You won't need 3D glasses to read this guide, but you
will if you want to take advantage of today's 3D televisions. The good
news? They ditch the flimsy colored glasses to deliver a 3D image on par
with the best theatrical 3D presentation you've seen, be it "Avatar,"
"Toy Story 3D," or "Cave of Forgotten Dreams." The bad news? Aside from
the need to wear glasses and buy a new TV, 3D TV requires a 3D source
device and 3D content, and even then might not be as enjoyable to you as
watching good old 2D high-def.
To help you,
prospective TV shopper, get a handle on 3D terminology and determine
whether it's something you should care about, we've put together this
handy guide. We think it's a worthwhile read for any TV shopper, even
those who have already decided they don't care about 3D at all.
What is 3D TV and why should I care?:
Whether you consider it a gimmick or breakthrough on par with high-def
itself, 3D TV is here to stay. Here's an overview of the technology and a
few reasons why you should (and shouldn't) give a hoot.
Active vs. Passive 3D TVs:
The main difference is in the glasses. Active glasses use liquid
crystal shutters that run on batteries, while passive glasses use simple
polarizing lenses, similar to what you'll get in most US 3D theaters.
What about 3D content?:
To fully enjoy your 3D TV, you'll need actual 3D content to watch on
it. We break down what's available today (hint: not much), from Blu-ray
to cable/satellite to streaming video to 3D games.
3D TV recommendations:
If you're shopping for a new TV, you may think the decision on whether
to get 3D or not is cut-and-dry. Unfortunately, it's not. Here's our
best advice on how to think about the 3D feature as navigate the market.
