SmartEco lamp technology takes your lamp up to 10,000 hours! Now with up to 10,000 hour lamp life that equates to up to 10+ years in use, the MX819ST brings together uncompromised brightness, exquisite picture quality and 80% lamp power savings. The Eco Blank mode allows teachers to blank the projection screen whenever they need to direct their students' focus back on them - or simply when the projector is not in use. When activated, this special feature dims the lamp power automatically, lowering the total power consumption by up to 80%. No Source Detected Mode automatically switches the projector to Eco Blank Mode if the projector is turned on for over three minutes without a display source, eliminating unnecessary energy waste and prolonging the life of the projector lamp. Get better contrast and blacker blacks with a 13000:1 contrast ratio. When inactive, the MX819ST complies with 2013 EU standards by keeping power consumption to a minimum using less than 0.5 W on standby, extending lamp life and reducing energy costs. Blu-ray Full HD 3D Supported! BenQ MX819ST is built with the latest DLP technology to support 3D functionality. Zero Eye-Blinding Lights! The short-throw projection distance keeps the projector light from shining directly into your eyes, allowing you to keep your focus on your audience. Zero Disruptions!

With a projection distance this close, you and your audience can move freely without worrying about obstructions between the projector and the screen! LAN Control with Crestron and PJ-Link. LAN Control is designed to help IT managers perform day-to-day projector maintenance and repair tasks efficiently and effectively - offering them full access and control over every projector directly from their workstations.
