Vivitek DW771USTI – WXGA 3,300 Lumen Interactive Ultra-Short Throw Projector

Product Overview

The Vivitek DW771USTI is a WXGA (1280×800) ultra-short throw interactive projector designed for education and collaborative training environments. Delivering 3,500 ANSI lumens with a 0.35:1 throw ratio, the DW771USTI projects a 100-inch image from approximately 17 inches (44 cm), enabling large-format display in standard-depth classrooms without rear-projection infrastructure. Built-in interactive pen support and Crestron RoomView-certified networking make this projector a practical choice for technology-enabled learning spaces.

Product Description

The DW771USTI uses DLP and BrilliantColor technology with a 10,000:1 contrast ratio to produce clear, detailed imagery under ambient classroom lighting. The ultra-short throw optical path eliminates the shadow obstruction and eye-level glare that limits conventional front-projection setups, keeping the teaching surface fully usable. HDMI 2.0 inputs with 4K signal compatibility allow connection to current-generation computers and media sources without scaling hardware.

For interactive applications, the DW771USTI includes dual-pen interactivity with HID driver-free operation, allowing the pen to function as a computer mouse directly on the projected image. An optional 10-point finger touch unit (DT02/DT03 kit, sold separately) upgrades the system to full multi-touch interactive whiteboard capability. Built-in 20W stereo speakers (2×10W) and a microphone input support classroom audio reinforcement without external amplification. Crestron RoomView, TCP/IP Telnet, and RS-232 support allow integration with enterprise room control systems. Lamp life extends to 12,000 hours in Eco Mode, reducing maintenance overhead in high-use school environments. Vivitek offers a five-year education warranty on this projector when purchased through an authorized dealer by an educational institution.
