BenQ LW890UST data projector Ultra short throw projector 4000 ANSI lumens DLP WXGA (1280x800) 3D White

Interactive Laser Projector with Ultra Short Throw, WXGA | LW890USTUninterrupted Learning Through Long-Lasting ProjectionThe 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 ultra-short throw projection, the BenQ LW890UST utilizes the unparalleled qualities of a laser light source to achieve optimized performance, long-lasting reliability, and energy efficiency for the leading schools.Superior BrightPrecision-Aligned High-Output Laser SourceZero-deviation alignment of BlueCore laser diodes boosts luminous flux into the light tunnel, improving light efficacy to 4,000 lumens.Superior PerformanceSecondary Yellow-Infused Color WheelDual synchronized BlueCore color wheels utilize an additive yellow segment, stimulating precise RGBY spectra for optimal chromatic performance.Superior DurabilityHermetically Sealed DLP ChipComprising 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 LifespanBenQ LW890UST 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.Anti-Dust Accumulation Sensor Resists Dust BuildupIncorporating color wheel sensors with an ingenious anti-dust accumulation feature, LW890UST 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.Brilliant Display of Lecture ContentLW890UST 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.Laser-Enabled Ultra-High ContrastLW890UST 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.LW890UST also features spontaneous response, requiring no wait to turn on or resume from blanking in true black for flexible performance capability.Long Lasting High BrightnessLW890UST 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 minimize brightness decay for long-lasting high brightness.Instant Power-OnBenQ 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 PerformanceWith 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 PossibilitiesUltra-Short ThrowUltra-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 ImagesBenQ 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 SurfacePointWrite 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 DrawingPointWrite 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.Intuitive SetupPointWrite automatically calibrates and saves its settings the moment it is plugged into a computer s USB port. PointWrite then remains ready with no manual configuration or complicated training for teachers needed. Additionally, LW890UST s interactive sensor guarantees reliable auto-calibration in any ambient lighting. Advanced Interactive Module CompatibleA modular design allowing schools the flexibility of adding interactivity to classrooms with future investment, the new BenQ PointWrite interactive module PW40U provides truly collaborative learning environments where students and teachers work together using intuitive templates along with QWrite software, all with one-time calibration convenience.Multiple Choices for Wireless CompatibilityFor 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 LW890UST projectors, facilitating the free exchange of ideas and collaborative teamwork.Facilitating Smart, Efficient Projector MaintenanceControl System CompatibilityLW890UST 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.Centralized Control with BenQ MDA SoftwareBenQ 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 MaintenanceAdministrators 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 PossibilitiesStreamlined Wall Mount AlignmentFor 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. Long-Lasting Picture QualityWith 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.
