BenQ - LH890UST - Education Projector

Uninterrupted Learning Through Long-Lasting Projection

• Ultra short-throw ratio
• Laser technology for superb image quality
• IP5X dustproof mechanism reducing maintenance costs

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.

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 121 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.

Multi-Touch with Pens and Multi-Screen Drawing
PointWrite™ 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.
*QWrite™ is BenQ exclusive annotation software is compatible with BenQ PointWrite™ module.
