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)
