When plugging in my monitor, it flickers on and off (usually for about 15 minutes) before it finally starts up. It sometimes flashes black and green, and when it stops flickering, it works perfectly fine. I have two other monitors, one much older and one much newer, and I have no problems with them. I've tried multiple cords and reinstalling my drivers, same result.

Are you using enhanced display features, like HDR or Gsync/Freesync?

Just to be sure that I understand your post: you unplug the monitor when not in use - correct?

If so what is the reason for doing so: power service problems, brownouts, blackouts, surges, etc,?

If you leave the monitor continually plugged in do the flashes and flickering stop?

You mentioned reinstalling drivers: do you mean GPU drivers or actual drivers for the monitor?

My power supply is the EVGA SuperNOVA 750 G3. I'm not using any enhanced display features, and I unplug my monitor because it sometimes flickers when not in use, which is distracting (I only ever use as a secondary monitor). It even does it when it's the only monitor plugged in and in safe mode. Leaving it plugged it makes no difference. As for the drivers, I reinstalled the GPU drivers and the monitor drivers.
