Introduction
General Descriptions

Product Overview
The Projector consists of the DLP projector controller, Lamp controller, Power supply system,
and the system cooling controller. The DLP controller captures the digital PC data and video
data and converts them into the DMD display device. The lamp controller controls the lamp’s
power and synchronizes its frequency with color display sequence. Power supply unit
controls the AC line power factor and converts primary voltage to secondary low voltage for
digital board. The system cooling controller drives the airflow to cool the lamp’s heat and
electrical component’s heat.

(1) If pattern can be uniformly focused (not worse than Limit
Sample), then pass!
(2) If it’s difficult to judge, then check 2.6.2

2.9 Dynamic Contrast Ratio
(DCR)
1. When RGB value of content input is smaller
than 20%, system will automatically switch to Eco mode, if
RGB value is greater than 60%, the projector will back to
Normal mode.
2. When DCR function turns on, lamp mode function is
grayed out to disable; when DCR function turns off, lamp
mode would return to setting value.
(Viewsonic agreed to take reliability and noise impact
caused by DCR function, but detailed specification of DCR
above would be finalized to suitable for reducing reliability
and noise impact by Qisda after PVT sample)
