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.

Offering a big screen in short distance with a 0.61 short-throw ratio, MX825STH eliminates distracting shadows and glare for students and teachers to engage and collaborate freely in front of the board.

Optimizing Educational Investment

Long-lamp Life

The exclusive BenQ innovation SmartEcoTM 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, SmartEcoTM extends lamp life up to 15,000 hours, 3X* more than without SmartEcoTM technology.

And 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.

Key features

Uncompromised High Brightness

MX825STH produces 3,500 high ANSI lumen brightness and resolution for perfect projection performance with 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 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.

Enduring Picture Perfection from DLP Technology

With 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 result from brand new projectors after lamp replacement.

High DLP Pixel Fill Factor for 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.

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.

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.

Easy Set-up and Maintenance

Unobstructed Instruction Without Space Constraints

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.

Anti-Dust Accumulation SensorResists Dust Buildup

Incorporating color wheel sensors with an ingenious anti-dust accumulation feature, MX825STH 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.

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.

Frequently asked questions

What is PointWrite and what does it let you do on the MX825STH?

PointWrite is BenQ's interactive whiteboard technology, which turns any projection surface into a collaborative touch surface using pens or fingers. Combined with QWrite software, two PointWrite projectors can even be linked to double the interactive projection surface.

How close to the screen can the MX825STH be mounted?

It has a 0.61 short-throw ratio, so a 100" XGA (4:3) image roughly 2.03m wide can be projected from around 1.24m away - eliminating distracting shadows and glare as presenters stand close to the board.

How bright is the MX825STH and what resolution does it use?

It produces 3,500 ANSI lumens at XGA (1024x768) resolution, with a high native contrast ratio from its DLP chip for crisp, readable text even under bright lecture-room lighting.

How long does the lamp last?

BenQ's SmartEco technology extends lamp life to up to 15,000 hours - three times longer than without it - and Eco Blank mode cuts total power by 70% when the projection is blanked.

What control systems does the MX825STH support?

It's compatible with Crestron, AMX and PJ-Link control systems, making it straightforward to integrate and centrally manage alongside other third-party AV equipment.

How quickly can TopAV deliver the MX825STH?

It's in stock at TopAV, so it dispatches within 2 working days. At £726.00 inc VAT it qualifies for free standard UK delivery.
