Cinema Display - Dead Pixel Test

[Adokimus]

Hi again, I was wondering if anyone has any advice on how to quickly test an Apple Cinema Display. I found a good deal on a used one, but I want to check it out before I buy it. I have never had a dead pixel on any display, so I don't know what they look like. Does anyone have a high-res picture of an example? Also, are there any other issues that I should be on the lookout for? I know the MBP with the LED has yellowing issues... are there any equivalent issues to keep my eyes peeled for with an ACD?

Thanks so much,

Ado

A dead pixel is black, regardless of the colours of the surrounding pixels.

they just look like a pixel that is grey, or if they are stuck just random colors. when you check it out just look at it and if you can't see any then you probably do not have any or at least none that will bother you.
