Short-throw projector Vivitek DW355ST — 3,200 lumens, 1280×800 WXGA

The Vivitek DW355ST short-throw projector delivers 3,200 lumens of brightness with a native 1280×800 (WXGA) resolution, designed to produce large, clear images from a short distance. Suitable for classrooms, meeting rooms and small venues, this compact projector supports presentations and video content in environments with ambient light. Short-throw optics reduce shadows and glare from presenters while enabling flexible placement where space is limited.

Advantages

The projector combines high brightness and WXGA resolution to maintain readable text and detailed images in well-lit rooms. Short-throw projection minimizes distraction from presenter movement and simplifies installation close to the projection surface. Its compact footprint supports mounting or portable use in confined spaces, and common input options accommodate typical laptop and media player connections.

How to use

Place the projector at the recommended short-throw distance from the screen or wall according to the projection size required. Connect a laptop or media source using the available video inputs, adjust keystone and focus to obtain a sharp image, and set brightness and color modes that suit ambient lighting. For fixed installations, secure the projector using an appropriate mount and route cables to the source devices. When used portably, allow a short warm-up time to reach stable image quality.

Usage recommendations

For best readability in classrooms and meeting rooms, position the projector to avoid direct light on the screen and select a presentation mode or higher brightness setting in well-lit environments. Use short-throw placement to keep presenters outside the projection cone and reduce shadowing; perform periodic lens cleaning and ensure adequate ventilation during extended use.
