BenQ MX825ST

3300 lumens XGA projector for advanced interactive instruction 

Expand classroom possibilities with the Short Throw Ratio MX825ST. Create lasting lessons with striking picture quality from the high brightness 3300 lumens, bigger images, and industrial-grade durability of DLP projection technology.

PointWrite™ technology, with enhanced multi-touch capability for pens or fingers, enables interactive learning. 

Meanwhile, an anti-dust accumulation feature prolongs performance, and BenQ's exclusive SmartEcoTM technology increases lamp life with uncompromised brightness and exquisite picture quality.

Installation is simple with remote control hotkey and screen size adjustment.

This projector features:

  • Short-throw ratio
  • DLP technology for long-lasting picture perfection
  • PointWrite Interactive Solution Compatible


  • Ingenious Anti-Dust Accumulation Feature: prolongs optimal performance by rejecting dust which can accumulate on traditional sensors to block the IR signal and cause flickering, abnormal colors, or even shutdown.
  • Big screen in short distance with a 0.61 short-throw ratio: eliminates distracting shadows and glare for students and teachers to engage and collaborate freely in front of the board.
  • 3,300 high ANSI lumen brightness: delivers crisp images and sharp text even in bright lecture room. High brightness provides clear content under high ambient lighting, allowing lights to be kept on during classes for note taking and interactive collaboration.
  • Crisp image quality up to 120 inches: provides a range of resolutions and projected image sizes to meet diverse classroom needs. The MX825ST ultra-short throw education projector delivers increased classroom versatility at reduced costs.
  • Long Lasting Picture Quality: eliminates color decay thanks to the sealed design that protects the DLP chip from dust-induced image degradation, and the industrial-grade durability of DLP projection technology. 
  • High DLP Pixel Fill Factor: provides a superb viewing experience by minimizing black borders around each pixel to eliminate the dreaded "screen door effect" commonly observed in non-DLP projectors. This leads to superior definition and clarity in small-size text and fine details, for beautifully rendered images instead of pixelated graphics.
  • Crisp Readability via High Contrast Ratio: ideal for text, numbers, and tables widely used in instruction. The DLP advantage of digitally controlled micro-mirrors on the DMD chip creates high native contrast ratio for sharp readability and crisp resolution at every single sub-pixel.
  • Interaction on Any Surface: PointWrite™ technology transforms this education projector into a collaborative platform that turns any surface into an interactive whiteboard. Seamless integration of PointWrite™ kit and QWrite software with the projector encourages a truly collaborative learning environment where students and teachers work together using intuitive templates along with annotation tools.
  • Multi-Touch & Multi- Screen Drawing: With enhanced multi-touch capability for pens or fingers, two PointWrite™ projectors can be used in conjunction to double the interactive projection surface, creating vast new opportunities for interactive learning in modern digital classrooms. In QWrite Whiteboard Mode, teachers can also run different applications or display, view, and annotate across two surfaces.
  • Intuitive Setup: Reliably accurate in any ambient lighting, PointWrite™ auto calibrates and saves its settings immediately when plugged into a computer’s USB port, remaining ready with no manual configuration or complicated training for teachers.
  • Windows Gesture Support: PointWrite™ projectors support intuitive Windows gestures such as zooming in and out or scrolling while browsing webpages, pictures or Google Maps. All multi-touch commands and gestures are supported for Windows 8 or above and future applications.
  • Simple and Convenient Wireless Dongle: Collaborate and create more engaging lessons via the QCast wireless dongle that allows up to 4 participants to stream content from smart devices or computers to the big screen, displaying them in 4 split screens.
  • Increased lamp life with uncompromised brightness and exquisite picture quality: SmartEcoTM technology reduces energy consumption and triples lamp life up to 15,000 hours. And Eco Blank mode further increases energy saving capability by dimming lamp power automatically to lower total power by 70% when blanking the projection.
  • Sharp Details in Dark Scenes: SmartEcoTM Technology ingeniously adjusts light output based on content, enhancing contrast to produce richer blacks and the best possible picture quality, especially important for detailed and dynamic dark scenes such as astronomy courses.
  • LAN Control Compatibility: BenQ education projectors are compatible with Creston, AMX, and PJ Link control systems for convenient system integration with various third-party components and cost reduction via central maintenance of multiple projectors.
  • Centralized Multiple Display Management: With enhanced multi-touch capability for pens or fingers, two PointWrite™ projectors can be used in conjunction to double the interactive projection surface, creating vast new opportunities for interactive learning in modern digital classrooms. In QWrite Whiteboard Mode, teachers can also run different applications or display, view, and annotate across two monitors.
  • Screen Size Adjustment: allows convenient screen size fine tuning through OSD menu to significantly save setup time, without the need to physically adjust projector installation in case the sensitive short-throw image is not precisely aligned on the desired frame.
  • Remote Control Hotkey: "Quick Install" hotkey on the remote control sets up the projector. This is a great time saver for managers performing initial projector installation work.
