I just bought a new gaming computer and monitor. They arrived today and I got it all set up. There is a square of blue pixels showing up in the lower left corner of the monitor. They don't flicker, the appear on both bright and dark screens (though harder to see on dark screens), and don't show up on screenshots. This is a monitor problem, right? It's technically a TV apparently (bought it while tired and apparently didn't read the listing enough, oops!) so does that make a difference?
