Vivid image quality with simulation mode
The BenQ LH850ST is specially designed for scenarios that require the highest colour accuracy and visual precision. The unique simulation mode specifically enhances green, yellow and red tones to produce a particularly realistic display. Thanks to the dual colour wheel system with RGBY spectrum, the projector delivers outstanding chromatic performance for lifelike visuals.
Optimal projection in any room
With a short-throw ratio of 0.5, the LH850ST projects crisp images over 100 inches in size from just 1.07 metres away. This prevents distracting shadows or obstacles in the image and ensures an immersive viewing experience – ideal for interactive simulations, indoor entertainment and commercial presentations.
Robust design for demanding environments
The LH850ST's durable construction guarantees reliable 24/7 operation without maintenance. IP5X Dust Guard™ technology effectively protects the optical components from dust and ensures long-lasting performance even in challenging environments. The sealed laser module prevents dust ingress and significantly reduces maintenance costs.
Precise image adjustment and easy installation
The LH850ST offers plenty adjustment options for flexible installation:
- 2D keystone correction for optimal image alignment
- Digital zoom and shift for precise image positioning
- Corner Fit function for individual adjustment of each image corner
- Fast autofocus via remote control for instantly sharp images

Seamless multi-projector setups
The LH850ST enables consistent blending of multiple projectors by minimising differences between projection images using factory white balance settings. This results in seamless, immersive displays without tedious manual calibration.
Wireless connectivity and centralised control
For modern BYOD environments, the projector offers optional wireless projection via a Wi-Fi dongle. This allows up to four participants to present content simultaneously via a shared screen. In addition, the DMS (Device Management System) enables centralised control of multiple projectors, making it easier for IT departments to manage them efficiently across different locations.
Highest image quality with maximum flexibility
With the BenQ LH850ST, you get a high-precision laser projector that impresses with brilliant image quality, flexible installation options and maintenance-free durability. Whether for interactive simulations, professional presentations or immersive experiences, this projector offers a future-proof solution for a wide range of requirements.
