## Long description

The BenQ LH850ST is a short-throw DLP laser projector that delivers 4,000 ANSI lumens brightness and native Full HD (1920x1080) resolution. Designed for installation in confined spaces, the LH850ST uses a 0.5 throw ratio to project large images from short distances, offers a long-lasting laser light source, and includes sealed optical components for improved durability and dust resistance.
Advantages
The LH850ST combines DLP imaging with dual color wheels (RGBY) and a dedicated Simulation Mode to enhance color accuracy and visual clarity, especially for greens, yellows and reds. Its laser engine provides stable color over time and a long service life, while IP5X dust-sealing protects internal optics for reliable 24/7 operation. The projector supports fast start-up, edge blending with factory white-balance calibration, precise image adjustment (digital reduction, shift and 2D keystone), and optional wireless presentation via a Wi‑Fi dongle.
Suitable for
Short-throw installations in small rooms and classrooms
Interactive displays, simulation and training environments
Commercial exhibitions and signage
Meeting rooms requiring multiple-projector edge blending

How to use
Place the LH850ST at the appropriate short-throw distance from the screen according to the desired image size (for example, over 100 inches from approximately 1.07 m). Connect video sources via HDMI, control systems via RS-232 or Ethernet, and attach the optional Wi‑Fi dongle for wireless mirroring. Use the remote control or onboard menus to perform digital reduction and shift, 2D keystone correction and fine angle adjustment to position the image precisely. For multi-projector setups, use the factory white-balance and edge-blending functions to achieve uniform output across screens.
Usage recommendations
Install the projector in a location that allows the short-throw lens to be aimed without obstruction to avoid shadows; maintain the sealed optical path and follow routine cleaning and DMS (Device Management Solution) monitoring for best long-term performance.
