I'm having an issue with my new Dell U2713. When in a dark room, the display is showing signs of leakage on the lower corners. The lower left corner is reddish while the lower right corner is grey. (see pictures). At $700, I am quite disappointed, especially when the 3 years old Dell UltraSharp 2408WFP next to it looks better in terms of blacks.

These pictures were taken in the dark at a little more than 2 feet from the screen.

 Is there a real problem or is that typical from large displays?
