custom resolution 4k 2160p60hz 4:2:0

[RLBURNSIDE]

I also own a DP 1.2a -> VGA / DVI / HDMI adapter, but I couldn't figure out how to get NVidia to show anything but a 32-bit desktop colour setting. I was hoping to find a way, with Windows Creator's update, to force 10-bit windows desktop all the time, without having to fall back on fullscreen exclusive mode.

I'd managed to run Alien Isolation in Deep Color mode, using DVI -> VGA and also HDMI and my DP->VGA adapter too, but I haven't really been able to confirm if it's actually delivering true 10-bit to my projector. I'm going to try some fullscreen DX test apps with a 10 10 10 2 swap chain (most are using this nowadays and the RAMDAC inside NVidia's cards has been 10-bit native for many years now, so it should work).

Anyway, for the 420 setting over HDMI, I'm gonna try it at 1080p24 and 1080p60 before I try 1080p120. I'll report back if I can make any of these work. Too bad about 96hz not working though, that's a bummer. It's also a bummer that 72 / 75hz results in skipped frames on this projector too. Even a 20% overclock seems worthwhile IMO. If I had access to the firmware source code I could probably do something (probably brick my projector haha).
