Black border around Samsung U28D590D monitor at 1440p

[Froze22]

Hello

My second monitor is a Samsung U28D590D set to extend my first monitor. The max resolution my GPU (GT 750m) can run is 2560x1440. When I set the resolution to 2560x1440, my desktop has thick black borders around the wallpaper. (See attached screenshot.) If I set the resolution to 1080p, the desktop is fine. Any resolutions in between also have borders. I can still right click on the black border section of the desktop, so the resolution is being applied, it's just the wallpaper that isn't scaling. Any ideas how to fix this?

Hi try adjusting the scaling in the graphics control panel could be called over or under scanning.
