I can tell that my display is slightly fuzzy. But it's not as crisp as it should be. I can still play games fine and everything. I haven't switched resolutions or anything. Temperatures are fine. I've tried switching resolutions and going back but it still maintains a tiny blur of fuzz if you will.
