Projects Beautifully in Small Venues
Insufficient space is no longer an issue with EW331U-ST short throw projectors. All you need is 24.8” to project a clear, easy-to-read screen image approximately the size of a 60” screen. When placed on the tabletop edge, the EW331U-ST presentation projectors clear workspace and eliminate issues with the projection light path.

High Functionality and Reliability
The wide angle projectors are packed with operational features, like Crestron® and JPLink® compatibility for plug-and-play operation. Lamp life is an impressive 5,000 hours, which translates to lower maintenance and reduced operating costs. Presenters no longer have to speak over the projector, because these projectors offer silent 28dB operation in low mode. Closed caption as well as 18-language on-screen display capabilities give the short throw projectors added functionality.

Superior Image Quality and Vibrancy
EW331U-ST presentation projectors reproduce vivid images using 3,000lm brightness and a high contrast ratio of 2700:1. BrilliantColor technology with a six-segment color wheel and Texas Instruments DLP® ensure rich, true-to-source color. Color tone adjusts automatically, so images remain high quality even when projected onto color backgrounds. EW331U-ST projector comes with a 3-year parts and labor warranty, 1-year 500 hour lamp warranty and 3 years on the Express Replacement Assistance (ERA) program.

Lamp Compatibility Information:
Mitsubishi DLP® and LCD projectors have been manufactured to strict specifications and are designed for use with genuine Mitsubishi replacement parts for optimal performance. The lamps used in Mitsubishi DLP® and LCD projectors are critical parts. The factory-provided lamps were specifically designed to meet certain performance, quality, and design specifications. Non-Mitsubishi lamps may not meet those same standards, may not be compatible with your projector model, and/or may not be as reliable and durable as Mitsubishi lamps, all of which may negatively impact the performance and operation of your projector.
Replacement of the factory lamp with, or any other use of, non-Mitsubishi lamps, including but not limited to counterfeit lamps, is strongly discouraged and may reduce coverage under our limited warranty and service policy.
