Optoma Introduces Its Latest Home Theater Projector Featuring the DarkChip 3 DLP Chipset

MILPITAS, CA (July 8, 2005) — Optoma Technology, Inc. announces the availability of the H78DC3, its newest high performance digital projector for home theater enthusiasts. The H78DC3 features Texas Instruments’ DarkChip3 DLP chipset that delivers vivid digital images, as well as a 5X speed, 8-segment Dark Video Enhancement (DVE) color wheel and a 4000:1 contrast ratio to deliver subtle color details.

The H78DC3 home theater projector uses DarkChip3 DLP technology to assist in projecting higher brightness and deeper black levels; the H78DC3 is able to do this because the mirrors are placed closer together than in previous DMD chips. Offering remarkable display capabilities, the H78DC3 is a native 16:9 HDTV projector that features vertical lens shift control to adjust the vertical position of the projected picture.

With a 5x speed and proprietary 8-segment DVE color wheel, the Optoma H78DC3 can produce superior dark scenes. The improved processing of color allows the projector to deliver vibrant bright scenes and further enhance darks for extraordinary video performance.
