Apple cinema display circles at bottom?
I recently bought a cinema display (old plastic) off ebay... it has small weird burn ins at the bottom or what looks like two burn ins of sorts. this was weird to me as lcd's don't burn in typically. any how i want to buy more of these displays but wish to know more about these burn ins to safe gaurd my future purchases. I don't care about this display but don't want to buy a 23 HD with it as it will be my main display. any help?
