I'm getting some strange colouring (see vertical lines in the photo) on my 2nd monitor after a recent power outage. It's an old AOC 2236, and running off my onboard gpu. I also have my main display running off a GTX 1060.
It displays most colours fine, but it seems to be missing some of the darker colours and instead just shows off colour lines.
So far I have tried deleting the onboard drivers and reinstalling. I tried deleting the AOC monitor drivers and reinstalling. I switched it to the other graphics card port which runs my main monitor (which is fine) and it still has these problems. I'm fairly certain is a monitor issue and not software now, though it did seem to correct itself for a time earlier.
Any suggestions on anything that may be the cause, and a possible solution? So far I'm thinking either the monitor's psu, or maybe the cable connecting it to the gpu. Also what do I call this kind of problem? Half the battle is in trying to describe it.
