Hi Tulli
The EDID override did not help. One thing that has changed since you provided the .inf is that I am now NOT using a separate SPDIF for audio. I was able to find the ATI HDMI adaptor that converts DVI to full HDMI.

Do I need to edit the .inf because of that? I am getting audio errors after turning monitor off/on (in addition to resolution issues). Restarting media center fixes both.

No change needed. Now, make sure to apply the EDID override to the correct GenericPnP monitor (or apply it to every GenericPnP monitor - with Denon on and off), and reboot. Double check on the Monitor tabs in Device Manager.

If problem persists remove any grayed-out monitor drivers (see section 4 from link in my sg.) and try again. It should work.

Thanks Tulli.
There was only one monitor and it was GenericPnP. I updated it. I did not try with Integra processor turned off (didn't think I needed to). So I will try that tonight. Will also try instructions in your sig.

Well, after trying a couple more things it seems like it is working.
- Applied the override with Integra OFF as well.
- Did not find any hidden monitor other than GenericPnP which seemed to be hanging around in addition to the new Overrides. Removed it but it came back after reboot.
- Noticed the second monitor (dual mon video card) was enabled in the screen resolution screen. Removed (disabled) it. But it keeps coming back after reboot.
- Installed latest driver for ATI vid card.
- Installed latest Ceton driver.

After doing all of above and various reboots and system rollbacks (dont ask me) I have somehow arrived in a state that the EDID Override is working.

YEAH !!!!!

The screen takes a while to show up but it eventually does. And also keeps the resolution. So thanks for all your help. Appreciate it.
PS: If I open the device manager and look at the monitor (EDID override driver) it has a yellow excalamation against it. It says something about another driver in memory and needing a reboot. Error Code 38. A reboot does not change that. But since it does not impact my use of the system I am ignoring it.

gday after searching a bit about my issue found this thread.

My setup.
GTX 480 -> VT20 -> SC-BTT755 (blu ray player with 5.1 output)

My panasonic VT20 hdmi audio only has stereo listed under playback devices.
Could a custom EDID override unlock other audio (AC3, DTS).


I used moninfo:

Hi EDID specialists!
I have a problem with my Asus EeePC EB1501 with Nvidia ION chipset.
My Setup
"1080p Video / AC3/DTS Sound": 1501 -> Nvidia Audio-> HDMI -> Sony LCD TV -> SPDIV -> Sony .

My LCD can passthrough DolbyDigital because I tested it with my xBox 360 and IPTV. But the EDID information of my LCD says something different.

Now I edited my EDID information and added 6 speakers and DTS support, make a inf file and installed it. But the nvdia driver only show 6 speakers and no DTS support(picture). i also get no dolby digital - only 2 channel lpcm.

Can you give me some tips how to edid my edid-file to get DTS/DD support. otherwise i would have to convert my dts-movies to ac3 sound and stream it via xbox360 mediacenter xtender .

Thanks 4 your help!
Stefan

By working on your edid_standard file I added a simple 2-LPCM + AC3 + DTS audio block, and same Speakers descriptor (mod atached).

Comparing it with your edid_overwrite, found:

- An additional MPEG1 SAD (don't know if it matters, but it shouldn't be there anyway).
- Different VSDB (should affect video only).
- No VCDB (should affect video only too).

So I see no possible problem except the MPEG1 SAD.

I just got the HDMI Detective because I had HDMI handshake problems with my HTPC -> AVR (Denon AVR-1910) -> Panasonic plasma TV setup from time to time.
Been testing the Detective a bit and it seems to have resolved my problems (can't say for sure yet since the problem didn't occur that often...).

Before I bought it I think I read somewhere (don't remember where, sorry), that this device would also get rid of the short audio dropout that occurs when you turn off the TV. Didn't work for me. While not a huge problem, it would be nice to keep the music playing while you turn off the TV, instead of losing ~1 sec of audio.
Anyway, is this even possible? Maybe I just misinterpreted something and everything's fine this way.


Please someone let me know, thanks!

Hi Tulli,

I have an interesting problem with my setup. This all materialized after I upgraded from an ATI 5750 to a GT 430.

I have the HTPC going to a DVDO iScan Duo then that splits the audio to a Marantz AV7005 and the video to a Pioneer PDP 6010 plasma.

