Installer Ready

Optimised for Multi-Projector Projects from Fast Setup to Long Term Performance

Blending Ready Mode
One-click preset for multi-projector blending to minimise setup effort

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
