[CGUYS] Mac Monitor problems

Ok, I have a b**ch here. Has anyone else had a problem with burn in on their 24 intel iMacs? I recently took mine in for repair or replacement. They told me it was burn in and wasn't covered by the warrantee. I've owned this computer brand new since 6/09. It is on most of the time. But I

I too understood that LCD monitors can't have burn-in. But exactly what is this 'persistence'? Clearly it's not burn-in, since that's a permanent condition of the phosphors and cannot be fixed short of replacing the crt. I'd like to hear some sort of an explanation of this phenomenon, and perhaps

I dunno, he kind of dances around the question of what actually causes persistence: What this does is cause the LCD crystals to have a memory for their location in order to generate the colors of that graphic. I'm not even sure that's valid English. I _am_ sure it makes no sense to me. What is a

It's good to know this is something called persistence and will go away with time, as compared to permanent burn-in. I've already seen some of the cloudy persistence disappear, however the lines that look like horizontal scratches are back. This is probably due to the fact that I run

I think I might have found a reason, and hopefully a fix for my problem. When I first got this new 24 iMac the display was set to it's brightest, I'm assuming by default. The computer sits on my desk at the same place the last ones have always sat. But the 24 screen set at it's full

The Wikipedia article on LCD Persistence (http://en.wikipedia.org/wiki/Image_persistence) actually has a good explanation, FWIW. Perhaps the reason I haven't seen this on any of our monitors yet is because I have them all set to power down in 2-3 hours. I do not use screensavers. The cause of
