@lukestarkiller - I think you are just seeing a reflection here. The coatings on the glass which are designed to reduce reflections can alter the color of the reflected light. Try this, place your system and your self so you see the issue. Now without moving your system power it off or if you have it setup slide the mouse pointer into the active corner which puts the screen into sleep mode. Now step back to the exact same place do you still see the it?
