I have a 120 hz set the ln52b630. I also have a ps3, would I be able to watch 3d movies? or would I have to buy a different tv? I know that they are coming out with 3d t.v s in the upcoming months, but what About people that have a 120hz lcd and a ps3? shouldn't we able to see 3d technology once we get the software update for the ps3?
