I have had my 55" HDTV for alittle over a year. Despite warnings included with the TV and Video game I have been gaming on my main system. I have had the brightness and contrast levels at about 33% and try to mix movies, TV and gaming to avoid stationary images that may cause burn-in. I periodically check for burn-in and was fine until recently. I just noticed the faintest burn-in from "health meters" on a particular game. I have to be viewing bright screen with no images and know where to look as well as squint a bit to see the burn. I HIGHLY RECOMMEND NOT gaming on RPTV even if you think you are being careful.
