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.

Expanding Classroom Possibilities with Collaborative Teaching

• 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 LW855UST augments collaboration with styluses or direct touch. In QWrite software Whiteboard Mode, teachers can run different applications or 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 LW855UST’s interactive sensor guarantees reliable auto-calibration in any ambient lighting environment.

Facilitating Smart and Efficient Projector Maintenance

• 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.
  • * Compatible with the LW855UST and LH856UST, the QCast Mirror QP30 dongle is an optional accessory, sold separately.
