very bright projectors on a small screen. Avoid using stronger projectors than

necessary for your screen size and ambient lighting conditions.

The contrast ratio has greatly improved over time. Modern DLP projectors,

utilizing second generation “black chip” Texas Instruments DLP technology,

often provide a contrast ratio of 3000:1 or better.

Keep in mind that when using WATCHOUT with projectors, you get the

combined brightness from multiple projectors. Hence, good contrast and color

saturation is often more important than high brightness. Hence, choosing a

“home cinema” projector may be better than an “office grade” projector due

to the better color fidelity and often lower noise level of the former.

To determine the suitability of a particular model of projector, always perform

proper tests under realistic screen size and lighting conditions. Details vary

widely among manufacturers and projector models, and are not always stated

on specification sheets.

A good starting point when looking for a projector may be one of the many

dedicated web sites, such as: http://www.projectorcentral.com/.
