I purchased and installed a Sapphire Dual-X R9 270X card. It drives three displays on my PC: a 1920x1200 display, a 2560x1600 display and a 4096x2160 display. All displays worked as expected after loading the windows drivers. When I installed Catalyst, my 4k display switched to monochrome and I have no idea hoe to switch it back to color. Any ideas?
