Hey party people, I've come across something that is terribly annoying with my cinema display, it's connected to my mac book pro and is a 20" version (not one of those fancy new ones the ones before). It looks like it's got like an image stuck on it and when I'm retouching images it's bugging the crap out of me!. Does anybody have any recommendations to sort this? I've taken a picture both on my phone and a screen capture. Cheers in advance!
