So I'm having a very frustrating issue now where my pixel format setting in Catalyst spontaneously changes. It needs to be on RGB Full, but about every day or two I noticed colors in videos are strange. Catalyst claims it's still in RGB Full, but when I change to something other than RGB Full and then change back to RGB Full, the colors look normal again.
Annoyingly, I can't seem to figure out what triggers the issue. Resetting my PC, remote desktop, opening and closing Plex, turning the TV off and on, and turning my receiver off and on do not seem to trigger the pixel format change. It seems to happen randomly.
I use Plex with DXVA on. With DXVA off, colors always look correct (so maybe Plex's handling of DXVA could be at fault?). I'm running the latest version of catalyst (12.1).