I couldn't get HD Audio to bitstream, and not realizing the problem was the lacking TMT3 hotfix for Nvidia drivers, I kept swapping EDID override files that I knew worked with the ATI (Pioneer/Denon and a Samsung/Onkyo). The problem is that since I installed and uninstalled the EDID override files, when I reuse them, the Monitor gets overridden from "Generic PNP" to whatever is in the EDID files, but the Audio Device continues to show "iScan Duo". I've tried uninstalling the Monitor driver and telling Windows to "delete the driver files," but to no effect. I've even reinstalled the Nvidia drivers using the "clean install" method and can't get the audio device to be overridden.

So what I tried was to go straight from my HTPC to Marantz to TV, and Windows recognizes the monitor as "Generic PNP" and the audio device shows up correctly as "Marantz AV." In this setup everything works great: Audio SD and HD bitstreaming, 24p framerate, etc.

A couple of questions:
1) Do you know of a way to freeze the Marantz profile and tell Windows not to update its devices so I can reroute everything without Windows going back to iScan Duo?
2) How can I get past the audio device not updating with the EDID override file when I update the driver in the Monitor section? I couldn't find anything where I could change the audio device with an EDID override file.

Thanks in advance.

Well, depends on where you have it hooked. The HDMI detective will obviously keep alive only the connection of the HDMI device attached to it. If it is placed between the HTPC and the AVR then switching on/off the TV will be detected by the AVR and passed to the HTPC. If placed between the AVR and the TV then there will be no on/off switching detection regarding the TV (but not the AVR, of course).

Try cleaning up registry leftovers (see section 4 from link in my sig.).

An indirect way of getting rid of the overrides is to keep installing one general .inf file, any one; but then choose from the ones already installed in Windows, then uninstall with the "delete files" option; repeat same process until no EDID override is presented as an available option by Windows driver install dialog.

Oh I see, thanks!

If I'd move the detective from between HTPC & AVR to between AVR & TV I guess I would still encounter the handshake issues I used to have though? I'm using a HD5750 btw. and often send AVR and TV into standby while the HTPC's running.

Tulli,

I'm totally impressed at how much you are helping everybody here. Thanks! It's a great service to the community.

Are the type of mods that you are doing something that many users could do if they just had some basic documentation? Or is the type of thing that is so complicated that most of us couldn't handle it without specialized training?

I ask because if the mods are relatively simple I think it would be interesting if, whenever you get the time, you put together some more detailed documentation about how you actually do the mods. I've looked through your EDID Override link below your profile, for example, and it doesn't quite go into those details.

I for one would be fascinated to learn a little more, and it might end up saving you some work long term!

I tried to write down a guide, but it was getting so complicated that I gave up half-way.

The problem lies basically in the many different problems with EDID detection/parsing. Of course we have video issues and audio issues. And modding procedure in each case is different. Here's a list of the types of mods:
  • Merging of Display Device and AVR/AVP EDIDs: mod consists in replacing the Audio Block and Speakers Allocation Block of the Display Device with the AVR's. But there are variants:

    - Display Device has no Extension Block (e.g a Monitor): simply add the full extension block of the AVR.

    - Display Device has no Speakers Allocation Block.

    - Audio Block has to be modded first:

    - Change 6-LPCM to 8-LPCM (ATI parsing bug)

    - Remove unnecessary SADs (e.g, see recent case above: MPEG SADs)

    - Correct TrueHD descriptors (ATI parsing bug, ... , fixed by ATI)

    - Replace split Audio Blocks (e.g Sony & HK AVRs)

    - Add AC3 & DTS SADs to 2-LPCM-only audio blocks.

  • Replace main Video Detailed Descriptor.

    - With another descriptor from the same EDID.

    - With PowerStrip custom timings.

  • Change Vendor Specific Data Block (YCC->RGB).

Here's a general description of the editing process, which is a bit cumbersome indeed.

Maybe you get a better idea now of why I had to quit writing a guide that would become either too difficult, or too long.

If you can find a way out of this mess, please let me know. I'll be ready to answer any questions. Thanks!


=================================================

UPDATE 2/7/2011

Here's a general procedure for merging the AVR Audio block into the TV EDID.

And here's is a description of procedure for inserting Powestrip custom resolution in the EDID. Generation of Hex codes is done with Phoenix EDID Designer or Delcast E-EDID Editor. Easiest way to insert these hex codes is by editing the EDID (e.g. in .inf file) with Notepad or Wordpad.

The first thing to do is read up on and learn the structure of EDID data: http://en.wikipedia.org/wiki/Extende....3_data_format

Tulli and I did that until we were crosseyed and dreaming in 128 byte blocks.

