BenQ LW890UST

Creating Lasting Lessons with Striking Picture Quality

Revolutionary Laser Technology

Anti-Dust Accumulation Sensor Resists Dust Buildup

Incorporating 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 Content

LW890UST’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.

Laser-Enabled Ultra-High Contrast

LW890UST 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 Brightness

LW890UST 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.

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.

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.
