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

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.
