It transcends CRU, as one would expect, as I am not seeing all the resolution options that would normally be offered in NVCP. I do have a laptop here with Quadro drivers so I will see how that responds to the set (S90C 77") later and report back if the situation improves there. I don't think Samsung's TV division and Nvidia have established compatibility certification so it might be difficult to get either side to look into the matter.

You spent enough time helping on this already so I joined your Patreon (long overdue) and kicked you over enough for a round or two.

Appears to read the EDID and the extension block (CTA) shows up but it seems changes made there have no impact.

Does deleting the "Extension override" data block make a difference? What about if you leave the data block and add two additional extension blocks?

This whole mess is caused by the HDMI 2.1 standard adding an extension override data block to override the extension block count, so the extension block count is both one and three at the same time, depending on whether the GPU's driver supports the data block or not. Then on top of that, NVIDIA implemented the data block by modifying the reported EDID in strange ways. This issue mainly affects RTX 3000/4000-series GPUs, which I don't have, so I can't test this myself.

I'm working on a better solution to read all the extension blocks, but every solution has some problem. If I implement the extension override data block as the HDMI 2.1 standard intends, older GPUs will ignore additional extension blocks added by the user. If I delete the data block, newer GPUs will ignore the additional extension blocks that exist by default. If I change the main extension block count, older GPUs won't be able to read the additional extension blocks anyway, so that would cause the "Default extension block" problem with older NVIDIA GPUs.

That leaves me with two solutions:

1. Create a separate extension block list in the CTA-861 extension block for additional extension blocks that newer GPUs will read but older GPUs will ignore. This would best represent what's actually happening, but this would definitely confuse people and would be annoying to implement.

2. Delete the extension override data block and change the main extension block count if the additional extension blocks are readable. That would be the simplest to implement and should work with all GPUs, but this would change how the EDID is represented and hides what's actually happening. It also technically violates the EDID 1.3 standard without an extension block map, but GPU drivers don't seem to care about this anyway.

I feel like the HDMI Forum didn't take into account what kind of impact this data block would have. I'm not the only one scratching my head trying to figure out the best way to implement this.

It's in the data block list that you edited.

This is what I can see...I do not thing there are any Extension override...furthermore if I check the other types, they are empty.

Hello,

I have an problem with this Utility. Whenever i add "1080x1080" for example and then apply that resolution in a game i get an Blackscreen everytime, any fix for that?

Operating system: Windows 11

Hey guys, after CRU reset I cant see higher resolutions anymore on an RTX 3080. Details:

I tried to mess with an EDID for my Monitor to use with 3D Vision, yet not the way I liked it but it's getting there. Anyway, wanted to reset (reset-all.exe,restart64.exe) like I did before 2 times but display wouldnt come back online.
Restarted, during post boot/win load it would show screen but not onymore on bootmanager. After some tries I did hook up an old monitor with a picture but to my surprise there was no FullHD+ Resolution available anymore (see attach - also in nv cp not more than 720p). Weird that the newer one cant display that but nvm.
So i tried different ports/cables, uninstall-DDU-reinstall drivers, custom resolution of 1080p would give blank screen, win sfc and dism but nothing will restore those resolutions. Any Idea what's going on?

It's literally the first item in the data block list.

Just in game or on the desktop too? If the monitor doesn't support the resolution, you'll have to enable GPU scaling.

Sometimes the driver can crash while restarting and the driver stays disabled after rebooting, but that normally wouldn't cause a blank screen because the basic display driver will load just like in safe mode until you restart the driver again. Usually if DDU doesn't help, that indicates a hardware problem. It sounds like the GPU might be faulty unless both monitors somehow have issues. The issue with the old monitor almost looks like it can't read the EDID. While connected to the old monitor, post a screen shot of what's listed in Device Manager under display adapters and monitors. With the newer monitor, try unplugging the monitor's power for a minute to reset it just in case the firmware glitched. If that doesn't help, does the newer monitor work if you boot Windows in safe mode? What about if you boot from a Windows install drive?

I have already enabled GPU scaling in the AMD display settings and i get the blackscreen whenever i apply my new res in the ingame settings

You are right...I am probably blind...sorry...deleted and started after both restart.exe and restart64.exe, nothing has been changed, unfortunatelly. Just to be sure, for a 64bit os I have to use only restart64, is it correct?
I have an rtx 3090...
