Benq LH890UST 4000lms 1080P Conference Room Projector White

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 color 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 colors, or even shutdown.

Brilliant Display of Lecture Content

LH890UST’s powerful 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.

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.
