AOC E2752VH 27" monitor has a dark shadowy spot. Doesn't look like a typical stuck pixel, more like a dirt smudge that won't go away. In fact, I originally thought it was just dirt, until I tried wiping it off and would not go away. It is about the size of a dirt smudge made by pressing a pinky on the screen. Everything that appears in the shadowy smudge appears darker. The spot is more visible in backgrounds that are all white/ all the same color. It is not noticeable in very dark or black backgrounds.

SOURCE: monitor color changed

Assuming you can rule out the PC and the cable (are the pins ok?) then it sounds like it needs component-level electrical troubleshooting.

There are 2 answers here. First is (bad) luck of the draw for your buddy and that would be that it just happened to go bad when you gave it to him. I could believe that except for the black spot. That leads me to believe he inadvertently pressed something in the spot and the pixels are now bad. This may have happened when he or even you were transporting it or as he was carrying it in.
The question I see is how do you resolve it? If you were lucky enough to have plugged it in prior to your coworker taking it, the onus would be on him/her. If not-and to avoid bad blood at work- you may want to refund a portion of the price. Sorry there is no clear cut answer here but in the future if you should do so again, let the purchaser see it al works beforehand.

SOURCE: my aoc lcd monitor appear full white screen

Most probably failure in the LCD controller IC in the lcd controller board. that no signal was sent out to the lcd driver ic thus you could only see white display on the screen. A replacement of LCD panel might be the solution. regards

SOURCE: I have black spots on my monitor screen that seem to multiplying.

I hate to say it, but that's fatal

The black dot will just grow until the rest of the screen fades.

It is pixels dieing in the monitor
