I run a r290x crossfire setup with a Sony x700d 4k TV. Since I updated to the Windows 10 Creators Update and 17.4.3 1080p resolution in games is washed out. Switching back and forth between 4k and 1080p in game shows the difference in colour. I've double checked my TV and it's set to full HDMI input and the settings don't change when the inputted resolution changes. The only thing that has changed is the drivers. Is there a way to force full colour range from the AMD settings? I've searched through their settings and can't find anything.
