    Alright, here's the situation. On my ACD 23" Display - whenever I run a program (any program it seems) I get a blue pixel that appears about 50 pixels on top of the dock in the center. It looks like a stuck pixel, but wouldn't it stay there after I quit out of programs? It doesnt come up in screenshots so I doubt it is a program thing.

    But here's the twist -- If I play a DVD or even open up Virtual PC running Windows in fullscreen mode - the pixel is gone.

    It is quite a strange occurance and I wish I hadn't noticed it, because now my eye is always going down there and I absolutely hate display anomolies, no matter how insignificant or small. I tried doing the massaging the screen or even running pixelmurder quicktime file. None of which solved the issue.

    My question is... does anyone ever see something similar? The machine I am running is a G5 dual 2.0ghz / 3gb ram with Tiger 10.4.8 -- if that makes a difference or not. Tonight I am gonna hook it up to my powerbook g4 and see if I get the same issue.

    Any ideas?


    OH... and if anyone wants to buy my powerbook, less than 5 hours left on the auction: http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=150050551185

    Going to macbook c2d pro soon!

    I had a problem with pixels one time. Every so often a load of red pixels would randomly flash all over the place. I eventually got rid of the monitor only to find it was the graphics card :rolleyes: Cost me a freakin fortune!

    Maybe there is a GPU problem?

    Possibly try reseating the card.

    Yep, that's the graphics card that is overheating. It was probably very dusty and in need of cleaning?!?

    The OP seems to have a dead subpixel. That would explain a coloured dot on a white background and no dot on a black background. It could possibly be two of the three colours dead on the pixel. I've got a similar situation - Eizo lived up to their reputation and shipped me a pixel perfect panel, but TFTs are TFTs, and this one developed before my eyes after a few hours of use (literally, I saw it flickering) Unless it really bugs you, and since it is close to the bottom of the screen, I wouldn't try and get it replaced. It'll only be a huge headache and Apple give no promises at all that a replacement will be perfect.
