Adrenaline has problem scaling to fill the screen on my AOC 4k monitor. When i drop below 2160p to say 1440p or 1080p the result is the windows screen will become smaller and not fill all the available space on the monitor. The result is black bars on all 4 sides of the window. This didn't happen with previous drivers. Oddly enough i am able to successfully lower the resolution from within games (filling the entire screen) however once i exit the game it returns to the way it was. As of now only 2160p is the only res that full fills the screen. I am using windows 10 fall creators update and the monitor is connected to an R9 390 via display port. Turning gpu scaling from within adrenaline has no effect.
