3D Projectors

3d-red-cyan-glassesApart from using red blue type glasses not all projectors will work with superior shutter glasses (similar to the battery powered active glasses used with many modern tv's). Resident expert Paul Gibbs shares some advice on how to find out if your projector will be suitable for 3D movies or gaming.

For large audiences like clubs or pubs polarization modulators similar to those used in front of many cinema projectors are available to use with cheaper Passive glasses.

There are probably more DLP 3d capable projectors than other types probably because of the high speed response time of the Digital  Light Processing mirror devices used to display the images.

Older DLP projectors are less likely to work in 3d but do not despair as many can be used at lower frame rates with computers running at 60 85 or even 100 frames per second, obviously with minor flicker issues at the lower frame rates.

Only more recent projectors with HDMI inputs can play 3d Blu-ray Discs and some that do have HDMI inputs are only "3d ready " and require an additional converter between the Blu ray and the projector. However "3d ready" projectors should work with compatible 3d games from a computer in Frame Sequential 3d, that is for example left full picture followed by right full picture running at half the frame rate per eye  TV is usually 120hz  = 60hz per eye

There is a 3d compatible projector list at http://www.3dmovielist.com/projectors.html and also www.3dmovielist.com/projectors.html

A final note on 3D compatibility and 3D formats: Most of the 3D projectors listed here ONLY support the frame-sequential 3D video input mode.
