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 brightness is just to much in your face bright. So
when I first got this I turned the brightness all the way down. For
some reason a few weeks back I had turned it all the way up again. And
that's when my problems started. So now that I've dimmed this thing
down again I'll give it a few days or a week and see if this
persistence goes away.

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 see an example. Does it also happen with LED LCDs?
Take a look at this discussion of LCD persistence.
