Going back to 3-D on television before I forget. Makes a huge difference if it is active 3D or passive 3D.
If your 3D glasses require batteries, then its active, and the 3D effect is done by flickering the lenses back and forth at high speed. With active 3D, there are reports of headaches, visual overload, and can cause epilepsy problems with some people. With passive 3D, like my Vizio uses, the glasses do not use batteries, and look more like sun glasses. One side of the lens sees the vertical signal transmitted, and the other side sees the horizontal signal, so when you wear them, the combined effect gives you the 3D effect. Haven't heard of any "health" issues for those using passive 3D. Something to think about
if you are choosing a 3D television set. Active glasses can easily cost 50-150 a pair, where the passive glasses can be had for as little as 7 bucks a piece.
With both tv 3D technologies, you need a blue-ray player with 3-D capabilities to watch movies on DVD. But not to watch aired or broadcast 3D movies, and it pays to have super fast Wi-Fi capability, because you are down streaming two signals simultaneously. With most 3D TV's, the tv needs to see the signal in Side-by-Side mode, again, one vertical signal and one horizontal at the same time.
