I have read the forums about burn in on the iMac. I want to download some games but that may ate up to 5 hours. How do I do this without getting burn in or image retention?
I agree it is much better than a screensaver, there were plenty of people here with iMacs asking that question and the answer was always you can't, this tip is a good tip if it works on all iMacs, thanks for this.
(I don't have an iMac myself but good to know)
