Can the 3D feature on a 3D TV be tuned off?
yes. All 3D TVs will display current 2D content with no problem and no glasses required, and we don’t expect their picture quality in 2D to be any worse than on an equivalent 2D HDTV. the Blu-ray 3D specification calls for all such discs to also include a 2D version of the movie, allowing current 2D players to play them with no problem.
