30" Display Flickering/Dancing Pixels
I picked up a 30" display and the issues started ... This is not a dead/stuck pixels issue.
Bought the display at my local Apple store, got it home set it up and did the usual dead pixel search, OK there's three of them (two red one green), round the edges and to honest the pixel size on this display is so small that unless you have a cluster of them in one spot then the odd one here or there isn't really noticeable.
But then, after the screen has been on for a while I see green flickering or dancing pixels on the display. They disappear if you move the mouse pointer over them but reappear when the pointer is moved away, in fact this can even make them multiply.
I search here on the forums and found this :
Again 30" display with lots of green pixels
That post also contains a link to another post of the issue (and even includes an image of the issue at :
Flickering green and blue pixel problem
OK, I'm not going mad and it's not my eyes.
So, I return to the store and we can reproduce it on their G5 with GeForce 6800 Ultra. Something I am very pleased about as it proves it's not my G5 of GeForce card, and the store replaces the screen.
Screen #2: Get it home set it up again do the dead/stuck pixel search, none this time, wow OK let's leave the screen on for a while with nothing happening and ... green flicker returns.
Now, it does go away if you turn the screen off then on again. But they do come back. Sometimes not straight away, but only takes a few minutes. So screen #2 will be going back ...
It definitely would seem to be a display issue as in the threads above it happens on ATI and GeForce cards, Laptops and Desktops (though I didn't see anyone having issues on Windows).

[EDIT - Update:
I took the second display back to the Apple Store and we proved it on a third G5 and GeForce 6800 Ultra. Let me make sure that's clear. We demonstrated this to the Genius on hand with two different displays that had the issue on my G5 Dual 2.5 with GeForce 6800 at home and with two G5 2.5's with 6800 's at the store.
The staff were great, they waited until it returned (about 30 minutes) and were very interested when it happened. I made the decision not to try a 3rd screen and took a refund which the store did not give me any hassle in doing so.
I just want to say, if this mail seems to be anti-Apple it is not meant to be. The 30" screen is a great screen, the color was great and it if it were not for this one issue I would be proud to own one. The staff at the store were all polite and helpful.
Hopefully, Apple will realise this issue and find a solution for it.
