Whenever I set my refresh rate to 144hz the display messes up and doesn’t cover the whole screen yet the resolution is still 1920x1080 but when it is 60hz the display is fine, any fixes?
 
First thing's first.

Has it ever worked on the current setup? If no, the first thing I'd check is the cable and try another one. That card usually comes with all 3 ports, DVI, HDMI, Displayport, so try them all.
