I've been able to confirm that the hardware as configured is able to output 5.1 audio. Here's what I did:

1) Installed VLC.
2) In the VLC preferences, I set the audio output to use "Win32 waveOut extension output" and checked the "Use S/PDIF when available" box even though I'm using HDMI.
3) Tested with the Dobly Aurora VOB file from here: http://www.digital-digest.com/movies/movie_index.php?type=dolby
3) VLC now outputs 5.1 audio from my computer (through the Radeon 7870 graphics card, via hdmi to the LG AVR, with video displaying via HDMI from the AVR to the Sony TV).

The problem is that Windows doesn't believe the attached devices do more than stereo, and I can't get games to output anything more than stereo. (This machine isn't an HTPC; it's a dedicated gaming machine.)

I'll keep searching for software solutions. At least I know all the hardware is working now. If there's nothing left to explore from the EDID override angle, I'll leave the thread here to keep it on topic. Thanks for your help Tulli.

No, 2 channels detection in windows for HDMI doesn't mean "stereo". It means the maximum bandwidth for uncompressed audio (LPCM, check clarification in my sig.) for S/PDIF. If you want 5.1 for games a DD live encoding audio card is required.

Thanks for the info! I'll start shopping for a sound card.

I apologize, but my problem is really starting to get to me, and my post may have gotten lost in this thread, so i'll ask one last time and if noone can help me, i'll not post again.
Also my apologies as this is about "disabling" transmission of sound over DVI/HDMI, not making it run better in surround sound(have a dedicated sound card for that)

My problem is simple, blurry text (especially red) as well as slight artifacts caused by either an incorrect EDID or a post processing effect done on my tv's end, either way it cannot be fixed by the drivers themselves, however on nividia cards i was able to edit a key in the registry to disable a specific function of the EDID that made the computer see that it could receive sound through the HDMI port, i cannot find the way to do this with amd drivers however.

Thus, my only hope is to edit the EDID to claim that my tv cannot receive audio over hdmi, preventing my pc from broadcasting sound over hdmi, this is the only way to make my TV run in PC mode with a digital signal, thus fixing the problem, if i cannot figure out a way, i will be forced to use VGA to prevent my eyes from being harmed.

Basically i'm asking for someone to help me disable the function in the EDID, i am sincerely sorry for asking again, but at this point i am desperate, please help if you can.

EDIT:something i noticed, if i select a "pc" resolution in CCC(1366x768 for instance), the blurring stops, but if i select 1920x1080p(my native res) or any other HDTV resolutions it blurs the text and messes up the color.

Try the attached EDID Override. It will force a DVI detection. Otherwise post the EDID and I'll have a look at it. Perhaps it would be enough to remove the extension block line from the .inf.

Samsung LN46A650 - DENON 988 (DVI).zip 1k .zip file

EDIT: Aren't those artifacts with red that you notice and the blurring of text due to 4:2:2 chroma subsampling? Of course this only affects the desktop, not movies. Does your TV have something like a "PC mode" that will give 4:4:4. IIRC this is the reason why I made this particular mod. An alternative for AMD is to use a DVI/HDMI cable. Of course pixel format in the driver must be set to RGB (4:4:4).

Thank you for your assistance.

Yes, the problem is due to chroma subsampling, unfortunately for whatever reason my tv does not allow me to set the tv to pc mode.
The EDID override didn't work, however the dvi to hdmi method did.

I'm not sure why i didn't try that before other than the fact that when i did it on my nvidia card it didn't work, you have my utmost gratitude.

Hello everyone.

I'm also facing a problem with my Denon receiver:
A couple weeks ago I had to replace my about 11 year old Kenwood receiver with a new Denon (the Kenwood literally bursted into fire). However, I'm unable to bitstream the HD sounds formats from my PC to the receiver.

The setup:
I'm running a "Palit Geforce GTX460 Sonic Platinum" connected via an "AmazonBasics HDMI Highspeed with Ethernet" cable to a Denon AVR-2113. The receiver again is connected via an "AmazonBasics HDMI/DVI" cable to my "Dell 2707WFPc" running at 1920x1200@60Hz (according to the OSD). I also have a second display, a "Dell 2405FPW", connected directly via DVI to the GTX460, also running at 1920x1200@60Hz.

What works:
Strangely I'm able to stream DTS, Dolby Digital and PCM Stereo sound up to 96kHz to the receiver without any problems.

What doesnt work:
DTS-HD or TrueHD.


