Thanks to the EB-685W's ultra-short distance lens, you can project large images from a very short distance without creating shadows or glare. With a brightness of 3,500 lumens, HD-ready WXGA resolution, a contrast ratio of 14,000:1 and HDMI, you'll enjoy crisp, clear images. With the same high white and colour brightness thanks to Epson's 3LCD technology, the projectors deliver vivid, natural colours even in daylight, and with up to 10,000 hours of lamp life in economy mode and high reliability, you can project images for even longer. With the split screen function, you can display two different contents simultaneously without compromising on quality. With the moderator function, you can control the display of the content. With the optional Epson document camera, you can easily display templates and 3D objects with incredible detail.
