I've tried choosing the correct source on the monitor multiple times and it has no effect. I have also unplugged and replugged the monitors and PCs wires which hasn't changed anything.
So, last night my PC was working fine then when I go to turn it on today it doesn't display anything on the monitor. I have been able to connect Bluetooth headphones to the PC and can hear my wallpaper playing music but the monitor refuses to display anything.
Any ideas on how to fix this?
