Does this sxrd have the "burn in" effect. Some guy told me at best buy that the reason why most plasma tv's dont have pc inputs is because something about a "burn in effect" i think he said. he said after using your pc to tv and you have a still image, you will have to keep the tv on about 30 minutes to get rid of that stil image. And he said lcd's do not have this problem. Is this sxrd going to have this problem?
