I an having issues displaying 4k content using the rx480. I have no option to display 4096 x 2160 in the control center ( running most recent version). It does state that the max resolution of the monitor is 4096 x 2160 and 75 hertz. However, I can display 4096 x 2160 60 hertz through windows 10 preferences. The only issue is that when used through windows 10, I cannot change the overscan/underscan. Is there a way to fix this?
