First of all there is a noticeable buzzing noise coming out of the back, probably normal but it's quite loud. Also, when I connect my PC to it via HDMI, the resolution blurs and then refocuses every 60 seconds - but not when I'm playing my Xbox. Maybe it's my PC. I don't know if I want to risk getting a replacement sent out if it's going to do the same thing.
Please keep in mind that I am a major gamer and response time is very important to me. The Panasonic I am returning had the best response time I've ever played on for a screen that size. I'm kinda bummed I have to return it.
Also, I hate that Soap Opera Effect that some TV's have when watching movies - if any of these will do that, let me know please!!