Curious:
According to Windows everthing is running normal:


However, I dug a bit deeper and found something interesting. If I use Moninfo I get the following realtime information:

If I use EDID Manager or Moninfo and read the information from the registry, then the whole CE block with the supported audio formats is missing. Maybe thats normal, I dont know.

Ive attached both .bin Files (realtime and active registry). Maybe somebody can help me.

You must feed the Denon with a standard HDTV resolution (1920x1080) to get HD audio. Search through the thread in my sig. for more info.

The solution is to use separate connections, set the Denon to 1920x1080 in extended mode.

Hi Tulli,
thanks for the help. After unlocking rolleyes.gif the HD resolutions in the Nvidia Controlpanel and setting the 1080p@59Hz resolution, Windows showed up all audio formats. I've tested two BluRays and they worked perfectly.

My problem now is, both monitors run natively at 1920x1200, and since the GTX460 has only two RAMDACs I'm unable to operate the receiver as a third one.

So, DTS + Dolby Digital and 1200p
or
DTS-HD + Dolby TrueHD and "only" 1080p on one display.

I probably will stick with the first option until I get a new GPU with more RAMDACs. Sad, but I think I will miss the 120 lines more than a couple crisper sounds.
post #2770 of 3084
hello all,

i just got myself into some problem by buying a Nvidia equipped GPU.

its a win 7 OS laptop with GTX670m. after using the LD450 for a long time, i am used to a certain way the graphics will look. and boy do i feel weird, i can see things rather smeared onscreen. also i found a certain Win7 bug, by turning on or off the win7 aero "look", the LD450 seem to have shifted 1 line downwards. if i display a full 1 pixel border, the bottom border is LOST ! eek.gif ... out of trial and error ... and fully pixel populated when not in aero mode. (anyone see this effect before? i know im late into entering the win7 arena, i HATE win7)

previously i use a ATI 5770, no problems with 4:4:4 going into a LG LD450 (IPS)

i have been trying to match what others are doing and trying to find the files to edit (EDID method for win7 GTX670m), but i think i have confused myself.

i have a installer folder loaded by Nvidia driver, it has a file NV-disp.cat ... i think i am suppose to edit a xxx.inf.
(by adding this HKR,,OverrideEdidFlags0,%REG_BINARY%,1E,6D,01,00,00,00,FF,FF,04,00,00,00,7E,01,00)

how do i get to this file? i do not see it in the initial install folder. did i got the driver version wrong?

*edit
i got my hands on moninfo and saved a monitor.inf file, is this file editable to tell GPU to send 4:4:4? if so how does 1 do this (use that string above?)? and after this INF file is done, where does 1 save this or apply this?

Try the solution posted by "ManuelG" on this thread to force RGB levels.

Other than that you could try removing the "HKR,EDID_OVERRIDE,"1"," line in the captured .inf and override the EDID. This should fool the Nvidia drive into detecting the display device as a monitor.

yep thats the problem with ManuelG, there is not Nv-disp.INF file in the extract, the new file is now NV-disp.CAT

the chunk of INF text posted is a file generated by moninfo, so after i edit that, what do i do to get it into the system?
post #2773 of 3084
Of course there is. Run the install and let the program do the extraction. In my system with W8 it's in:

C:\NVIDIA\DisplayDriver\[Driver Version]\Win8_WinVista_Win7_64\English\Display.Driver

And it's nv_disp.inf

For instructions to install the EDID override see my sig.
post #2774 of 3084


as you can see, the only file is a xxx.cat

is that the same file i edit?

What I do is just running the driver install without proceeding after the first screen and the file nv_disp.inf is always there in the extracted dir. Perhaps a modded driver would do:

thank you very much !

as i returned to this thread to read the very nice help from all of you (and Tulli of cos)

i noticed the driver from Nvidia is now 320.xx ... guess what guys ... they included a YCBr444 option (under display -- adjust desktop color -- item 3 -- digital color format --> YCbCr 444)

i must be dreaming or Nvidia finally understand that we want to see pixel for pixel on our screens tongue.gif. i then tried this wall paper (http://www.planetb.net/~chrispy/8500ub/test_images/NEC_pattern_1.png) and all the letters are spot on no side swiping into other pixels.

man ... how many years did it take nvidia to do this? or am i just lucky this time? (or i missed that the previous driver already has this option? i didnt miss anything previously did i?)


