## Long description

The BenQ LH830ST is a short-throw DLP projector with native UHD 4K (3840x2160) resolution and 4000 ANSI lumens brightness. Designed for installations that require clear, detailed images from a short distance, it uses a laser light source rated for up to 20,000 hours of service life and supports fixed zoom with a short-throw ratio for large images in confined spaces. The projector includes network connectivity and management features suitable for multi-projector systems and professional AV deployments.
Advantages
The LH830ST delivers stable colour performance and high visual clarity including Rec.709 accuracy, a high contrast ratio and 4000 ANSI lumen brightness for reliable visibility in well-lit environments. It offers an installer-ready workflow with a one-click blending preset to reduce setup time for multi-projector arrays and BenQ WBA factory white-balance calibration to minimise manual adjustments. The optical engine is sealed to IP6X standards for dust resistance, and an optional protective filter plus an automatic filter-timer reset mechanism help reduce maintenance. Network-based firmware management and remote monitoring simplify large-scale deployment and ongoing diagnostics.
Suitable for
 Multi-projector edge-blending installations in auditoriums and exhibition halls
 Meeting rooms and classrooms requiring short-throw projection
 Permanent installations in dusty or industrial spaces
 AV systems that require centralized firmware updates and remote diagnostics

How to use
Install the LH830ST on a short-throw mount or surface so the projector is positioned at the recommended distance for the desired image size. Use the one-click blending preset for multi-projector setups and activate BenQ WBA factory calibration to harmonize colours across units. Connect to the local network to enable remote monitoring, firmware updates and diagnostics. If installed in dust-prone environments, fit the optional protective filter and allow the projector’s auto reset mechanism to track filter usage when replacements are fitted. Refer to the official installation guide for exact throw-distance tables, mounting orientations (including 360° and portrait projection), and safety instructions.
Usage recommendations
For multi-projector edge blending, perform initial alignment and white-balance using the BenQ WBA and the one-click blending preset, then fine-tune geometry and overlap. In dusty venues, use the optional filter and schedule periodic checks; rely on network firmware management to keep all projectors updated without individual onsite maintenance.
