T o faithfully reproduce vivid images with
both bright and dark areas—the moon in a
night sky, penguins in the snow, patterned
animals on a grassy plain— you need a projector
with high brightness and high contrast. Panasonic's
solution: the PT-D7700U series.
Featuring Texas Instruments Digital Light Processing
resolution (1,400 x 1,050), the PT-D7700U series delivers outstanding
7,000-lumen brightness and 4,000:1 contrast.*
A number of breakthrough Panasonic technologies make this per-
formance possible. Our Dynamic Iris, for example, improves contrast
by precisely matching the lamp output to the input signal. Working
together with our liquid-cooled optical engine, the Dynamic Iris
helps produce images with astonishing definition.
The PT-D7700U series also incorporates improvements in reliability
and durability. Allowing extended-time operation, these models let
you enjoy the superior image quality provided by DLP
a wide range of operating environments.
With superior brightness, image quality, reliability and extended-time
usability, PT-D7700U models meet a host of applications in auditori-
ums, conference rooms, control centers and other facilities.
