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-
