 if you believe the 30Hz value is the right onw. 1080i30 is half the pixel clock of spec 1080i and I don't believe your TV will actually accept it. If it did, regular component 1080i inputs from a DVD player or cable box wouldn't work.

We've found the only place in the registry that holds the EDID. In fact there are sub-keys for every monitor you have ever connected to the system (which on my demo unit is quite a few). Unfortunately we can't work out a simple way of using this information. Just deleting the key has no immediate impact on the system and as soon as you reboot the key is automatically recreated again. Replacing the EDID also has no impact and on reboot the original data is restored.

I guess this means that that the Intel drivers read the EDID from the display device on every boot (which you would expect) and then just write the reg key based on the results. Perhaps the information is used as a reference point for some other part of the driver although, as I say, deleting it doesn't seem to affect anything.

We'll keep looking but I'm not hopeful at this stage.

That would be heaven. As it sits right now I am regreting buying this MB. The analog out is buzzing through all my speakers for some reason even on a surge suppressor. I don't know what I can do to address that but until I can I can't get the full intended use out of my newly built system.

I was going to buy an LG BR/HD-DVD drive but maybe I will wait for now.

Actually, the BIOS differentiates between LFP, CRT, etc. So it still could be the case. That's why I've been specifying 1278x720 DTDs for you.

I'd try the 15.6.1 drivers.

For example: I watch on my HTPC via HDMI. Then I switch input on my TV to use another source. Then I go back to HDMI to use my HTPC again, the resolution has changed to 800x600 from earlier 1360x768. Is there a driver issue with G35 chipsets causing this?
I have the same problem, and I belive it has been discussed earlier in this thread. Anyone know of a solution to this problem?
There was a theory that this was introduced in the 15.7 version of the driver, but I haven't seen any confirmation of this.

This certainly didn't happen prior to 15.7. I'll be doing some more testing over the weekend with various versions and see if I can pin it down.

@Woozy and Archibael

I have a pc with ati radeo 9700pro connected to my projector (and 1280x720 ...)
I can't have EDID ; i use a script (visual basic) to have it but it don't work (it work with a crt) ;
Quote:
[ Monitor_1 ]

EDID_VESAManufacturerID : Bad EDID

???


I do not think the bios of my laptop prevents 1280x720 because it works with a CRT.

I noticed that when I use a modeline for 1280x720, often I can not choose 1024x768 (only 800x600): is it normal?

I,ve tried both XP and Vista but same problem occurrs.

Right now I run Vista 32 bit, and I can't find an older driver to try with.

They've been reported, and are not yet closed. Whether active work on them is being done I do not yet know. They just released the first 15.9 beta (previous was an alpha), not sure how that one's working out.

Right-click on the Desktop and select "Personalize" then "Display Settings". This will launch the main windows display configuration page.

Hi archibael - I'm still running the alpha drivers (all OK) but for some odd reason the driver no longer shows the 23 / 24hz options I had previously. I've used DTD Calculater to add back into the registry the standard listing for 1920x1080@24 and low and behold I've now got listed BOTH 23 & 24hz again...any idea what the 23hz is (if I select it I actually get 60hz)?
Thanks
Nathan

FYI - was just testing the alpha drivers to see if the 17sec stutter was still there on 1080p/24hz - unfortunatly it is...

Which keys? As Wo0zy indicated, some may be getting filled out which have no effect. Also, it should have "37 01" at the end, after "1E". Finally, please change it to

FA 1C FE 74 41 D0 1E 20 6E 28 55 00 00 00 00 00 00 1E

This is very important, as it's possible your BIOS is forbidding 1280x720, and since this is 1278x720 the restriction would go away.

Ensure that you're "extending" the monitor rather than cloning it from your laptop display. In XP, the checkbox for "Extending" is in the Display Properties. Not sure where it is in Vista, but it should be similar.

On XP it's under Advanced | Monitor. Anyone with Vista know where it is there?

Do you have Powerstrip installed? If so, uninstall that bad boy. It mucks with getting the registry working properly. Do you have a driver file like a monitor.inf installed for your monitor? De-install; generally speaking, those files only provide restrictions, not capabilities.

If all else fails, roll back to 15.6.x drivers and see if those work. 800x600 default resolution weirdness began on 15.7 and this may be a residual effect.

Taz,

Can I also ask you to add the new DTD using DTDCalc first then do the manual search as per Archibael's instructions. If you find any entries that haven't been changed by DTDCalc (mainly under any "currentVersion" keys as these should be the only ones that really matter) it would be really helpful if you could report them.

Thanks and good luck.

If there's no EDID detected on the ATI card, it has to be pushing generic 1280x720x59.94, which is

FA 1C 00 72 51 D0 1E 20 6E 28 55 00 00 00 00 00 00 1E

However, given that you have not been able to get any of these things to show up in your list of resolutions, I'm thinking that's not the problem.

You need to get one custom resolution of some sort to show up in your list or all the DTD calculations in the world will not help you.

I'd try it old school:

1) Type regedit at a command line
2) Do a search with F3 for TotalDTDCount. Change each occurrence (there may be twelve or so) of this to 1
3) Do a search with F3 for DTD_1. Change each occurrence (again, there are a lot) of this to

FA 1C FE 74 41 D0 1E 20 6E 28 55 00 00 00 00 00 00 1E 37 01

4) Reboot.

