3rd monitor blinking?
Never seen this before, started having this problem yesterday. Monitor turns on and displays fine for ~5 seconds before blinking like shown in the video. This is an old monitor and used as the 3rd in my setup. I tried updating my graphics drivers, different HDMI cable, different port on GPU, plug into motherboard, powering off/on the PC, powering off/on the monitor, shutting off and unplugging the power supply everything is plugged into, ctrl+win+shift+b graphics driver reset. Yesterday I swapped the monitor's power cable with a spare one I had laying around and it worked fine for the rest of the day but now it is blinking like this again. Any other ideas on what could be causing this/how to fix? Otherwise I guess its time for a new monitor.
