I just bought a used 30" ACD today, and if the screen is on and displaying black, I can see hundreds of very faint stuck green pixels. I searched this forum and found others reporting similar experiences. Does Apple ever replace/repair hardware that isn't under a warranty? There are Hundreds of the little green guys. But on the other hand... you can't ever see any of them unless you make the screen go dark and look Really close. So... naturally there are scores of satisfied customers who have no idea that anything is "wrong" with their screen... and that leads me to a question. Can this be considered a defect? If the screen looks and functions perfectly for all normal use (i.e. not putting your face up to the screen like an idiot), isn't anything else going on in the screen irrelevant then? What needs to be there to make the experience what it's supposed to be is there... and there are likely thousands of people with screens just like this who have no idea and are perfectly happy. What would you do in my situation? I could always just sell it.. I got a great deal on it, I could make my money back for sure, likely plus some.
