The BenQ LW820ST BlueCore Laser Projector makes effective use of unparalleled qualities of a laser light source to achieve optimized performance, long-lasting reliability, energy efficiency and environmentally friendly choice for the leading school. This WXGA projector offers innovative BlueCore laser technology and superior dust-proofing design for superb picture quality and maintenance-free operation. Maximize education investment and collaborative learning with short throw projection brought by the LW820ST projector.

BenQ BlueCore Laser Technology for pure color

Powerful BlueCore laser projectors employ dual color wheel systems to unleash outstanding color performance by increasing color ratios and purity of RGBY color, greatly enhancing color saturation and brilliancy at the same lumen output of lamp-based projectors to deliver superior viewing experiences.

A precision-aligned high-output laser source

Zero-deviation alignment of BlueCore laser diodes boosts luminous flux into the light tunnel, improving light efficacy to 5,000 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 dust-proofing design to prolong projector lifespan

BenQ LW820ST is designed with Dust GuardTM 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.

*Dust chamber test standard: JIS Class IP5X

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.

Anti-dust accumulation sensor

Incorporating color wheel sensors with an ingenious anti-dust accumulation feature, LW820ST prolongs optimal performance by rejecting dust which can accumulate on traditional sensors to block the IR signal and cause flickering, abnormal colors, or even shut down.

BlueCoreTM laser projection

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 brilliance 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.
 

Long Lasting High Brightness

Laser-enabled ultra-high contrast

LW820ST laser projectors create strikingly clear images with a 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.

Instant power-on

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

Multi-Touch with pens and multi-screen drawing

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 7 or above and future applications.

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.

*LX820ST/ LW820ST are compatible with QCast and QCast Mirror dongles as optional accessories.

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 provides powerful centralized multiple-projector management, including automated opening and closing procedures for public spaces, remotely controlled power on and off, and scheduling for institutions and corporations.
 

Centralized upgrade tool for multiple projector maintenance

Administrator 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.

*For further information about the tool, please contact BenQ service for support.

Digital Shrink 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.
 

Remote control hotkey

The remote control’s Quick Install hotkey sets up the projector with significant time savings for managers performing initial projector installation work.

Unmatched readability

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.
 

Long-lasting picture quality

With industrial-grade durability from DLP technology, BenQ education projectors maintain long-lasting picture perfection by eliminating color decay. Unlike non-DLP projectors, BenQ DLP education projectors look brand-new after lamp replacement. And with over two million micromirrors and minimal heat buildup, the DLP chip endures over 100,000 hours without degradation.
