Hey AMD Community, 

 

I read these threads:

My monitor supports 10bit but cannot be enabled in Radeon setting 

How do you get the WX 5100 to use 10-bit? 

Windows 10 RGB444 4K 60hz 10bits mode issue 

 

...but I still couldn't get 10-bit 4k working on my AOC U2777PQU.

 

I'm running the latest 20.4.1 Radeon Software, but I tried 19.12.1 and 20.2.2 with the same results. I can select 10-bit in the software, but when I activate it, it automatically reverts to 8-bit. I tried 30Hz, full and limited RGB, different YCbCr settings, same story. My operating system is Win10 Pro 1909. I have the B450 Aorus M board, it only has a single HDMI, no DP, so there's that.

 

I saw in the previous threads that cru data can be useful, so here it is:

The only thing I can't verify is the HDMI cable. I use the factory cable, and AOC doesn't provide any specific info about it. I have other cables, but they are older than 2013 (HDMI 2.0 dates back to that year), so I assume there's no point in trying them.

 

Any advice would be appreciated. Thank you.
