Resists dust buildup A sophisticated color wheel sensor to protect against dust accumulation prevents foreign objects from blocking the IR signal and causing flickering, abnormal colors or even a shutdown. Sealed laser light source The laser light source is completely encapsulated and well protected from dust in any environment.Sealed engine Advanced IP6X protection with a sealed motor that prevents dust from entering the projector's main components. Instant on and off The LH856UST laser projector can be turned on and off instantly, significantly reducing setup time compared to lamp-based projectors. The LH856UST also offers instant response time, eliminating the need to wait for power on/off and keeping performance flexible. 38,000 hours of sustained performance With a fully sealed laser light source and an innovative sealed laser engine design, the LH856UST provides 38,000 hours of maintenance-free operation in Eco mode, eliminating the need for lamp replacements and maintenance costs. Expanding classroom capabilities through collaborative teaching Ultra short distance The LH856UST ultra-short-throw laser projector can be mounted just a few centimeters from the wall or directly above the screen, eliminating annoying shadows and glare and allowing students and teachers to work unhindered at the board.Free collaboration through interactivity BenQ PointWrite™ technology works on any flat surface, creating new possibilities for classroom interactivity and opening up more possibilities for modern digital classrooms. Multi-touch with pens and multi-screen collaboration When paired with the PointWrite™ PW30U kit and PT20 touch module, the LH856UST improves pen or direct touch collaboration. QWrite software's Whiteboard mode allows teachers to run multiple applications or display, view, and annotate on two screens for multiple users at the same time. Intuitive setup BenQ PointWrite™ automatically calibrates and saves its settings when connected to a computer's USB port. In addition, the LH856UST's interactive sensor guarantees reliable automatic calibration in any ambient lighting condition.

Simplified 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 the LH856UST projectors, facilitating open exchange of ideas and team collaboration . Smart device management Compatibility of control systems The LH856UST is widely compatible with leading projector control systems such as Crestron, AMX and PJ Link for network control over LAN, enabling easy integration into educational network infrastructures. The LH856UST also supports RS-232 for reliable installation over long distances of up to 15 meters when a LAN port is not available nearby. Centralized control with BenQ DMS software BenQ DMS Local is a device information and management software for Windows. The software helps IT departments control multiple screens simultaneously via LAN. Centralized upgrade tool for multiple projector maintenance Administrators can centrally update firmware for multiple networked BenQ projectors on the same local network over LAN (up to 253 projectors) and distribute the latest updates to all devices simultaneously. This new tool can update firmware for TI IC, MCU IC, LAN IC and Ballast IC with a user-friendly interface. Perfect image alignment and easy installation Optimized alignment of the wall mount For efficient and professional installation, the LH856UST ultra-short throw wall mount is equipped with an installation table and ruler, allowing perfect alignment of the projection screen and image positioning in the classroom. To make installation even easier, there is a three-way adjustment knob on the front of the projector.Clear images without distortion 2x digital zoom The 2x digital zoom offers a wide range of projection ratios, increasing installation flexibility for various mounting and placement options. Resize and move digitally Zoom out and move the projection via the OSD without having to reinstall or physically adjust the projector. 2D Keystone & Corner Fit The LH856UST is equipped with two-dimensional keystone correction. Corner correction adjusts every corner for perfectly aligned image geometry.Lasting image perfection from the world's leading DLP brand Better readability BenQ education projectors feature industry-leading high contrast and utilize advanced DLP-optimized optical lens systems to ensure precise readability and sharp resolution for every single subpixel. Long-lasting image quality With durable, industrial-grade DLP technology, BenQ education projectors ensure long-lasting image perfection without color degradation. Unlike non-DLP projectors, BenQ's DLP education projectors deliver picture quality that is like new over a long lifespan. With over two million micromirrors and minimal heat generation, the DLP chip used by BenQ lasts more than 100,000 hours without loss of quality.
