Designed for disruption-free learning in small-sized classrooms, the MX850UST offers a 81" XGA picture in only 0.74 meters with a 0.4 ultra short-throw ratio. Together with 13000:1 ultra-sharp contrast ratio and 2500 ANSI lumen brightness, this projector has the most dynamic image quality to offer
World-Leading SmartEco Technology for a Greener Environment
Schools today face the challenge of introducing new technologies and teaching tools into their classrooms and cut down on energy costs. In the effort to help schools meet the learning needs of their students as well as the green goals set by the school district, BenQ has collaborated with Philips Lighting in developing the perfect solution - the SmartEco Technology.
The SmartEco Technology brings a new way of operating the projector lamp system. Intuitive to use and environmentally friendly, this technology brings together the finest picture quality and maximum energy saving. With the SmartEco Technology, students and teachers get to make the most out of their classroom experience - and schools reduce the total cost of ownership with extended lamp life and lowered maintenance needs.
Eco Blank Mode
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 70%.
Smart Eco Mode
The Smart Eco mode is designed to use only the exact amount of lamp power a projector needs to deliver the best contrast performance. With this feature, schools get to provide students and teachers uncompromised projection quality and reduce the total cost of ownership by extending the lamp life and lowering power consumption.
No Source Detected Mode
There will be times when a projector is turned on without a display source, such as a classroom PC or notebook. To avoid a projector from running with full lamp power, BenQ created the No Source Detected Mode to lower the projector lamp brightness to 30% after the projector has remained unconnected to a display source for more than three minutes.
The Perfect Sound Solution
Built-in 20W Big Audio Power
The MX850UST features two built-in 10W speakers to help enrich every lesson with top quality audio performances. These speakers are sealed and secured within the projector housing by BenQ's anti-shake design to ensure projection stability at all times.
Microphone Input Support
With the microphone input, teachers get to reach every student with straining their voice. All they need to do is plug in the microphone or microphone headset to get started
