Resists Dust Buildup

An ingenious anti-dust accumulation color wheel sensor repels debris from blocking the IR signal and causing flickering, abnormal colors, or even shutdown.



Sealed Laser Light Source

The laser light source is fully enclosed and well protected from dust in any environment.



Sealed Engine

Advanced IP6X protection with a sealed engine that eliminates any chance of dust contaminating the projector’s key components.



38,000-hour Long-Lasting Performance
With a fully sealed laser light source and an innovative sealed laser engine design, the LW855UST delivers 38,000 hours of maintenance-free operation under Eco mode, eliminating the need for lamp replacements and maintenance costs.



Ultra Short Throw
The LW855UST ultra short throw laser projector can be mounted just inches from the wall or directly above the screen, eliminating distracting shadows and glare so students and teachers can freely engage and collaborate at the board.



Collaborate Freely on Any Surface
BenQ PointWrite™ technology works on any flat surface, creating new opportunities for classroom interactivity and enabling more possibilities for modern digital classrooms.



Multi-Touch with Pens and Multi-Screen Collaboration

Coupled with PointWrite™ PW30U kit and the PT20 touch module, the LH855UST augments collaboration with styluses or direct touch. In QWrite software Whiteboard Mode, teachers can run different applications r display, view, and annotate across two screens for multiple users at once.

*PointWrite™ PW30U and PT20 are optional accessories sold separately.



Intuitive Setup

BenQ PointWrite™ automatically calibrates and saves its settings the moment it is plugged into a computer’s USB port. Additionally, the LH855UST’s interactive sensor guarantees reliable auto-calibration in any ambient lighting environment.



Control System Compatibility
The LW855UST is widely compatible with leading projector control systems including Crestron, AMX, and PJ Link for network control via LAN, making it simple to integrate into educational network infrastructures. The LW855UST also supports RS-232 for reliable long distance installation of up to 15 meters when there is no LAN port available nearby



Centralized Control with BenQ DMS Software
BenQ DMS Local is a device info and management software suit for Windows. The software helps IT departments control multiple displays at a time via LAN.



Centralized Upgrade Tool for Multi-projector Maintenance
Administrators can centrally upgrade the firmware on multiple networked BenQ 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 for TI IC, MCU IC, LAN IC, and Ballast IC, with a friendly user interface.



Easier BYOD Collaboration
For engaging and intuitive lessons, teachers and students can bring their own smart devices and computers to stream documents, images, and even full HD videos via LW855UST projectors, facilitating open exchange of ideas and collaborative teamwork.

How to use

Install the projector close to the projection surface or mount it according to the ultra-short throw mounting guidelines for your room. Align the unit so the projected image fills the desired area on the wall or board, then adjust focus and keystone or lens shift if available to obtain a rectangular image. Connect source devices such as laptops or media players via the projector’s input connectors and select the appropriate input. Set brightness and color modes according to ambient light conditions to ensure readable text and accurate colours.

Recommendations

For best results in classrooms and meeting rooms, place the projector as close as practical to the projection surface to minimise shadows and presenter glare. Use a matte white projection surface or a dedicated short-throw screen to improve contrast. Regularly clean the lens and maintain ventilation clearance to preserve brightness and image quality.
