2D on 3D TVs

Talking to a colleague yesterday he mentioned that someone had told him that you'd need to wear the glasses with a 3DTV all the time, even if you're watching a 2D channel, that's not correct surely?

Indeed not. Normal SD and HD viewing won't require 3D glasses.

I don't think that will be the case. Stereoscopy involves capturing stereo pairs in a two-view setup, with cameras mounted side by side, separated by the same distance as between a person's pupils. The 3D TV tells the glasses which eye should see the image being exhibited at the moment. If you switch off the 3D mode, or watch a 2D programme, you won't need this information from the TV to the glasses.

If you want to watch a 3D content in 2D, you can simply turn off the 3D option. The TV will just show the view for only one eye. If the refresh rate of the program is high enough, you should not notice much of a difference in picture quality.
