Custom Resolution Utility (CRU)

The CEA-861 standard defines the timing parameters for digital TV resolutions, so NVIDIA's driver probably lists any resolutions matching the standard in the "Ultra HD, HD, SD" section. 3840x2160 @ 60 Hz with "LCD standard" matches the CEA-861 standard. There might also be TV resolutions defined in the extension block that are included in the list.

I see. That makes sense, thanks for the explanation.

There are more detailed resolutions in the extension block.

I performed a clean installation of the most recent drivers (436.15), using DDU, and went through the entire process with CRU again, first collecting the TV's EDID with the GPU connected directly to that display.

The TV itself only has two "main" detailed resolutions: 3840x2160 @ 60Hz and 1360x768 @ 60.15Hz. There are a bunch of standard resolutions (all 1080p and below) and one extra resolution in the extension block, of 2560x1440 @ 119.997Hz.

Marked down the timings of the two resolutions that I wanted and added them as an override to the Denon AVR, with the GPU connected through that device. This is what they looked like:

3840x2160 @ 60Hz
2560x1440 @ 119.997Hz

This is what the DENON-AVRHD "display" now looks like in CRU. There are no detailed resolutions and also no space left in its extension block, so I couldn't change anything there.

I have some final questions:

1. Do my settings look right to you?

2. I still haven't added the 3200x1800 @ 60Hz resolution, because I don't know what to include as its timings, would you mind helping me with that?

3. The issue that I mentioned before, where the Nvidia color settings keep reverting to RGB/8 bpc, is still happening, even after a clean installation of new drivers. It started only after using CRU, is there a setting that I can change to fix that?
