Overview
The Epson EB-W51 is a WXGA (1280×800) portable projector using Epson’s 3LCD technology. It is designed for use in classrooms, offices, small meeting rooms or home use where a bright, flexible projection is needed even under ambient light.
Key selling points include:
- A bright output of 4,000 lumens (for both color and white light) ensures the image remains visible in moderately lit rooms.
- WXGA (1280×800) resolution with a 16:10 aspect ratio, which is useful for displaying widescreen computer content and modern presentation slides.
- Compact and relatively lightweight design for a 4,000-lumen projector, making it portable.
- Good lamp life in Eco mode, which helps reduce maintenance and running costs.
- Flexible connectivity (HDMI, VGA, USB etc) and optional wireless support via accessory modules.
