As you are fond of 3D movies, I would suggest you go for passive 3D glasses because they are much more comfortable and very light in weight. Active glasses can cause discomfort for some and I personally can't watch a whole 2 hour movie without taking several breaks in between. I recommend LG and Panasonic for passive sets.
I am planning to buy Samsung UA46D6600 smart TV + wifi, but I need to know few things before I buy.
I have 3D movies (side by side) can I play these movies on it?
What benefits I can get from wifi?
