With a throw ratio of 0.28–0.37:1, it projects a large, evenly illuminated image from less than one metre from the wall – presenters and pupils never stand in their own shadow. The WXGA resolution of 1,280 × 800 pixels displays 16:10 laptop content edge to edge, without black bars. With 3,500 ISO lumens, presentations remain easy to read even in rooms with normal ceiling lighting.\u003c\/p\u003e\n\n\u003ch3\u003eBenefits and special features\u003c\/h3\u003e\n\n\u003cul\u003e\n\u003cli\u003e\u003cspan\u003e3,500 ISO lumens – equal white and colour brightness thanks to 3LCD technology\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eUltra short throw lens (TR 0.28–0.37:1) – no shadows cast by presenters\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eWXGA 1,280 × 800 – 16:10 format without letterboxing for standard laptops\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003e3× HDMI 2.0 – several sources connected at the same time\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eLAN with PJLink, Crestron, AMX and SNMP – central network control and monitoring\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eRS-232 for room control integration (on\/off, input, brightness, status)\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eDirect Power On – starts automatically as soon as mains power is applied\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003e36-month warranty\u003c\/span\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eApplications: what the Epson EB-685W is ideal for\u003c\/h3\u003e\n\n\u003ch3\u003eClassrooms and teaching rooms\u003c\/h3\u003e\n\u003cp\u003eThe ultra short throw lens of the EB-685W allows wall mounting directly above the board or placement on a table at the front of the classroom. Teachers never stand in the beam of light – they can interact freely with the projected content at any time. 3,500 ISO lumens reliably outshine normal room lighting, so there is no need to lower the blinds.\u003c\/p\u003e\n\n\u003ch3\u003eTraining rooms and meetings\u003c\/h3\u003e\n\u003cp\u003eWith three HDMI inputs, a laptop, desktop PC and another device can stay connected at the same time – switching between presenters works without hunting for cables. The 16:10 format displays Office presentations and spreadsheets in full. The LAN connection with PJLink protocol enables central control and monitoring via the school network, so teachers don't have to search for the remote control.\u003c\/p\u003e\n\n\u003ch3\u003ePicture and sound quality\u003c\/h3\u003e\n\n\u003cp\u003eThe EB-685W uses Epson's proven 3LCD technology with a 0.59\" chip. The native WXGA resolution (1,280 × 800 pixels) matches the 16:10 format of current laptops – presentations, spreadsheets and web content are displayed without scaling losses. With a contrast ratio of 14,000:1, text and diagrams stand out clearly. As a 3LCD projector, the EB-685W delivers identical white and colour brightness of 3,500 ISO lumens; with single-chip DLP projectors, colour brightness can be significantly lower than the stated white brightness.\u003c\/p\u003e\n\n\u003cp\u003eThe built-in 16 W mono speaker is sufficient for regular lessons and training rooms.

