Vivitek DW770UST – WXGA 3,500 Lumen Ultra-Short Throw DLP Projector

Product Overview

The Vivitek DW770UST is a WXGA (1280×800) ultra-short throw DLP projector delivering 3,500 ANSI lumens with a 0.35:1 throw ratio, projecting a 100-inch image from approximately 44 cm (15.75 inches) from the screen surface. Designed for education and corporate deployments where space constraints prevent standard-throw installation, the DW770UST eliminates shadow obstruction and presenter glare while providing Crestron RoomView network management and a built-in 20W stereo speaker system for classroom audio reinforcement.

Product Description

The DW770UST uses DLP and BrilliantColor technology with a 10,000:1 contrast ratio to produce clear imagery under ambient classroom lighting. Its ultra-short throw optical path, with an embedded reflective mirror and low-profile chassis, allows ceiling or table installation directly adjacent to the projection surface. A sealed optical engine with enhanced ventilation reduces dust sensitivity and eliminates filter maintenance requirements.

HDMI 2.0 inputs with 4K signal support allow connection to current-generation computers and media sources. Crestron RoomView, TCP/IP Telnet, and RS-232 support provide certified AV management system integration. Built-in 20W stereo audio (2×10W) with microphone input handles classroom audio reinforcement without external amplification. A top-loading lamp access cover simplifies on-site lamp replacement, and the lamp is rated for up to 12,000 hours in Dynamic Eco mode, reducing replacement frequency in fixed installations.
