Epson EB‐685WI 3500 Lumens WXGA Ultra Short Throw Projector
Ultra-Short-Throw WXGA Interactive Projection
The Epson EB-685Wi is a WXGA (1280x800) 3LCD ultra-short-throw projector with 3,500 lumens of color and white brightness and a 14,000:1 contrast ratio. It projects up to 100" images from ~11" (0.28–0.37:1 throw ratio), minimizing shadows in classrooms and boardrooms. Dual-pen interactivity enables teacher-student collaboration with annotation capabilities. 3LCD technology ensures vivid colors in daylight. Users praise its interactive features but note WXGA resolution may limit detail for high-definition content.
Advanced Collaboration and Connectivity
The EB-685Wi supports dual-pen annotation, split-screen for dual content display, and multi-PC projection (up to 50 devices) with moderator control via EasyMP software. Optional wireless (IEEE 802.11b/g/n) and iProjection App enable content sharing from Chromebooks, iOS, and Android devices. Connectivity includes 3x HDMI (1x MHL), VGA, USB, and LAN. Users value the wireless sharing and interactivity but report occasional lag in busy networks and the need for an optional wireless module (~$99).
Cost-Effective and Reliable Design
The 250W UHE lamp lasts up to 5,000 hours (Normal) or 10,000 hours (ECO, 2,900 lumens), reducing costs. The 16W speaker suits small to medium rooms, and auto-brightness adjusts to ambient light for energy savings (373W Normal, 0.39W Standby). The 5.8 kg unit includes a wall mount for easy setup. Users appreciate the long lamp life but suggest external audio for larger spaces.
