BenQ Dust Guard™: Maximum Dustproof Solution for Optimal Performance and Reliability




Brand-new BenQ Dust Guard™ technology incorporates the latest color wheel sensor and high-performance dust filters to block out up to 90% of dust and particles, further fortifying DX808ST with international dustproof protection rating of IP5X. Tremendously enhancing durability and reliability of BenQ projectors, Dust Guard™ significantly extends projectors’ lifetime while reducing maintenance frequency by 1/3 compared to other projectors. Guaranteeing superb lecture and presentation quality, Dust Guard™ ensures stable operation in even the dustiest environments.


BenQ Dust Guard™ Achieves Industry-Leading Dustproof Design


Studies show much higher concentration of harmful dust in indoor settings than outdoor environments, and without proper dustproof mechanisms, damaging dust and particles can substantially reduce the lifetime of projectors and inflate maintenance costs.

Caused by transportation, industrial activities or even particles in school environments, dust is the main source of damage to all projectors. BenQ projectors with Dust Guard™ technology pass a series of thorough testing in a simulated environment with large amounts of fine dust, soot, and milled cotton lint to ensure pristine performance in classrooms with high airflow and even hazardous environments with high levels of dust concentration.


Dust Filters Filter out 90% of Particles

BenQ Dust Guard™ employs advanced dust filters to prevent intrusion of PM10 level particles such as pollen and dust by up to 90%, tremendously improving protection in especially dusty environments. For added peace of mind, DX808ST features a built-in Filter Timer that reminds users to replace the filter and resets after replacement.



Anti-Dust Accumulation Sensor
Resists Dust Buildup

Incorporating color wheel sensors with an ingenious anti-dust accumulation feature, DX808ST prolongs optimal performance by repelling dust which can accumulate on traditional sensors to block the IR signal and cause flickering, abnormal colors, or even shutdown.

Expanding Classroom Possibilities with Short Throw Ratio




Unobstructed Instruction Without Space Constraints

Offering a big screen in short distance with a 0.61 short-throw ratio, DX808ST eliminates distracting shadows and glare for students and teachers to engage and collaborate freely in front of the board.


Creating Lasting Lessons with Striking Picture Quality


Uncompromised High Brightness

DX808ST produces 3,000 high ANSI lumen brightness and resolution for perfect projection performance with crisp images and sharp text even in bright lecture rooms. High brightness provides clear content under high ambient lighting, allowing lights to be kept on during classes for note taking and interactive collaboration.




Bigger Images

BenQ education projectors offer a range of resolutions and projected image sizes to meet diverse classroom needs. Featuring crisp image quality up to 120 inches, our ultra-short throw education projectors deliver increased classroom versatility at reduced costs.

Enduring Picture Perfection from DLP Technology



Long Lasting Picture Quality

With a sealed design that protects the DLP chip from dust-induced image degradation and the industrial-grade durability of DLP projection technology, BenQ education projectors are capable of maintaining long-lasting picture quality by eliminating color decay. Unlike non-DLP projectors, BenQ education projectors deliver premium picture quality equivalent to the results from brand new projectors after lamp replacement.


High Pixel Fill Factor for a Superb Viewing Experience

BenQ DLP projectors feature class-leading high fill factor, minimizing black borders around each pixel to eliminate the dreaded “screen door effect” commonly observed in non-DLP projectors. BenQ education projectors produce 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, BenQ education projectors leverage the native DLP advantage of digitally controlled micromirrors on the DMD chip. By completely toggling off reflective micromirrors to generate deep true blacks, BenQ education projectors create high native contrast ratio for sharp readability and crisp resolution at every single sub-pixel.

Enabling Interactive Learning

Interaction on Any Surface

PointWrite™ technology transforms BenQ education projectors into collaborative platforms that turn any surface into an interactive whiteboard. Seamless integration of PointWrite™ kit and QWrite software with BenQ projectors 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.

Making Collaboration Easier with BYOD



Simple and Convenient Wireless Dongle

BenQ education projectors are ready for BYOD collaboration and creating more engaging lessons via 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.

Optimizing Educational Investment


Exclusive BenQ innovation SmartEco™ technology intelligently modulates light output and perfects DLP's energy saving capabilities to increase lamp life with uncompromised brightness and exquisite picture quality. Reducing energy consumption, SmartEco™ extends lamp life up to 15,000 hours, 3X* more than without SmartEco™ technology. The Eco Blank mode further increases energy saving capability by dimming lamp power automatically to lower total power by 70% when blanking the projection.
* The lamp life under LampSave mode is three times longer than under Normal mode.



Sharp Details in Dark Scenes

BenQ’s exclusive SmartEco™ 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.

Simplifying Installation

Screen Size Adjustment

BenQ education projectors allow convenient screen size fine tuning through OSD menu to significantly save setup time, without need to physically adjust projector installation in case the sensitive short-throw image is not precisely aligned on the desired frame.




Remote Control Hotkey

Press the “Quick Install” hotkey on the remote control to setup the projector. This is a great time saver for managers performing initial projector installation work.
