Panasonic delivers HD high contrast DLP projector


Panasonic’s PT-D7700U DLP projector offers 4000:1 contrast ratio and a 1400x1050 SXGA+ resolution in a native 4:3 aspect ratio.

Panasonic Broadcast is now delivering the high-resolution PT-D7700U large-venue three-chip DLP projector.

The heavy-duty projector offers 4000:1 contrast ratio and a 1400x1050 XGA+ resolution in a native 4:3 aspect ratio. The projector is equipped with a three-chip DLP light valve to produce 7000 lumens of brightness and vivid images.

The projector combines theater-quality 4000:1 contrast ratio with a newly-developed Dynamic Iris, a Panasonic exclusive technology that constantly monitors the amount of light output and adjusts the intensity of the light source to match it. Dynamic Iris integrates with Dynamic Gamma correction to increase highlights so that as blacks get blacker, the bright areas remain bright. Its Dynamic Sharpness control increases image sharpness without adding noise.

The unit’s high-speed digital signal processing (with 16-bit color depth for wider dynamic range) and progressive cinema scan (3/2 pull down) capabilities team to produce detailed blacks and to reproduce 24fps film-based video.
