My nephew was in my house last week doing a bit of plumbing work for me and he and I got talking about televisions.
He was saying that his mate has a TV that is phenomenal. He could not explain too well. But said that when his friend put a DVD into the TV eg "Toy Shop" the characters nearly came out of the TV. I have asked him to get the name of this TV but he keeps on forgetting.
I would doubt he has a 3D tv as they are still very new and hugely expensive, so he probably has a standard LED tv (which are basically LCD screens but use LEDs for the backlights instead of tubes)
i sorta googled 3d televisions there - and whilst did not read thoroughly - it seems in order to get a better advantage - do you need to wear glasses to get the full effect. (I would not want that)