Thanks to the fixed, significantly upward image offset, the projector can be placed just above or below the projection surface without protruding into the image. UST projectors should always be aligned exactly parallel to the wall – the digital keystone correction (±3° vertical\/horizontal) is only intended for fine-tuning minimal residual deviations and is no substitute for proper mechanical alignment.\u003c\/p\u003e\n\n\u003cp\u003eUST projectors are typically placed directly below the projection surface or wall-mounted above the screen. Many models also support upside-down ceiling operation – please refer to the manual for the mounting options of the respective model.\u003c\/p\u003e\n\n\u003cp\u003eThe calculated throw distances are based on the manufacturer's throw ratio and are intended as guide values. As the measuring points (e.g. from the centre of the lens vs. the front of the housing) often vary between data sheets, calculations accurate to the centimetre cannot always be guaranteed.\u003c\/p\u003e\n\n\u003ctable style=\"border-collapse:collapse;width:100%;font-size:0.9em;\"\u003e\n\u003cthead\u003e\n\u003ctr style=\"background-color:#068E52;color:#fff;\"\u003e\n\u003cth style=\"padding:8px;text-align:left;color:#fff;\"\u003eImage size\u003c\/th\u003e\n\u003cth style=\"padding:8px;text-align:left;color:#fff;\"\u003eImage width\u003c\/th\u003e\n\u003cth style=\"padding:8px;text-align:left;color:#fff;\"\u003eImage height\u003c\/th\u003e\n\u003cth style=\"padding:8px;text-align:left;color:#fff;\"\u003eThrow distance (approx.)\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding:8px;border-bottom:1px solid #c2e4c8;\"\u003e80\"\u003c\/td\u003e\n\u003ctd style=\"padding:8px;border-bottom:1px solid #c2e4c8;\"\u003e171 cm\u003c\/td\u003e\n\u003ctd style=\"padding:8px;border-bottom:1px solid #c2e4c8;\"\u003e107 cm\u003c\/td\u003e\n\u003ctd style=\"padding:8px;border-bottom:1px solid #c2e4c8;\"\u003e48–63 cm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"background:#E6FFE9;\"\u003e\n\u003ctd style=\"padding:8px;border-bottom:1px solid #c2e4c8;\"\u003e100\"\u003c\/td\u003e\n\u003ctd style=\"padding:8px;border-bottom:1px solid #c2e4c8;\"\u003e214 cm\u003c\/td\u003e\n\u003ctd style=\"padding:8px;border-bottom:1px solid #c2e4c8;\"\u003e133 cm\u003c\/td\u003e\n\u003ctd style=\"padding:8px;border-bottom:1px solid #c2e4c8;\"\u003e60–79 cm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding:8px;\"\u003e120\"\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003e256 cm\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003e160 cm\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003e72–95 cm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\n\u003cp\u003eIn the box: Epson EB-685W, remote control, power cable, batteries.\u003c\/p\u003e\n\n\u003ch3\u003eLight source and operation\u003c\/h3\u003e\n\n\u003ctable style=\"border-collapse:collapse;width:100%;font-size:0.9em;\"\u003e\n\u003cthead\u003e\n\u003ctr style=\"background-color:#068E52;color:#fff;\"\u003e\n\u003cth style=\"padding:8px;text-align:left;color:#fff;\"\u003eOperating mode\u003c\/th\u003e\n\u003cth style=\"padding:8px;text-align:left;color:#fff;\"\u003eLamp hours\u003c\/th\u003e\n\u003cth style=\"padding:8px;text-align:left;color:#fff;\"\u003eYears (2 hrs\/day)\u003c\/th\u003e\n\u003cth style=\"padding:8px;text-align:left;color:#fff;\"\u003eYears (8 hrs\/day)\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding:8px;border-bottom:1px solid #c2e4c8;\"\u003eNormal\u003c\/td\u003e\n\u003ctd style=\"padding:8px;border-bottom:1px solid #c2e4c8;\"\u003e5,000 h\u003c\/td\u003e\n\u003ctd style=\"padding:8px;border-bottom:1px solid #c2e4c8;\"\u003e7 years\u003c\/td\u003e\n\u003ctd style=\"padding:8px;border-bottom:1px solid #c2e4c8;\"\u003e1.5 years\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"background:#E6FFE9;\"\u003e\n\u003ctd style=\"padding:8px;border-bottom:1px solid #c2e4c8;\"\u003eEco\u003c\/td\u003e\n\u003ctd style=\"padding:8px;border-bottom:1px solid #c2e4c8;\"\u003e10,000 h\u003c\/td\u003e\n\u003ctd style=\"padding:8px;border-bottom:1px solid #c2e4c8;\"\u003e13.5 years\u003c\/td\u003e\n\u003ctd style=\"padding:8px;border-bottom:1px solid #c2e4c8;\"\u003e3.5 years\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding:8px;\"\u003eDynamic\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003e9,000 h\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003e12.5 years\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003e3 years\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\n\u003cp\u003eIn Eco mode, the noise level drops from 35 dB to 30 dB – a clearly measurable difference that noticeably improves quiet lessons.
