So i have a 22 inch samsung monitor plugged into a power strip which is plugged into a ups and when i plug in a subwoofer in the power strip the monitor either shows a red line in the middle or shuts off and turns on back again for a mere second, also sometimes happens when i turn on the room light off and on, i don't mind this but could it possibly hurt my system? drivers are all up to date and hdmi is plugged in pretty well so i wouldn't think that's the problem, this problem has different interractions when i plug in different things into the power strip.
