projector with high brightness and high contrast.
Panasonic's solution: the PT-D7700E series.
Featuring Texas Instruments Digital Light Processing
resolution (1,400 x 1,050), the PT-D7700E series delivers outstand-
ing 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 con-
trast 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-D7700E series also incorporates improvements in reliability
and durability. Allowing extended-time operation, these models let
you enjoy the superior image quality provided by DLP
in a wide range of operating environments.
With superior brightness, image quality, reliability and extended-
time usability, PT-D7700E models meet a host of applications in
auditoriums, conference rooms, control centres and other facilities.
