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. Creating Lasting Lessons with Striking Picture Quality BenQ BlueCore Laser Technology Superior Bright Precision-Aligned High-Output Laser Source Zero-deviation alignment of BlueCore laser diodes boosts luminous flux into the light tunnel, improving light efficacy to 3600 lumens. Superior Performance Secondary Yellow-Infused Colour Wheel Dual synchronised BlueCore colour wheels utilise an additive yellow segment, stimulating precise RGBY spectra for optimal chromatic performance. Superior Durability Hermetically Sealed DLP Chip Comprising over two million micromirrors 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 Dustproofing 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. 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 Resists Dust Buildup Incorporating colour 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 colours, or even shutdown. Brilliant Display of Lecture Content LW820ST's powerful BlueCore laser projection utilises 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 LW820ST 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. LW820ST 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 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. 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. 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 colour and brightness decay over time, offering significantly more reliable performance after a period of operation. Expanding Classroom Possibilities 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. 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, 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. (* BenQ exclusive annotation software QWrite is compatible with BenQ PointWrite module.) 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.) Facilitating Smart, Efficient Projector Maintenance Control System Compatibility LW890UST 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. LW890UST 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. Centralised Control with BenQ MDA Software BenQ Multiple Display Administrator (MDA) software enables powerful centralised monitoring, control, and power scheduling across the school’s projector network from a single computer, offering full access and control over every projector directly. Centralised Upgrade Application 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. Simplified Image Alignment and Perfect Installation 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. 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. Enduring Picture Perfection from the World’s No.1 DLP Brand BenQ Unmatched Readability With industry-leading high contrast, BenQ education projectors utilise advanced DLP-optimised 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 colour 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.
