Special display is needed for presentation of 3D-video.
Most often used are:
Dual DLP projector with polarizer filters:
Picture for left and right eye is projected by two separate DLP projectors through polarizer filters onto a silver screen.
Observer must use special polarized glasses separating picture for left and right eye. This is very similar to the principle used in IMAX theatre.
Setup of those two projectors is complicated, requires precise picture alignment from both projectors and mainly expensive silver screen which doesn't corrupt polarization.
Single 3D DLP projector
Special 3D-DLP projector operating on at least 100 Hz frame rate frequency is needed. This projector alternates picture of left and right eye - so called page-flipping method.
Observer must use special LCD shutter-glasses which are synchronized with projector and which pass only information for left or right eye alternatively (synchronized mostly using nVidia 3D Vision or DLP Link).
3D projectors operating on 100 Hz: BenQ, Acer, ...
3D LCD monitor
LCD monitor operating on at least 100 Hz frame rate frequency together with shutter-glasses (synchronized mostly using nVidia 3D Vision).
LCD monitors operating on 100 Hz: Samsung, ...
CRT display
Older CRT display operating on at least 100 Hz frame rate frequency together with shutter-glasses.
Obsolete technology but cheap and easy working, unfortunatelly smaller size of the displaying area limited by diameter of CRT's.
In addition to this special display device, 3D-video playback requires also PC with graphic card and stereoscopic driver and special SW that will support 3D playback. Currently supported only by nVidia graphics cards.
