I'm in the market for about a 2,000 rptv. I am completely new to this. I will use if for dvds/tv/video games. Do video games cause problem?? I am looking at either a 47/48 inch or 50 inches. I sit about 8-9ft away. I am worried about burn in but I read that as long as contrast is set correctly etc that I should be fine? Does that hold true for video games. Are some sets more likely to burn in that others in my price range? Any suggestions on what I should research will be greatly appreciated.