Once we got a handle on that, we just tried various things with problematic EDIDs and eventually started narrowing down the issues. In the beginning, we just replaced bad extention blocks with a known good one. Through much trial and error, we finally discovered that the audio descriptors had to include certain data for HD audio bitstreaming. We also learned how to change the video parameters to fix other issues.

You can learn from our trials though and catch up quickly. Learn the spec (or at least be able to understand it) and then you can look at some of the "bad" EDIDs throughout the thread, and see what was done to fix them. The later fixes in the thread (or the ones in post one) will be the better ones. The earlier ones might be where we were still getting a handle on things.

Once you understand the spec though, things fall into place really quickly.

I think the key would be to make a two layered guide. The first page or layer would be simply a list of typical problems with links to the second layer, which would be specific guides to how to resolve only that problem. There could also be a link or two to general introductions to what's going on, the basic principles being applied, etc..

When a user has a problem with an EDID, usually they don't know anything about EDID's and how to modify them. They just know they have a problem with their monitor's settings, and that someone somewhere told them or they read to come here and get an EDID fix.

The advantage of a two layer approach like this would be that you would "keep it simple" for the ignorant end-user who just know what his problem is, and you would also keep it simple for you. You affront one problem at a time, starting with the most common or simple and working your way up. Each guide explains only one problem and solution, so they are kept relatively short.

That's my ideas on it anyway - you'll know far better if such a thing is really practical and possible or not. Thanks again!

Hi,

long time lurker here and now time for me to raise my hand in surrender and ask for assistance as I have no idea what else to try.

I have an HTPC (Asrock ION330HT)connected to a Yamaha v861 receiver via HDMI connected to my Sony 46X3100 TV (Australian equivalent of the Sony XBR4) via HDMI. For the life of me I cannot get my htpc nvidia drivers to see my Sony TV, nor will it show supported audio formats other than DD. Another issue is I cannot set display resolution to 1080/24p despite the TV supporting it (I know this b/c could play blu-rays on my ps3 using 1080p/24 - it shows up in the Tv display when the resolution changes).

Through various forums I have the moninfo data for the receiver and the TV (well, the XBR4) - can someone tell me if combining these will fix the issues and allow me to select 1080/24 as the resolution via my htpc? And if the answer is yes (as I hope it to be!) are you able to assist in putting the ovveride file together? I am really confused as to how this works, but this is my last resort!

many thanks,

Could work. The Sony EDID lacked an extension block so I simply merged base block from the Sony with extension block from the Yamaha.

thank you so much! I will try it out on the weekend and report back. Much appreciated.

Update: applied the new .inf file and doesn't appear to make a difference unfortunately. No change to audio formats supported in my nvidia control panel and still no native 1080/24p (but can set custom mode that sometimes works). Perhaps it's an nvidia driver issue - so not giving up hope yet - time to trowl through the nvidia forums....

Thanks all the same for your assistance - very much appreciated.

Hello,

I have a problem with my HTPC. I purchase an Asus 5670 1 Gb, and I can't config DTS HD or other HD format. I have an HDMI cable from Asus 5670 to AVR (Marantz SR5003), and output goes to Pio 5090H. In ATI HDMI Output, in speaker config I see 4, 5.1 y 7.1, but in Properties, I don't see DTS HD-MA or Dolby TrueHD modes, only DTS, Dolby and WMA (AVR supports HD modes).

I have Vista32, CCC 11.1 and HDMI is 1.3b. EDID problem?

Very Thanks.

- GPU: ATI HD6950 with last driver CCC v11.1
- S.O.: Windows 7 -32 bit

With the original ATI HDMI driver installed, in the window that show me the sample rates of the HDMI GPU, i can't see the 192 khz audio frequency. Why?? Without this frequency i can't bitstream audio, i'm gonna be crazy with this problem and i'm sure that the problem is a wrong EDID. Please can you help me? Thanks!

Could be a driver/OS. It's usually difficult to get bitstreaming of HD working in Vista. Also, TrueHD and DTS HD don't show up in audio properties in Vista.

Search in thread in my sig. for vista related issues. Other than that I suggest upgrading to Windows7.

Native resolution of that monitor is 1920x1200, right? A standard HDTV resolution (1080p/i, 720p) is required by the AVR to bitstream HD.

I tryed to use the option "enable GPU scaling" in ATI CCC and the image's proportion in 1920x1080 would be correct but the AVR can't send HD sound with this option enabled. Is there any solution?
