The Christie E Series 675/775 projectors deliver up to 6,700/7,200 ANSI lumens and 5,000:1 contrast ratio;
ideal for small auditoriums, and medium-to-large meeting, training, and conference rooms. The Christie

and DW775-E provide WUXGA (1920 x 1200) resolution for maximizing image detail.
All four models have dual mercury lamps and each has the unique capability to optimize its lamp configuration
for maximum single lamp operation. These models also utilizes a high brightness six-segment color wheel
(RGBCYW) with an optional “best color” color wheel (RCGCYM) available when color precision is crucial.
The color wheel ensures radiant colors while eliminating artifacts from fast moving content, leaving audiences
with only razor-sharp images.
