Hi, I have:
And I have issues with image quality. Sometimes, for no apparent reason image gets like "pale" solution is to go to Radeon Software, click display, click Pixel format, and change it to LimitedRGB and then return it to Full RGB, some times it is other way around to get god image. Issue is that Radeon software is so slow and laggy it takes few minutes to do this procedure, but this should not be happening anyway. It is not the way it should be happening. You can see difference in screen shots down below, so it is not monitor issue.
