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
