I have had this tv for 6 months now, and although the 2d picture for blu-rays is amazing, the 3d is a let down, if you really want to focus on 3d, please look to another tv like the sony led 903 it has way way way better 3d... alhough it's also twice as expensive, but you get what you pay for i guess.
The 3d on this machine adds a little depth, but nothing really comes out of the screen as you would expect with a 3d tv. Also dependant on the glasses provided the ones ending 100 are really bad for both xtalk and syncing constantly with the tv, causing you to see flashes... It really does spoil the viewing.
For 2d purposes, if you're an lg fan get the few years ago model 350 i think, people rave about it and it's a third of the price.
I you do get this forget it for ps3 gaming, or xbox, as popular games have static symbols, i have had a level bar image retention at the bottom of my screen for over a month now. And when you get carried away in a game the last thing you're thinking about is image retention, and color/white washing you're tv. Plasma's really are high maintenance. SO BE CAREFUL
Fortunately my tv has little to no line bleed, however Check av forum online for comments of people who have this tv (including myself), most of them are returning it and getting another brand of tv due to the many many flaws.
