3600 ANSI Lumens Laser XGA Ultra Short Throw DLP Technology Installation Projector 5.6Kg 0.65
The World’s No.1 DLP brand BenQ leads the way with futureproof interactive projectors, featuring innovative BlueCore™ 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.
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.
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 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.
BenQ LX820ST is designed with Dust Guard™ 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.The design has passed the dust chamber test standard for the international dustproof rating of IP5X.
With a fully enclosed laser light source and an innovative sealed engine design powered by BenQ Dust Guard™ 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 projec ensuring high brightness performance through years of usage.tors highly stable while
Incorporating color wheel sensors with an ingenious anti-dust accumulation feature, LX820ST 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.
LX820ST’s powerful BlueCore™ 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.
LX820ST 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. LX820ST’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.
LX820ST 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. LX820ST also features spontaneous response, requiring no wait to turn on or resume from blanking in true black for flexible performance capability.
BenQ BlueCore™ education projectors can be turned on and off instantly to significantly reduce setup time compared to other lamp-based projectors.
With a fully sealed laser light source and an innovative sealed laser engine design, BenQ BlueCore™ laser education projectors deliver 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.
Offering a big screen in short distances with a 0.63 short-throw ratio, LX820ST 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.
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.
PW02 and PT12 Compatible
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.
* BenQ exclusive annotation software QWrite™ is compatible with BenQ PointWrite™ module.
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.
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 LX820ST projectors, facilitating the free exchange of ideas and collaborative teamwork
*LX820ST/ LW820ST are compatible with QCast and QCast Mirror dongles as optional accessories.
LX820ST 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. LX820ST also supports RS-232 for reliable long-distance Installation up to 15 meters when there is no LAN infrastructure.
*Developed by Extron, IP Link driver allows device monitoring, control, and support over LAN when MediaLink controller, IP Link Ethernet control interface, or other IP Link-enabled device is installed. For more information, please visit www.extron.com/driverdownloads
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.
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.
*For more information about the tool, please contact BenQ service.
Digital Shrink is used for fine tuning the screen size via OSD menu when the image is not precisely aligned on the desired frame.
The remote control’s Quick Install hotkey sets up the projector with significant time savings for managers performing initial projector installation work.
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.
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.
