Black bars on screen

[PatrickRatzow]

I used to run at 1440x900 but today I got myself a new screen that is 1920x1080 but for some reason it does have black bars even though its running in its native resolution

I installed the newest drivers (14.12)

GPU: R9 280X
Monitor: AOC E2460SH

Seems to not have black bars in a 16:10 aspect ratio even though the screen is 16:9. Works fine in 1440x900 or 1680x1050
