Uninterrupted Learning Through Long-Lasting Projection The World’s No.1 DLP brand BenQ leads the way with futureproof projectors, featuring innovative BlueCore laser technology and superior dustproofing design for superb picture quality and maintenance-free operation. Maximising education investment and collaborative learning with ultra-short throw projection, the BenQ LH890UST utilises the unparalleled qualities of a laser light source to achieve optimised performance, long-lasting reliability, and energy efficiency for the leading schools. 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 4,000 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 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 Buildup 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 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 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 minimise brightness decay for long-lasting high brightness. 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 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. Expanding Classroom Possibilities 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. 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. *LX890UST/ LW890UST/ LH890UST is compatible with QCast dongle, QCast Mirror dongle, InstaShow as optional accessories. Facilitating Smart, Efficient Projector Maintenance 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. *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 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. Expanding Classroom Possibilities 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. Clear Images without Distortion 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 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.
