I just upgraded to a Sapphire R9 390 (from an HD6870).
I have a Lenovo Pro2840m monitor and am connecting it over DisplayPort.
My problem is that the option to select Limited RGB appears to be missing. It's available with HDMI, which I would use, however I need to use DisplayPort for 4k at 60hz.
Currently the colors are washed out, like when I had Full RGB selected on HDMI.
Is there anyway to select Limited RGB with DisplayPort?
