Ultra-Sharp Images in a Short Distance Designed for disruption-free learning in small-sized classrooms, the MX816ST offers a 78” XGA picture in only 1 meter with a 0.6 ultra short-throw ratio. Together with 13000:1 ultra-sharp contrast ratio and 3000 ANSI lumen brightness, this Projectorector has the most dynamic image quality to offer! World-Leading SmartEco Technologyfor a Greener Environment As the first DLP brand to incorporate Philips’ ImageCare technology into its Projectorector lamp system, BenQ has taken a further leap, developing its own SmartEco Technology to perfect what DLP can do for energy saving in the 21st century classroom. Built with this brand new invention, the MX816ST brings together uncompromised brightness, exquisite picture quality and optimized lamp life through innovative features. Eco Blank Mode The Eco Blank mode allows teachers to blank the Projectorection screen whenever they need to direct their students’ focus back on them – or simply when the Projectorector is not in use. When activated, this special feature dims the lamp power automatically, lowering the total power consumption by up to 70%. Long Lamp Life at up to 5000 hours Enjoy a lamp life performance of up to 5000 hours in Eco mode– longer lamp life expectancy of average Projectorector lamps on the market! This certainly lowers the number of lamp changes and keeps all maintenance to a minimum. *Lamp life results will vary depending on environmental conditions and usage Thoughtful Features Built-in 10W Big Audio Power The MX816ST features one built-in 10W speaker to help enrich every lesson with top quality audio performances. Closed Captioning Display subtitles in video content without the need for an external closed-captioning device with the MX816ST.
