RE: Custom Resolution Utility (CRU)
Is there any reason to add missing Colorimetry if the EDID doesn't have them checked (for example, on my set, only BT.2020 cYCC and BT.2020 YCC are checked)?

RE: Custom Resolution Utility (CRU)
Is there a reason CRU doesn't allow me a custom resolution of 8k? As i want to benchmark/torture my 3090, but only got a 1440p monitor, so can't DSR to 8k which only 4k monitors can do.

RE: Custom Resolution Utility (CRU)
Why would the "Dolby video" option be grayed out in CRU under CTA-861 even if I'm connected to a Dolby Vision capable display?

I'm not aware of anything in Windows that uses that information.

Gray just means CRU doesn't have a way to edit it.

Doesn't allow in what way?

After making changes in CRU and rebooting, the whole "display" section is missing from the nvidia control panel.
Deleting any changed profile from CRU and rebooting restores the "display" section

I am currently on win11, with nvidia driver ver 496.49
That sounds like a driver bug. Export a file from CRU and post it here.

What's the difference between Exporting the EDID as .EXE and installing it versus just running restart64.exe after making changes?

Exporting an .exe file is meant to provide a way to easily deploy the EDID without needing CRU, and the .exe file can be used in batch files to automate installation. It also includes a vendor-specific method for older Intel GPUs that I can't easily incorporate into CRU because I don't have a way of determining which monitor is connected to which port number. The .exe file will install the same EDID on all instances of the same monitor, while CRU allows editing each monitor separately.

RE: Custom Resolution Utility (CRU)
Thanks so much, ToastyX! Another question if you don't mind...

I have been trying to re-establish LPCM 5.1/7.1 audio on Windows 11 with my TV. I used CRU to do the following:
(1) CTA-861 > Audio formats > LPCM > Max channels 8 (7.1).
(2) CTA-861 > Speaker setup > 7.1.

5.1/7.1 will show up under Windows 11 surround sound options, but it just reverts back to Stereo, so obviously this isn't sufficient.

Anyways, I was looking around for other solutions, and came across these instructions from Intel advising on how to add 5.1/7.1 audio to their NUCs and they recommended using CRU but in an indirect manner: https://www.intel.com/content/www/us/en/...l-nuc.html
They first recommended saving the EDID using Monitor Asset Manager, then editing the EDID with AW EDID Editor, saving the new EDID, importing the EDID into CRU, and then exporting the EDID from CRU as .EXE and installing the EDID. Why do they recommend using Monitor Asset Manager and AW EDID Editor when CRU can edit the same things, or am I missing something?

All you need are the audio formats and HDMI data blocks. You don't even need the speaker data block. I don't know why they are complicating the steps with three different programs, but their instructions don't include the HDMI data block, so that can't possibly work.
