HP 23xi black border when using HDMI [SOLVED]

Select “Catalyst Pro Control Center”
Advanced -> ATI Catalyst Control Center -> Graphics -> Desktops & Displays
Please select a display. (Click the black downaward arrow in the corner of the display graphic) -> Configure

Click OK/Apply
For NVIDIA, disable under-scan
Right click on the desktop, select NVIDIA Control Panel