Make sure "Hide Modes that this monitor cannot display" is unchecked in Graphics Properties | Advanced.

If you're still not seeing it, something is seriously awry. I'd roll back to 15.6.x drivers and try again.

archibael

Custom Resolution Tool for Intel Graphics Easier Overscan Correction

Yeah. Lack of EDID shouldn't really be a problem; a DTD override should work either way. Heck much of the reason a DTD is necessary is that EDID is sporadic. If it's not the registry and it's not being limited by clone mode or something similar, I'm out of ideas.

archibael

Custom Resolution Tool for Intel Graphics Easier Overscan Correction

I have a good news !

I take another laptop (the laptop of my boss), Asus with Ati Radeon 1100 express.
I can use 1280x768 with my projector, and i can force 1280x720@59Mhz with the Ati Control Center (it doesn't work with 1280x720@50Mhz).
So I run Moninfo but i have no information about the projector : no modeline, no EDID.

How i can have THE information which can help you to help me ?

Tazdunord

Custom Resolution Tool for Intel Graphics Easier Overscan Correction

Looks like the Database rebuild lost the last page of posts

Archibael,

I got Taz to try generating an Intel report with only the PJ active and the resulting .txt doesn't include any EDID information and states the only supported timings are 800x600 16-bit colour?? Running in either dual display mode or with the internal display only, the report includes the EDID for the laptop display.

Taz,

I think the problem is going to come down to one of three things.

1. The projector is limiting the maximum resolution via VGA
2. The laptop's video BIOS
3. Drivers. The drivers can't read the EDID or there is no EDID.

The missing screenshots you originally posted seems to suggest that DTDCalc is working correctly and as you've also tried manually entering the DTD's into the registry as well, I think we can rule that one out for the time being.

It's going to be hard to prove one way or the other unless you can get another laptop/PC with a different Graphics solution to try with the projector. Guess we can try and eliminate "2" by trying Archibael's trick of using a slightly altered DTD which the video BIOS doesn't "block"

01 1D FE 72 41 CE 20 20 71 30 65 00 00 00 00 00 00 1E

might do it (what do you think Archi?).

Other than that, I'm not sure what else we can do

Wo0zy

Wo0zy

Custom Resolution Tool for Intel Graphics Easier Overscan Correction

I don't understand, either. I've never seen someone so limited in resolution. You should be able to get the standard 1280x720 (native resolution) without a problem over HDMI or VGA.

Are you trying to do "Clone" mode instead of an extended desktop or the projector alone? If your laptop screen resolution is 800x600, you won't be able to display any higher than that on the projector in Clone mode; you're limited to the lowest of the two.

I've come up against this with a few screens, the most recent being a Samsung Plasma. It had a native 720p resolution but for some reason this can only be achieved via HDMI.

Having said that is this the correct manual?

panasonic.co.jp/pavc/global/projector/manual/download/PT-AX200E_En.pdf
(I can't post image)


(sorry it's in English)

If so, have a look at page 45. It seems to suggest that 1280x720 and 1280x768 should be supported. Is this different to your manual?

You could try

E2 1D 00 70 51 D0 1E 20 70 30 55 00 00 00 00 00 00 1E
or
C4 1D 00 98 51 00 22 30 30 70 13 00 00 00 00 00 00 1E

Failing that

01 1D 00 70 51 D0 1E 20 70 30 55 00 00 00 00 00 00 1E


I also found this on another forum. I know it's not your exact model but it seems like many Panny users have issues with VGA

"I got the AX100 running off a HTPC. Orginally when it first came I played on it with a VGA cable since my DVI-HDMI cable hadn't arrived. The text didn't look like 1:1 mapping at all. But I found that was for two reasons, firstly I had keystone correction on and secondly I hadn't changed any of the settings (H&V). You can select auto and it works out."

This is refering to 1280x720@60

Let me know how you get on. If Archi is referring you to me I don't hold out a great amount of hope but you never know.

Cheers,

Wo0zy
Hi WoOzy, thanks for your help.


First, I try :
E2 1D 00 70 51 D0 1E 20 70 30 55 00 00 00 00 00 00 1E => 800x600 max
C4 1D 00 98 51 00 22 30 30 70 13 00 00 00 00 00 00 1E => VGA don't work (it's my laptop in 800x600 and return to normal resolution 1400x900)
01 1D 00 70 51 D0 1E 20 70 30 55 00 00 00 00 00 00 1E => 800x600 max

(it's curious that the max is 800x600, when i can have 1024x768 normaly)

Secondly, I ask on a forum if someone can have the edid with MonInfo on 1280x720 with VGA, but it's the same result : any information about the projector.
So I try with Keystone = 0 , but no result.


Then I read my manual and I find :
img248.imageshack.us/img248/5799/ptax200am1.gif

I use xtiming.sourceforge.net/cgi-bin/xtiming.pl to generate modeline for WIDE720 but not result.

I don't understand...

Taz, the french depressed!

I don't know if the 1920x540 resolutions will work for you, but they're worth a try.

Damn going all the way to *540 reminds me of the scary VGA or was it called XGA times where everybody where happy about 640*480. But if *720 is helping me out here, then I can live with that.

One last try

8A 1B E0 70 41 BE 19 20 40 80 13 00 00 00 00 00 00 1E

This is calculated from settings posted on the Powerstrip forum for a similar TV to yours. It seems very different to the timings we've been trying but might as well give it a go.
