DLP (Digital Light Processing) projectors are ideally suited to video applications thanks to their high contrast ratio.

There are two types of DLP projector: MONO-DLP (the more common) and TRI-DLP.
The former uses a monochrome panel on which a rotating filter (including the three primary colours, red, green and blue) turns at very high speed, while the latter is equipped with three separate panels, one red, one green and the third blue.

MONO-DLP projectors give perfect black and white pictures while computer projected colours are bland, without depth and far removed from the original. Surprisingly, the colours are vivid and well contrasted in video projection.

TRI-DLP projectors give a perfect picture whether computer or video imaging is being used. However they are mainly intended for the professional market due to their high cost (15,000 to 100,000 euros) and the necessity for impeccable HDTV picture quality in cinema or digital projection.
