Product Overview

The Vivitek DX813 is an XGA (1024768) short-throw DLP projector delivering 3,600 ANSI lumens with a 0.521:1 throw ratio. Designed for education and corporate AV environments, the DX813 combines short-throw projection with LAN control, comprehensive connectivity, and a filter-free sealed optical engine in a compact white chassis. Full HD 3D support via DLP Link and a lamp rated for intensive daily use make it a practical choice for fixed classroom and training room deployments.

Product Description

The DX813 uses DLP and BrilliantColor technology rated for intensive use 12 hours per day without image yellowing or color degradation over time. Its 0.521:1 throw ratio reduces the distance between projector and screen, minimizing shadow interference compared to standard throw units in space-limited rooms. The sealed optical engine eliminates filter maintenance requirements throughout the projector’s service life.

Connectivity covers HDMI 1.4, dual VGA inputs with VGA output for monitor feed-through, S-Video, composite video, and a USB-A port (power only). An RJ-45 LAN port provides network monitoring and management capability compatible with Crestron RoomView and other AV control platforms. A microphone input and built-in audio output support basic classroom audio coverage. The DX813 ships in white and is appropriate for ceiling-mount installations requiring a low-profile white finish.

Frequently Asked Questions

What is the minimum throw distance for the DX813 on a 100-inch screen?At a 0.521:1 throw ratio, a 100-inch diagonal (approximately 2.03 m wide) requires roughly 1.06 m throw distance.Is the DX813 compatible with widescreen sources?Yes. The DX813 accepts 16:9 signals and scales them for display, though its native 4:3 XGA resolution is optimized for 4:3 content from legacy computers and document cameras.Does the DX813 require filter maintenance?No. The sealed DLP optical engine is filter-free, eliminating periodic filter cleaning or replacement throughout the projector’s service life.
