IMac Screen Burn

I have a 24in IMac bought last Sept. I am getting instances of screen burn usually my web browser. When I have it up for along time it seems to burn (slightly) that page.

I have the computer set to sleep after an hour of no activity I had stopped using a screen saver but recently went back to it. (set to go on after 15 minutes)

Anyone have these issues? The burn seems to go away after a while (haven't really timed how long it takes to dissipate)

I would hope that the SS should help with this issue... never had any problems with my samsung monitors prior when using windows on my pc...

It isn't burn in per se - but LCD persistance.

I am having the same trouble with an older Dell monitor. I setup a screensaver that displays all white for 5 minutes - all black for 5 minutes - it seems to be helping my monitor out.

thanks for the link, you learn something new everyday
