I did contact dell support, and a replacement is being sent. Looks like something with the backlight is going bad. The top left corner gets to hot and starts to turn yellow. So hot even a spot on the corner stops responding and turns dark. I did a little test, I got a fan and had it blow at the screen for a bit. The corner went back to normal.
Out of all the lcd's I've owned, I've never had one that got to hot.. This is odd. I wonder how this happens. If anyone has an answer, I'm all ears.
