Epson EB-685WI Ultra-Short-Throw Interactive WXGA Projector

Epson EB-685WI Ultra-Short-Throw Interactive WXGA Projector

The Epson EB-685WI Ultra-Short-Throw Interactive WXGA Projector turns any classroom or meeting-room wall into a large interactive display without the shadows and glare of a conventional throw projector. Sitting just centimetres from the wall, the Epson EB-685WI Ultra-Short-Throw Interactive WXGA Projector throws a bright 60 to 100-inch WXGA image, so the presenter can stand at the board without blocking the light path. With 3,500 lumens of equally high white and colour light output from Epson’s 3LCD technology, the picture stays vivid even with the room lights on.

Why Choose Epson EB-685WI Ultra-Short-Throw Interactive WXGA Projector?

Classrooms and training rooms choose this model because the ultra-short-throw design removes the two classic projector problems: shadows on the screen and light shining in the presenter’s eyes. The Epson EB-685WI Ultra-Short-Throw Interactive WXGA Projector adds dual-pen interactivity, so teachers and trainers can annotate directly on the projected image, save notes and drive the connected computer from the board. A 16 W speaker covers a typical classroom without extra audio, and the included wall mount and pen tray keep installation tidy.

Key Features

• Ultra-short-throw 0.28:1 lens: projects 60 to 100 inches from just centimetres away from the wall, eliminating presenter shadows
• Dual-pen interactivity: two interactive pens included, so two users can write and annotate on the projected image at once
• 3,500 lumens 3LCD brightness: equally high white and colour light output keeps colours vivid in normally lit rooms
• WXGA 1280 x 800 resolution: 16:10 widescreen image that suits laptop and tablet content without cropping
• Flexible connectivity: three HDMI inputs plus VGA, USB and network control for classroom and meeting-room sources

Best Suited For

The Epson EB-685WI Ultra-Short-Throw Interactive WXGA Projector is best suited for classrooms, training rooms, coaching centres and corporate meeting rooms where the presenter works at the board. It is a strong fit for interactive lessons, annotated presentations and collaborative workshops, and for rooms where a long-throw projector would cast shadows or need a ceiling mount far from the screen.

Setup and Connection Guide

Mount the projector on the included wall mount above the board, following the installation guide’s throw-distance table for your target screen size, then connect the computer over HDMI and the interactive pens’ USB link. Calibrate the pens once using the on-screen calibration routine, adjust the image with the manual focus and digital keystone controls, and connect the 16 W speaker output or a room audio system if a larger space needs more volume. For network management, connect the LAN port so IT staff can monitor and control the unit remotely.

Frequently Asked Questions

Does the EB-685Wi support finger touch?

No. The EB-685Wi supports dual-pen interactivity only. Finger-touch control is the step-up EB-695Wi model, which adds a touch unit to the same ultra-short-throw platform.

What screen size does it produce?

The Epson EB-685WI Ultra-Short-Throw Interactive WXGA Projector produces a 60 to 100-inch image at 16:10 from its ultra-short-throw lens, mounted just above the display wall.

How long does the lamp last?

The 250 W lamp is rated at 5,000 hours in normal mode and 10,000 hours in Eco mode, so a school running the projector daily can expect several years of service before a lamp change.
