Interactive capabilities require the optional PW40U PointWrite™ Interactive Kit. Touch capabilities require the optional PT20 PointWrite™ Touch Module

Precision-Aligned High-Output Laser Source

Zero-deviation alignment of BlueCore laser diodes boosts luminous flux into the light tunnel, improving light efficacy to 4,000 lumens.

Secondary Yellow-Infused Colour Wheel

Dual synchronized BlueCore colour wheels utilize an additive yellow segment, stimulating precise RGBY spectra for optimal chromatic performance.

Hermetically Sealed DLP Chip

Comprising over two million micro-mirrors that reflect pure light through the colour wheel, the DLP chip is hermetically sealed to resist heat for over 100,000 hours without degradation.

Superior Dust-proofing Design to Prolong Projector Lifespan

BenQ LH890UST is designed with DustGuard™ technology including sealed laser modules to protect the laser bank. This lock-and-key design hermetically seals the laser engine from dust to prolong projector lifespan.

Anti-Dust Accumulation Sensor Resists Dust Build-up

Incorporating colour wheel sensors with an ingenious anti-dust accumulation feature, LH890UST prolongs optimal performance by rejecting dust which can accumulate on traditional sensors to block the IR signal and cause flickering, abnormal colours, or even shutdown.

Brilliant Display of Lecture Content

LH890UST’s powerful BlueCore™ laser projection utilizes a dual colour wheel system to produce outstanding colour performance by increasing colour ratios and purity of RGBY colours, greatly enhancing colour saturation and brilliancy at the same lumen output of lamp-based projectors to deliver superior viewing experiences.

Laser-Enabled Ultra-High Contrast

LH890UST laser projectors create strikingly clear images with stratospherically high native contrast ratio of 100,000:1 for true deep blacks, vividly rich colours, and fine subtle details. LH890UST also features spontaneous response, requiring no wait to turn on or resume from blanking in true black for flexible performance capability.

Long Lasting High Brightness

LH890UST produces 4,000 ANSI lumens and superior brightness efficiency, at the same level as IFPs for clear, sharp images and text even in large, bright classrooms. High brightness allows lights to be kept on during lessons, and sealed laser banks prevent dust entry to minimize brightness decay for long-lasting high brightness.

Instant Power-On

BenQ BlueCore™ education projectors can be turned on and off instantly to significantly reduce setup time compared to other lamp-based projectors.

20,000 Hour Long-Lasting Performance

With a fully sealed laser light source and an innovative sealed laser engine design, BenQ BlueCore™ laser education projectors guarantee 20,000 hours of maintenance-free operation, preventing extra expenses on lamp replacement and maintenance. The laser light source resists colour and brightness decay over time, offering significantly more reliable performance after a period of operation.

Ultra-Short Throw

Ultra-short throw projectors can be mounted inches the wall directly above the screen, eliminating distracting shadows and glare for students and teachers to engage and collaborate freely in front of the board.

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 100 inches, our ultra-short throw education projectors deliver increased classroom versatility at reduced costs.

Create Interaction on Any Surface

PointWrite™ technology works on any flat surface, so no expensive digital whiteboard or additional equipment is necessary. With the PointWrite™ module (sold separately), images can be projected onto a wall for multiple students to easily share and write on the same screen, creating vast new opportunities for classroom interactivity and enabling possibilities for modern digital classrooms.

Multi-Touch with Pens and Multi-Screen Drawing

PointWrite™ projectors offer multi-user capability, and two PointWrite™ projectors can be used to double the projection surface. With QWrite* Whiteboard Mode, teachers can run different applications or display, view, and annotate across two monitors. (*QWrite™ is BenQ exclusive annotation software compatible with BenQ PointWrite™ module (sold separately).)

Intuitive Setup

PointWrite™ (sold separately) automatically calibrates and saves its settings the moment it is plugged into a computer’s USB port. PointWrite™ then remains ready with no manual configuration or complicated training for teachers needed. Additionally, LH890UST’s interactive sensor guarantees reliable auto-calibration in any ambient lighting.

Advanced Interactive Module Compatible

A modular design allowing schools the flexibility of adding interactivity to classrooms with future investment, the new BenQ PointWrite™ interactive module PW40U provides truly collaborative learning environments where students and teachers work together using intuitive templates along with QWrite™ software, all with one-time calibration and set-up driver installation conveniences. (* PW40U is an optional interactive module for LH890UST)

Multiple Choices for Wireless Compatibility

For engaging and intuitive lessons, teachers and students can bring their own smart devices and computers to stream documents, images, and even Full HD videos to LH890UST projectors, facilitating the free exchange of ideas and collaborative teamwork. (* LH890UST is compatible with QCast dongle, QCast Mirror dongle, InstaShow as optional accessories.)

Control System Compatibility

LH890UST is widely compatible with leading projector control systems including Crestron, AMX, PJ Link, and Extron IP Link for network control via LAN, making it simple to integrate into educational network infrastructures. LH890UST also supports RS-232 for reliable long-distance Installation up to 15 meters when there is no LAN infrastructure.

Centralized Control with BenQ MDA Software

BenQ Multiple Display Administrator (MDA) software enables powerful centralized monitoring, control, and power scheduling across the school’s projector network from a single computer, offering full access and control over every projector directly.

Centralized Upgrade Tool for Multiple Projector Maintenance

Administrators can centrally upgrade firmware on multiple networked BenQ education projectors on the same local network via LAN (up to 253 projectors), deploying the latest updates to all devices at once. This new tool can upgrade firmware types including TI IC, MCU IC, LAN IC, and Ballast IC, with a friendlier user interface.

Streamlined Wall Mount Alignment

For efficient professional installation, our ultra-short throw projector wall mount features an installation chart and ruler for perfect screen alignment and image position in the classroom. Even simpler, using an existing wall mount without uninstallation, a three-way adjustment knob is located in front of the projector for cleanly installed, absolutely square screens.

Digital Shrink

Digital Shrink is used for fine tuning the screen size via OSD menu when the image is not precisely aligned on the desired frame.

Corner Fit Correction

Corner Fit provides individual adjustment of each corner for perfect fit and alignment onto restricted or uneven spaces.

Enduring Picture Perfection from the World’s No.1 DLP Brand BenQ

With industry-leading high contrast, BenQ education projectors utilize advanced DLP-optimised optical lens systems to provide precise readability and crisp resolution for every single sub-pixel. With industrial-grade durability from DLP technology, BenQ education projectors maintain long-lasting picture perfection by eliminating colour decay. Unlike non-DLP projectors, BenQ DLP education projectors look brand-new after lamp replacement. And with over two million micro-mirrors and minimal heat build-up, the DLP chip endures over 100,000 hours without degradation.
