I got this problem about 1 week ago. When I started my PC there was a black bar on the right side on the screen. I tried to change Display settings in the Radeon Settings, but this didn't worked. When I launch any game the black bar dissapears. I am using AMD Radeon R7 360 Series. Any help?
I actually have same problem with my Samsung C27FG70 monitor which is connected via DisplayPort. There is about 2mm wide black bar on the right side of the screen.
