Panasonic debuts 3-chip SCGA+ DLP projector

The PT-D7700U offers a 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, the industry’s lightest-weight large-venue 3-chip DLP projector. The heavy-duty PT-D7700U offers a 4000:1 contrast ratio and a 1400x1050 SXGA+ resolution in a native 4:3 aspect ratio, enabling it to work with existing installed screens, while its flexibility is ideal for rental and premium home theatre applications. The PT-D7700U is equipped with a three-chip DLP light valve to produce 7000 lumens of brightness and vivid, true-to-life images. Its dust-proof, sealed, fluid-cooled optical system offers reliability for demanding applications like 24/7 command and control centers.

The projector combines theater-quality 4000:1 contrast ratio with a newly-developed Dynamic Iris, a Panasonic 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 rich, detailed blacks and to masterfully reproduce 24 frames-per-second, film-based video.

The PT-D7700U incorporates Panasonic's BriteOptic dual-lamp system that delivers the power and reliability of two high-intensity 300W UHM lamps through a high-precision prism. Its lamp auto-changer alternates lamp operation to permit extended 24/7 use and allows operation to continue without interruption even if one lamp burns out.
