After a faithful 7 years of service from my Panasonic PT-47WX49 HD RPTV, I'm finally ready to retire the old gal and upgrade to a new set. Having recently moved into a new house with a finished basement perfectly suited for a home theater, I've turned my eye on the new Panasonic 58" V10 plasma. I was paranoid about RPTV burn-in when I pulled the trigger 7 years ago, but I calibrated with Avia and never had any problems. I played plenty of video games and watched a ton of 4:3 content as well as plenty of sports with static overlays. I'm sure this is just a result of having contrast set to its proper levels (if not a little lower) and the only real reason I'm upgrading is the lack of HDMI/1080p/720p support. The set still looks great. As you can imagine, now that I'm considering a move to plasma, my paranoia has returned. I know that great strides have been made in Plasma technology in the last few years, but I see some people still claiming that burn-in is still real and common and that you have to be a "responsible watcher". Is that really the case? With proper calibration and not doing anything stupid (like leaving it on and paused overnight) how susceptible to burn-in am I going to be? I never want to be in the situation where I have to say "I would love to watch this movie marathon, but it's 8 hours of 2:35:1 and I shouldn't risk it". After all, tv is for enjoyment and if I have to make decisions like that, it detracts from that enjoyment. If its really a problem, then I supposed I'd go LED, but everything I read still says plasma is quality king. 1. Light controlled environment 2. 33/33/33 Movies, Gaming, TV 3. Picture quality is my most important feature in a TV Thoughts?
