Vivitek DX813 – XGA 3,600 Lumen Short-Throw DLP Projector (White)

Product Overview

The Vivitek DX813 is an XGA (1024×768) 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.
