Introduction

Projector features

The projector integrates high-performance optical engine projection and a user-friendly design to deliver high reliability and ease of use.

The projector offers the following features:

High quality manual zoom lens

Full-function remote control

One-key auto-adjustment to display the best picture quality

Digital keystone correction to correct distorted images

Adjustable color balance control for data/video display

Ultra-high brightness projection lamp

Ability to display 16.7 million colors

Multi-language On-Screen Display (OSD) menus

8 sets of preset application mode

Switchable normal and Economic modes to reduce the power consumption

Built-in speakers provide stereo audio reproduction

Component HDTV compatibility (YPbPr)

Two PC input terminals (RGB signal input socket and a shared DVI-A connector) and one PC output terminal

Replaceable dust filter

The apparent brightness of the projected image will vary depending on the ambient

lighting conditions, selected input source contrast/brightness settings, and is directly proportional to projection distance.

The lamp brightness will decline over time and may vary within the lamp manufacturers specifications. This is normal and expected behavior.
