Description
Enhance your classroom or AV presentation space with the LH856UST 3500-Lumen Full HD Ultra-Short-Throw Laser DLP Projector from BenQ. Featuring long-lasting laser and DLP technology in an IP6X dust-proof enclosure, the LH856UST will produce bright images with rich color for over 20,000 hours of maintenance-free use. Designed to be installed directly above or below the screen, the ultra short- 0.33:1 throw ratio produces a large image while eliminating distracting shadows and glare, allowing users to engage and collaborate at the board. With wide control system compatibility, the LH856UST can be easily integrated into most networked AV systems via LAN or RS-232. Additionally, you can add wireless screen sharing and whiteboard interactivity with BenQ accessories available separately.
High-Quality Laser Projection
For excellent projection performance, the LH856UST produces 3500 ANSI lumens and Full HD 1920 x 1080 resolution for clear, sharp images and text even in large and bright classrooms. High brightness allows you to keep the lights on during lessons, and wide aspect resolution increases visibility and readability in all types of content.
The LH856UST Interactive Laser Projector produces stunningly clear images with an extra high native contrast ratio of 15,000:1 for true deep blacks, vibrant rich colors, and exquisitely subtle details.
Color Modes to Optimize Performance
With BenQ professional color-grading technology, the LH856UST is tailored for presenting various educational content. Infographic Mode is great for showcasing the text and graphics of infographics in detail, ensuring more saturated and lively color performance than standard Presentation Mode. Vivid Mode is designed for superior color performance for video or image presentations.
Up to 38,000 Hours of Laser Life
With a fully sealed laser light source and an innovative sealed laser engine design, the LH856UST delivers 38,000 hours of maintenance-free operation under Eco mode and 20,000+ hours in standard mode, eliminating the need for lamp replacements and maintenance costs.
IP6X Dust-Proof Sealed Design
An ingenious anti-dust accumulation color wheel sensor repels debris from blocking the IR signal and causing flickering, abnormal colors, or even shutdown. The laser light source is fully enclosed and well protected from dust in any environment. The LH856UST features advanced IP6X protection with a sealed engine that eliminates any chance of dust contaminating the projector’s key components.
Instant Power 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 features instant response, requiring no waiting to turn on or resume for flexible performance.
Control System Compatibility
The LH856UST 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 and corporate network infrastructures. The LH856UST also supports RS-232 for reliable long distance installation of up to 50 feet when there is no LAN port available nearby.
Centralized Control with BenQ DMS Software
BenQ DMS Local is a device info and management software for Windows. The software helps IT departments control multiple displays at a time via LAN. 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 tool can upgrade firmware for TI IC, MCU IC, LAN IC, and Ballast IC, with a friendly user interface.
Optional BenQ PointWrite Interactivity
BenQ PointWrite technology works on any flat surface, creating new opportunities for classroom interactivity and enabling more possibilities for modern digital classrooms. Coupled with PointWrite PW30U kit and the PT20 touch module, the LH856UST 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. BenQ PointWrite automatically calibrates and saves its settings the moment it is plugged into a computer’s USB port. Additionally, the LH856UST’s interactive sensor guarantees reliable auto-calibration in any ambient lighting environment.
PointWrite PW30U and PT20 are optional accessories sold separately.
Optional Wireless Connectivity
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 projector with the QCast Mirror QP30 dongle, 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.
