Well first off, 6.5ms is horrible for gaming. I have had at least ten tv's over the last few years. I have had LG 120hz 47 inch lcd, Samsung 55 inch led lcd 120hz 3d, hp 37 inch, proscan 32 ( for my daughter), Toshiba 240hz 47 inch, phillips 47 120hz inch lcd, etc.. Also have a 51" inch Samsung Plasma 3D 600hz. The Phillips had a 2ms response time and blew every TV I had out the water as far as smooth motion and gaming. Second I would put the LG, third the Toshiba, which both had around a 5ms response time. Now the plasma...it craps all over all those TV's for fast motion and gaming. LCD and LED's ( which are still LCD just LED lit) pass a light through a liquid crystal which twists accordingly to display a pixel in a picture. This takes at least 2ms. A plasma sends electricity through a gas an instantly displays a color pixel. Plasma's have response time of .0001ms. this totally illiminates motion blur. Couple that with a 600hz refresh rate and plasmas are super smooth for fast moving movies and gaming. Also all these TV's that say 240 hz or 480hz that are led are not true. A 240 hz is really a 120 hz with backlight scanning, and a 480 hz is really a 240hz with backlight scanning. This creates the illusion of 480hz but is a minupulated # and not a true 480hz. LED's that are true 240hz can only display about 800 lines of resolution for 3d. A plasma has the speed to display a full 1080 lines of 3d resolution. Plasmas also have deeper blacks and better colors depth as well as a deeper depth perception which makes movies, games and especially 3d images seem more 3d. LED's do have an advantage in brightness, but its not much. LED's use a little less power, but your talking a couple dollars per year!! Now the BURN IN: This was a problem like 10 years ago when they first came out. Now it is almost impossible to burn in a screen, especially if you buy a good brand. Is it possible? Yes, but it is possible to burn in an LCD or LED or CRT. New Plasma's use pixel shifting and a better phosphorus gas to prevent these things. There is more of a risk with the cheaper manufacturers of Plasma's. Google Samsung wins C-net's accidental burn in test, or HD Guru fails to burn in plasma. So bottom line a Plasma will out perform and LCD or LED any day place or time. Once LED's have true refresh rates over 800hz they will complete with Plasma's, but this will be very hard since no matter what it is still Liquid crystals which take time to shift!!
