3D Projectors are one natural trajectory for the projector technology in the near future. "3D Ready" means that the projector, with the right 3D conent, and accessories, can produce two virtually simultaneous images essential for the 3D image viewing model. Then, thanks to active or passive glasses, deliver those two image streams, one to each of your eyes.

As of the end of 2010, the amount of 3D content remained rather limited. Other than the gaming world, where PC gamers can convert many 2D games to 3D games, on the fly, with the right graphics cards, such as some Nvidia display card models, it's downright sparse.

Few movies exist in 3D, though those are well known. in late 2010, there were few 3D movies, and most under temporary license only to one manufacturer, not much to buy. Not so, a year later, as my 3D movie collection is now in the dozens, and there's lots more 3D contetn - 3D movie, 3D sports, and lots of Discovery HD type content in 3D, to be found on cable and satellite
3D Projectors that use single chip technology, such as those single chip DLP projectors that are 3D Ready, work with those expensive active LCD shutter glasses. Today almost all 3D projectors for your home, schools and business are using active shutter glasses.
