Description
The BenQ LH850ST is a powerful short throw laser projector engineered for immersive simulation, training, and commercial display environments. Delivering 4000 ANSI lumens of brightness and Full HD 1920 × 1080 resolution, it produces sharp, vibrant images even in well-lit spaces.
With a 0.499 short throw ratio, the LH850ST projects large 16:9 images from close distances, making it ideal for golf simulators, retail displays, training rooms, and compact spaces. The laser light source provides up to 20,000 hours (Normal) and 30,000 hours (Eco) of maintenance-free operation, ensuring long-term reliability and lower total cost of ownership.
Advanced installation tools such as motorized focus, 2D keystone correction (±30° vertical and horizontal), Corner Fit, and the Screen Fill hot key simplify setup and alignment. The IP5X sealed engine enhances durability by protecting internal components from dust, while factory white balance adjustment ensures accurate and consistent color performance.
With dual HDMI 2.0 inputs, LAN control, RS232, built-in 10W speaker, and optional Wi-Fi capability, the LH850ST integrates seamlessly into professional AV environments.
