3D TV: What is dual play?

Imagine playing a first-person shooter with a mate and being able to see only your screen, and having them only able to see their screen.

No peeking, no cheating, and best of all, a full screen to work with. With LG’s recently launched range of TVs, this sort of thing is possible, with the new “dual play” glasses.

Curious how the technology works? We invited a few friends over to show how dual play works, and how closing one eye with a regular pair of 3D glasses can let you see each screen.
