So I have an older gaming laptop which I always plug a BENQ G2225HD moniter in via VGA cable. Until now it has been fine, but for last few days I have been getting faint horizontal lines that flicker on the monitor, but not on the laptop. The strange part is when I dont have the laptop power plugged in there are no tears whatsoever. Seems to be a monitor issue since it doesn't show up on screen caps.
