    When do dead pixels show themselves? If I have a new PowerBook and it has no dead pixels, is there a possibility it will in the future?

    They usually occur at manufacture. Unless you physically kill a pixel (bump the screen or something), it's unlikely that a pixel will die on you. On the other hand, it can sometimes take a little while before a dead pixel is found, even if it has been dead all along. :)

    Usually the day after the warranty runs out :D

    Nah, the above poster is probably right.

    Yep madjew is right.

    All monitors I've had with dead pixels had them from new. All the ones without are still without after a couple of years. :)

    Hi lamina,

    sorry to say, but obviously dead pixels can occur later on as well.

    I have purchased a MacBook Pro 15" about 1 month ago and it was fine up to now.

    Yesterday, I recognized a white dead pixel in the lower third of the display which hasn´t been there the day before. Since my MBP is hardly moved around but most of the time standing on my desk, it seems unlikely that the dead pixel was caused by external bumping or something.

    Also I have heard from other users who said that dead pixels have suddenly appeared on Powerbooks and the likes.

    cheers
    Tom

    Pixels can also get 'stuck' as well as dying. If a pixel appears to be dead that didn't used to be, gently massaging the area around the problematic pixel is said to help sometimes (read this link). I personally have two dead pixels on my monitor (which were there from day one), but neither are very noticeable thankfully.

    Dead or stuck pixels will almost always appear within the first week of ownership. A huge and overwhelming majority of them occur in the manufacturing stage, and it's usually the case that you just didn't notice right away. You can think of it like a house that settles, except on a much faster timeframe--the first few days are basically the display's "shakedown."

    After that, it is extremely rare for a pixel to malfunction unless the computer is subjected to temperature extremes, rough handling, or an impact of some kind.

    I have a dead pixel in the upper left corner of my peecee laptop. I don't think it's dead, but it's always white. I think I dropped it once from about 3 feet onto a wooden floor, but I don't think that's the problem. Perhaps been there all the time? Dunno.:rolleyes:

    Haha my iPod has more dead pixels than I have hair on my head. They're in huge clumps, but it's because I've dropped it so many times
