Well, I've joined the ranks of having a dead pixel. As it's black and not an actual color, I am guessing that it's dead rather than stuck. I tried the flashing video just in case, but that didn't work. The iMac is just about a week old. I've been reading about people who've had similar problems, and I don't see any consistency in outcomes of what happens when they try to repair/return it. Some have had >1 dead pixels on arrival and their Apple store wouldn't let them return. Some others have had even just 1 dead pixel anytime within the 14 day return grace period and they were able to replace their machine no problem (I'm assuming they also had to pay a restocking fee). Some people say that you can only return if you have >5 dead pixels. Some say >8. Some say just 1 if within 7 days. Some say 2 if they're within an inch of each other. (seems to me like it all depends on how nice the person you speak to is...) The Apple Support site does not really go into details about pixel abnormalities other than if you suspect you have a high number of pixel abnormalities you may take your machine in for a consult at a store and a consultation fee may apply. (however they define "high number") What would your advice be for a single dead pixel? It's not in a corner somewhere, but it's not dead center either. I notice it the most when I have Word or Excel open and I'm working with that bright white screen and keep reflexively trying to brush it away. It's not enough to really disrupt the functioning of the machine, but it's just annoying enough that it catches the eye when the window/background is a light color. I'm not sure that paying the restocking fee is worth the single dead pixel, especially as a replacement model could be worse. But I am within the 14 days return window, so I could return it and deal with the restocking fee if I had to. So I am wondering - if you get one dead pixel, will that mean you'll eventually get more in a snowball effect? Does having a single dead pixel denote that there's something wrong that could escalate to cause many other dead pixels to pop up, or could one just be an anomaly? I read in one forum that once you get one or two dead pixels popping up, that means that something is wrong with your computer and it will just continue to get worse and worse over time. If that's true, I very well may consider trying to get a replacement iMac... As always, thanks.
