Power Supply (V)

A:AnswerNope, system of this tv is locked, or like ios. You only can download the apps from inside store (just a few). But I think it's ok~ I am a player~
A:AnswerI am guessing no. To be 3D compatible it would have to have at least a 120 rate and preferably 240. The "120" on this is a fake "burst duplicate" speed and not true 120. I wouldn't count on it for being able to handle 3D video... at all.
