ABOUT LASER DLP (Digital Light Processing) PROJECTION:
Much information can be found online regarding the advantages of laser DLP projectors over previous technologies which utilize metal-halide lamps. While some may reference “a downside” or “con” of this newer technology as having “greater, initial expense” this is by and large no longer the case, as laser DLP is well on the way to becoming the dominant technology (in particular, for medium and large venue video projectors).
For several years, the consistent message within the industry is that laser DLP projectors are superior in virtually every way, including image quality, over-all reliability, efficiency, maintenance- free operation, and most profoundly, in their ability to maintain their brightness over time. This last noted improvement is key when considering the use of projection for any permanent installation.
The vast improvement of performance is illustrated in the following comparion chart from AVS forum, which compares a typical lamp- based projector with 50% of it’s initial brightness after 500 hours of use, to a laser- based projector with 80% of initial brightness at 30,000 hours of use.

ABOUT ULTRA- SHORT- THROW PROJECTION:
Another development in digital projection that has come almost in tandem with the arrival of laser DLP, are advanced optical systems that allow large images of great quality to be projected with very little throw- distance. In the following example, the projector is less than 30 inches from the projection surface, and the projected image is just over 10 feet wide. For anyone with experience in digital projection, this is immediately observed as a game- changer. While not suitable in every instance that projection might be considered, this unique technology opens possibilities for the application of video projection that were not possible before.
