Why does my display go blank when using a KVM Switch?

Question asked by snowengineer on Jul 8, 2020


Describe your issue:

I have recently installed a PWAY two port HDMI KVM switch for easily switching peripherals between my work laptop and my home desktop computer. The mouse and keyboard switch correctly, but when switching to the desktop PC the display is blank. When I restart the computer the BIOS screen comes up followed by the Windows loading icon, which is then followed by a blank screen.


This appears to be a AMD driver issue as shown by a few other questions on the community forum. Any help would be greatly appreciated!
