Ever wondered why speakers, amplifiers, projectors etc. come with a slightly heftier price tag in India compared to their overseas counterparts? Well, part of the answer lies in our country's Goods & Services Tax (GST).
But here's the kicker: Don't let that GST input slip through your fingers! Especially when some of the products we supply carry a GST rate of 18% and 28%.
At AVStore, we provide you with a GST compliant invoice for every purchase.

With wide control system compatibility, the LW855UST 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 LW855UST produces 3500 ANSI lumens and WXGA 1280 x 800 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 LW855UST Interactive Laser Projector produces stunningly clear images with an extra high native contrast ratio of 16,000:1 for true deep blacks, vibrant rich colors, and exquisitely subtle details.
Color Modes to Optimize Performance
With BenQ professional color-grading technology, the LW855UST 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 LW855UST 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 LW855UST 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 LW855UST laser projector can be turned on and off instantly, significantly reducing setup time compared to lamp-based projectors. The LW855UST also features instant response, requiring no waiting to turn on or resume for flexible performance.
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 and corporate network infrastructures. The LW855UST 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 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. 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. 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 LW855UST projector with the QCast Mirror QP30 dongle, facilitating open exchange of ideas and collaborative teamwork.
