Uninterrupted Learning Through Long-Lasting Projection.
The World’s No.1 DLP brand BenQ leads the way with futureproof interactive projectors, featuring innovative BlueCoreTM laser technology and superior dustproofing design for superb picture quality and maintenance-free operation. Maximizing education investment and collaborative learning with short throw projection, BenQ LX820ST / LW820ST utilize the unparalleled qualities of a laser light source to achieve optimized performance, long-lasting reliability, energy efficiency and environmentally friendly choice for the leading school.
Precision-Aligned High-Output Laser Source
Zero-deviation alignment of BlueCore laser diodes boosts luminous flux into the light tunnel, improving light efficacy to 3,600 lumens.
Secondary Yellow-Infused Color Wheel
Dual synchronized BlueCore color wheels utilize an additive yellow segment, stimulating precise RGBY spectra for optimal chromatic performance.
Hermetically Sealed DLP Chip
Comprising over two million micromirrors that reflect pure light through the color wheel, the DLP chip is hermetically sealed to resist heat for over 100,000 hours without degradation.
Superior Dustproofing Design to Prolong Projector Lifespan
BenQ LW820ST is designed with DustGuardTM 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.
Sealed Engine for Laser Light Source
With a fully enclosed laser light source and an innovative sealed engine design powered by BenQ Dust GuardTM technology, BlueCore education projectors guarantee 20,000 hours of maintenance-free operation to prevent extra expenses on lamp replacement and maintenance. The laser light source resists brightness decay, making BenQ laser education projectors highly stable while ensuring high brightness performance through years of usage.
Brilliant Display of Lecture Content
LW820ST’s powerful BlueCoreTM laser projection utilizes a dual color wheel system to produce outstanding color performance by increasing color ratios and purity of RGBY colors, greatly enhancing color saturation and brilliancy at the same lumen output of lamp-based projectors to deliver superior viewing experiences.
Long Lasting High Brightness
LW820ST produces 3,600 ANSI lumens and superior brightness efficiency, at the same level as IFPs for clear, sharp images and text even in large, bright classrooms with lights kept on during lessons. LW820ST’s Custom Brightness function also allows manual light output adjustments in 1% increments to precisely control projection brightness to fit ambient lighting and conserve energy, as well as providing perfect edge blending for multiple projector applications.
Laser-Enabled Ultra-High Contrast
LW820ST laser projectors create strikingly clear images with stratospherically high native contrast ratio of 100,000:1 for true deep blacks, vividly rich colors, and fine subtle details. LW820ST also features spontaneous response, requiring no wait to turn on or resume from blanking in true black for flexible performance capability.
BenQ BlueCoreTM 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 BlueCoreTM laser education projectors guarantee 20,000 hours of maintenance-free operation, preventing extra expenses on lamp replacement and maintenance. The laser light source resists color and brightness decay over time, offering significantly more reliable performance after a period of operation.
Expanding Classroom Possibilities
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.
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.
Unobstructed Instruction Without Space Constraints
Offering a big screen in short distances with a 0.49 short-throw ratio, LW820ST eliminates distracting shadows and glare for students and teachers to engage and collaborate freely in front of the board.
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, BlueCore short throw education projectors deliver increased classroom versatility at reduced costs.
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.
Advanced Interactive Module Compatible
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 LW820ST projectors, facilitating the free exchange of ideas and collaborative teamwork.
Facilitating Smart, Efficient Projector Maintenance
Control System Compatibility
LW820ST 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. LW820ST 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 BenQ projectors that are on the same local network via LAN (up to 253 projectors,) deploying the latest updates to all devices at once. This new application can upgrade firmware with a friendlier interface.
Clear Images without Distortion
Digital Shrink is used for fine tuning the screen size via OSD menu when the image is not precisely aligned on the desired frame.
With industry-leading high contrast, BenQ education projectors utilize advanced DLP-optimized optical lens systems to provide precise readability and crisp resolution for every single sub-pixel.
