EDID Overrides to solve bitstreaming issues for ATI 5xxx's - Page 10

Oops that is the video driver, I reinstalled 10.2 but it did not replace the realtek driver. I manually removed it and re-installed the ATI audio driver, it is now working.

Ah, I was starting to think I had the wrong driver loaded.

Probably a stupid question but what does the display device have to do with the AVR? Maybe I am misunderstanding what this mod is supposed to accomplish.

I am getting an 5450 tomorrow and will be trying to play truehd movies through HDMI to my Denon 2310CI. What does it matter what display you have?

Edit: Video will be output through my 4870x2 and audio through the 5450 btw.

The mod is to fix an issue where Windows is not able to tell that your AVR can decode HD audio so you can bitstream. The issue is that the EDID contains data about the video capabilities of your monitor as well as the audio capabilites.

The computer will "see" the AVR as a monitor with really good audio support since HDMI audio is piggybacked onto a video carrier signal. When you have a TV/Monitor connected to the AVR, the video support information of the TV gets passed and the AVR injects the audio support information. So the mods for various TVs have been to preserve the modes and timing information for those TVs.

Since you are connecting your TV to your 4870x2 and not to the AVR, you don't need to worry about the video timings and any Denon combination would work for you. All you will care about is the audio portion of the EDID. Your Denon will show up as a second monitor on your computer but you can just ignore it (ie: don't clone or extend the desktop).

You should attempt to bitstream without an override first to determine if you really need one (most likely you do though).

Tulli: Here you go. I can see that you already have an updated sample but mine is a European model and uses a different firmware.

BTW I tested that I could play both formats before capturing

I need help too

Hope i did the Getedid thing right.

Tulli (and others)-

I hoped it wouldn't come to this, but I just cannot get my new 5450 to work. When I look under the "supported formats" tab I see only the basic three windows options. DTS, Dolby, and WMA; none of the ones I want to see!

So here's my setup:

HTPC with PowerColor 5450 -> HDMI 1.3a cable from monoprice -> DENON3310CI -> HDMI to DVI cable from monoprice -> SONY KF50XBR800 720p rear projection HDTV

This TV is rather old and I'm wondering if it is the source of all these problems as it has been rather poor in the past in regard to timings and HDCP on some older NVIDIA cards.

I've done multiple installs and uninstalls of 10.2 Catalyst and Realtek HDMI 2.42 mixed with driversweeps in safe mode. The current state is a fresh install of Vista SP2 with Catalyst 10.2 and pretty much nothing else but windows updates installed. Still no go.

I have two guesses as to the problem:
1 - don't know if this makes sense, but could that HDMI->DVI cable be a problem? Does it make sense to have a HDMI1.3a HDMI->DVI cable? I don't think so, but...
2 - That Sony's EDID is blocking almost everything from getting past along.

Anyway, any help would be greatly appreciated.

OMG This is getting surreal

Will version 2.4 of asset manager work with the 5000 series?

Understood, but, with bitstreaming it's pretty binary. It either works or it doesn't.

Ehhh...ok, what does this mean? Will we need to continue to use the existing override? A new override is needed/better? Different workaround? Still, all the set-top boxes work fine, so I vote that ATI is way too picky...

Thanks for your help

OK Lets try again

Here is a realtime capture with moninfo. Hope fully the bin file is ok for your to work with.

Ok, very good explanation!

You answer raised an eyebrow for me though. The reason I don't have my 4870x2 connected to the receiver (it's connected directly to the TV) is because when I connect it to the receiver I get very noticeable mouse lag. In CCC, the Denon IS recognized as a monitor and so maybe this thread also pertains to the 4xxx line (since it's been determined this is a receiver problem actually).

Do you think the EDID override might help the mouse lag? If so, should I just try the (*) Samsung LN-S4095D - DENON AVR988 override first?
Edit: Or should I just capture the EDID and post it here?

Btw, I am using a Samsung LN52A750 and Denon 2310CI.

Sorry for all the questions, this is all new to me.

I really appreciate all the help that is being volunteered here!

Edit: Also, I am not getting the third option in PowerDVD9.

If we can replicate my registry settings for everyone, this might be a nicer solution to fixing the problem! I can pretty much guarantee that the actual inf file is no longer present.

I don't know if I'm happy to hear this or not. On one hand, it means that the ATI driver API is returning the EDID override if it exist and reading it realtime if it doesn't. This means that GetEDID will show exactly what the driver is seeing and processing. On the other hand, it means that there is no method in the driver to capture the realtime EDID if there is an override present.

I'll look into this further but it may have to be after I get back from vacation.

The status of my system is even more interesting than it first appears.

With Tulli's override in place, I could play the various HD audio formats fine. Unfortunately it played havoc with my two screens Kuro / JVC PJ

The EDID was taken from the Kuro and forced upon the JVS due to being unable to load two different display overrides. After removing the override & performing a complete driver clean up, I now have full HD audio capability and my displays are now recognised independently of each other

I have no idea how it's fixed but I am a happy camper

Beamer, can you export the following key for me and zip and attach the reg file:
Edit: Tulli is ahead of me.

Ok, will do as soon as I get back home.

Does it matter if I generate them using the 4870x2? The reason being, if this display timing fix works, then I won't bother opening the 5450. If it doesn't work, I will install the 5450 and the override will already be in place.

With that said, is there a proper way to undo the override to test the 5450 clean or should I just plug it in with the override already in place?

There is another function in the API that will grab the DDC info which may be what I need to use. I'm going to look into it.


I agree. This is still pretty useful so I'm not going to scrap that function.

Here you go, attached registry entries

The 4870x2 will be fine. The data captured will be the same regardless of which card you use.


I can't remember if the override stays in place if you switch video cards. It's pretty painless to uninstall the override though. Beamer's case seems to be the exception but we can easily clear his override too. We're just not doing it at this time since it's working for him.
