4000 Lumen, 20000 Hours, Laser LED
Uninterrupted Learning Through Long-Lasting Projection
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 ultra-short throw projection, the BenQ LH890UST utilizes the unparalleled qualities of a laser light source to achieve optimized performance, long-lasting reliability, and energy efficiency for the leading schools.
Brilliant Display of Lecture Content
LH890UST’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.
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 minimize brightness decay for long-lasting high brightness.
Expanding Classroom Possibilities
Facilitating Smart, Efficient Projector Maintenance
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. 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 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
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.
Long-Lasting Picture Quality
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.
