About 30 minutes ago I was on my computer fine. I had to step away and took a phone call, in that time my computer went to sleep mode.
When I got back and pressed the spacebar to wake it up, my middle AOC monitor, connected by DP. (144 hz G2460PF) wasn’t working. I tried plugging the cable out then back in and the amber light turned green, it said no signal and turned back off. Done a restart and tried to detect it but no luck.

Edit: I tried connecting it to a computer with VGA cable (using a VGA to HDMI adapter) and it works. But, that’s not ideal.

Another edit: my GPU has 2 Display Ports, both not working.
