Brilliant Visuals with Stable Colour and Performance
The LK830ST delivers brilliant image clarity and stable performance across every detail—from vivid Rec.709 colour and high contrast to 4000-lumen brightness (ANSI) and 20,000-hour laser life.

BenQ WBA for Seamless Multi-Projector White Calibration
BenQ’s factory white balance adjustment (WBA) reduce variables between images projected from different projectors, significantly reducing manual calibration effort. It can save up to a full day of setup time in large-scale installations while ensuring seamless multi-projector alignment for edge blending.

Full flexibility for ceilings, walls and floors

360° and Portrait Projection for Full Installation Freedom

Ready for Dusty Venues

IP6X Sealed Engine Design for Dust-Prone Environments
Shields the projector’s optical engine from dust intrusion, ensuring long-term stability and reliable performance in harsh, dust-prone environments such as exhibition halls, factory spaces, and training centers.

Optional Filter for Extra Protection
Provides added protection in dusty environments and helps extend projector life.

Auto Reset Mechanism with Built-in Timer
Automatically tracks filter usage and resets the timer when a new filter is installed, without any manual setup.

IT Takes Control

Streamlined Device Management

Remote Monitoring and Diagnostics
Easily track projector status and diagnose issues remotely, eliminating frequent on-site visits.


Firmware Management Over Network
Easily update all projectors via LAN to keep firmware current without physical access.


Reliable Performance, Less Maintenance
Ensure long-term stability, freeing SI teams to focus on creative installations rather than routine upkeep.
