Hi, I have a 57HDX82 RPTV and most of the time i use to watch DVD's or to play videogames. But i was worry about the burn-in since the one of the game we play a lot is Tekken and i and you know this game has the big green life meters on top of the screen. Usually we play 2 hours non-stop. So do you think this will cause burn-in? Oh and is burn-in cumulative?I mean does the TV act as if it forgot what happened during those videogame sessions when i turn off the TV?
