So I have my PS3 running at 1080p and it normally looks crisp, bright and lovely. But for some reason when I switched it on the other day the picture looked very murky, what I mean by this is that it looked noticably darker and slightly blurrier. At first I thought it had dropped into SD but it said it was still showing at 1080p. The resolution still looks fairly good but the dull colours is very noticable especially when watching blu-rays. I'm pretty much a n00b when it comes to settings and stuff so if anyone can help it would be greatly appreciated, thanks for reading.
