2 years ago I wondered if it would be a good result to play on the whole screen instead of half of it by using a 3D TV and a pair of glasses where the polarization was equal on both eyes but different from the opponent. At that time I didn't have a 3D TV, but now I have the TV and have of course tested it.

With a passive TV it works easily by doing as in this movie clip but if active glasses are modified electrically it would also work for an active 3D TV. In theory an active 3D TV would be capable of giving full screen viewing to more than two different persons if doing as follows:
1. The 1:st frame to person 1, everybody else have black glasses
2. The 2:nd frame to person 2, everybody else have black glasses
3. The 3:rd frame to person 3, everybody else have black glasses
4. The 4:th frame to person 1, everybody else have black glasses
5. Continue in the same way

But for every extra person the TV need to increase the total framerate in order to maintain the framerate for a specific person.
