BenQ LW890UST

4000 lumens WXGA education projector with long-lasting projection

Expand classroom possibilities with the ultra-short throw ratio LW890UST. Create lasting lessons with striking picture quality from the high brightness 4000 lumens, bigger images, and industrial-grade durability of DLP projection technology.

PointWrite™ technology, with multi-touch for pens and multi-screen drawing, enables interactive learning. 

Meanwhile, DustGuard^TM technology, as well as an anti-dust accumulation feature, protect the laser bank to prolong projector lifespan.

Installation is simple and efficient with an ultra-short throw projector wall mount (included), or even by using an existing wall mount, thanks to the three-way adjustment knob.

This projector's main features are:

• Ultra-short throw ratio
• BlueCore laser technology for superb image quality (see below)
• IP5X dustproof mechanism reducing maintenance costs

Zero-deviation alignment of BlueCore laser diodes boosts luminous flux into the light tunnel, improving light efficacy for superior brightness.

Dual synchronized BlueCore color wheels utilize an additive yellow segment, stimulating precise RGBY spectra for optimal chromatic performance.

Comprising over two million micro-mirrors that reflect pure light through the color wheel, the DLP chip is hermetically sealed to resist heat for over 100,000 hours without degradation, offering superior durability.

• Outstanding color performance: BlueCore^TM laser projection uses a dual color wheel system to increase 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 contrast: creates 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.

• Long lasting 4,000 ANSI lumen brightness: delivers crisp images and sharp 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.

• Instant Power-On: can be turned on and off instantly to significantly reduce setup time.

• 20,000 hours of maintenance-free operation: fully sealed laser light source and innovative sealed laser engine design prevent extra expenses on lamp replacement and maintenance. The laser light source resists color and brightness decay over time.

• Bigger images in short distance with 0.24 ultra-short throw ratio: projector can be mounted on the wall directly above the screen, eliminating distracting shadows and glare. Featuring crisp image quality up to 100 inches, the LW890UST delivers increased classroom versatility at reduced costs.

• Interaction on Any Surface: PointWrite™ technology works on any flat surface, so no expensive digital whiteboard or additional equipment is necessary. Images can be projected onto a wall for multiple students to easily share and write on the same screen.

• Multi-Touch & Multi- Screen Drawing: PointWrite™ 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. (*QWrite™, BenQ exclusive annotation software, is compatible with BenQ PointWrite™ module.)

• Intuitive Setup: PointWrite™ auto calibrates and saves its settings immediately when plugged into a computer’s USB port, remaining ready with no manual configuration or complicated training for teachers.

• 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 (49 feet) when there is no LAN infrastructure.

• Centralized Control with Multiple Display Administrator Software: BenQ's 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 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. 

• Streamlined Wall Mount Alignment: included wall mount features an installation chart and ruler for perfect screen alignment and image position in the classroom. Even simpler, an existing wall mount can be used with the three-way adjustment knob located in front of the projector.

• Long-lasting picture quality: industrial-grade durability DLP technology eliminates color decay. With over two million micromirrors and minimal heat buildup, the DLP chip endures over 100,000 hours without degradation.

• Superior dust-proofing design to prolong projector lifespan: DustGuard^TM technology, including sealed laser modules, protects the laser bank. This lock-and-key design hermetically seals the laser engine from dust to prolong projector lifespan.

• Ingenious anti-dust accumulation feature: 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.
