March 24, 2010 - 3D was the big push at this year's CES, and now the products unveiled at the show are making their way into stores. But with all the terms and technologies at work, it's pretty easy to get turned around. Follow our guide to 3D to find out what you need, why you need it, and what it all does.

What you need:
3D technology doesn't really contain any particular piece of technology that you haven't seen before. The TVs aren't all that different from regular 2D sets, as are the Blu-ray players, cables, ports, and glasses. What is different is that 3D synchronizes all of these parts to produce a highly coordinated image with the illusion of depth. So the basics of a 3D set up are: a newfangled 3D HDTV, active-shutter LCD glasses from your TV's manufacturer, and a Blu-ray player, 3D-capable console, or cable box with HDMI 1.4 ports.
