I would like to use 10 bit color on my new Dell U3214Q monitor, but so far am having absolutely no luck.
I am driving the monitor with a FirePro W9000 card, and have tried the card in two different systems, one Windows 7 x64 and the other Windows 8.1 x64. Driver version is 13.35.1012 (the latest at this time).
In all cases, enabling 10 bit color in the AMD control panel leads to a black screen on the next startup. If I connect a second monitor (a 24" 8bit monitor), then I see a desktop on that monitor.
I have tried DisplayPort 1.1a and DisplayPort 1.2 settings on the monitor and neither of these help.
Has anyone actually got 10 bit mode to work with this monitor?
In reading the forums, there is a lot of talk about monitor firmware revisions. How do I check which firmware revision that my monitor has?