*edit correction* i loaded a belle nuit PNG ... the magenta and cyan smears but white/black is perfect ... hmmmm something is still wrong? lol ... i shall try your file next

@Tulli

Damn, I got a audio problem after I connected a HDMI extender frown.gif
My system will not send 5.1 to my reciever when playing movies in xbmc

It look like windows dosent reconice it correct (no coded formats)
Tulli, Do you think you could look at my inf and see if you could make it 5.1 compatible?

hi tulli, i tried the INF. it kind of interferes with the dual display format. using the INF, in dual display mode it will kind of "garble" both displays. so i had to reverse the install. thanks anyway biggrin.gif (you wont happen to be able to do 1 for dual display would you tongue.gif) ?

and no, the YCBR444 function in the new nvidia driver is not the cure it seems. switching between the RGB/YCBr options which it provides has no effect on the display. and the driver has a bug, once you turn to YCBR under desktop mode, it refuses to change back to RGB mode LOL ! however if you change refresh rate to 50Hz, it will fixate at RGB and refuse to change to YCBR lol !!!

being new to windows7, i also discovered that the wallpaper function of win7 is not WYSIWYG, it compresses the files you give it for wallpapering. so i have to review the test patterns under a viewer instead of plain wall papering. stupid win7 and nvidia !

mmmm im kinda out of ideas how to proceed hahaha.

Try the hacked drivers from laptopvideo2go that I linked to. They should give you all the functionality of desktop drivers on a laptop.

thanks, while trying 2 version of INF. i found that win7 seems to be "fiddling" with the drivers. after a reboot, the driver reverted back to the original PnP instead of the LD450 EDID.

then i also ran into this

If it's just movies, i'd say don't bother with 4:4:4, as i have yet to see 4:4:4 content on blu-ray, dvd, or whatever(i could be wrong, though).

As for the fix itself, first you need "Phoenix EDID Designer".


Launch it, then "Tools" -> "Extract Registry EDID"." Look for your dispaly in the list, select it, then "Tools" -> "Byte Viewer".


This is that you're looking for(as an example) :




Write them down somewhere.


Now, launch regedit, "HKEY_LOCAL_MACHINE" -> "SYSTEM" -> "CurrentControlSet" -> "Control" -> "Video"


There should some keys, expand them and look for "0000" with many entries and your adapter name in it. Right click on that "0000" and "New Binary Value". Rename it to "OverrideEdidFlags0", then double click it and enter "* * * * 00 00 ff ff 04 00 00 00 7e 01 00", where "* * * *" are the four bytes you recovered with Phoenix EDID Designer.


Restart the computer. Now you'll have full 4:4:4, but no HDMI/DVI audio.



Very simple test : Open "Paint", fill the screen with black, take "Pencil" and make one red dot. Zoom in(max.). You'll tell right away if 4:4:4 is enabled or not.

Of course. It's an old trick with Nvidia: disabling audio will fool the driver into detecting the display as a monitor (4:4:4). A simpler solution is to remove the extension block (second line of hex codes) from the captured .inf file and override the EDID.

But this is not your issue, is it? (To get 4:4:4) Your problem is getting RGB black levels, as you did with the AMD card, right?

It can also be solved with a custom resolution. Try that without changing the video timings.

mmm i think it could be that the driver is still seeing the audio thingy ... it just keeps on detecting the audio. bah !

the laptop driver doesnt see 670m ... weird. the drivers available could be too old for 670m i think (year 2008 if sort by win7 64bit)

the sad LD450 which i thought was doing 4:4:4 until i spotted a magenta smear


the adjacent LCD which is 4:4:4



its not about the black levels, its the pixel, its not 1:1. but when i try a black and white image its 1:1 ... it is very weird ... the non whites are smearing esp red and blue

i am assuming what i think is the error here ...

the RGB being sent over is still 16-235 and not 0-255. the EDID hack has killed the audio ... so now how do i ask the driver to show me 0-255?
post #2788 of 3084
If it worked the desktop should be at 0-255. Check Digital Color Format and Content type under "Adjust desktop color settings".
post #2789 of 3084
im pretty sure they are not, i managed to switch back to my old ATI ... its a terrible sight on the Nvidia ... dead give away ... LOL ...

as you can see the above 1st pic, the smearing (the 2nd/3rd pic are not of the 670m output)[IMG

This 1 is the output from ATI into the LD450

clean red and cyan dots

under item 3, digital color format etc ... there is no change whether i use RGB/YCBr mode.

is there something i can try on regedit? or is there something else to force a 4:4:4 mode in the EDID codes? (other than the killing of the audio stream) ... or something to kill off the HDCP?

i even have a cheap display port to DVI converter, but it does the same thing. i wonder if there is such a thing that a active DP will make a difference? buffered active DVI so that HDCP doesnt tell Nvidia that it is a TV.? maybe? lol
