Grey "bleeding" pixels problem

I have some "dead" pixels (bunched together in two different spots) on my monitor, although they don't really appear to be dead per say. On a white background, under a magnifying glass, they look like they're bleeding, only half or so of the pixels are grey and the rest are white.

This monitor is only a few months old. Can someone tell me what's wrong?

It's definitely not dirt on the screen itself, but I guess it could be on the inside. The room it's in is very dusty, no matter how clean I try to keep it. Thanks for the tip.
