BenQ LK830ST

The BenQ LK830ST is a dedicated short throw laser projector designed for professional and commercial environments where a large image is needed from a relatively short projection distance. Featuring 4K UHD resolution (3840 x 2160 pixels via upscaling technology) and a 0.5:1 lens, its compact installation footprint makes it suitable for museums, retail displays, visitor attractions, classrooms, meeting rooms and simulation spaces. The laser light source offers long operating life with reduced maintenance requirements, while the sealed optical engine helps maintain consistent image performance over extended use.

For flexible installation, the LK830ST supports portrait projection, 360-degree orientation and a range of image adjustment features, allowing it to be used on walls, floors and other creative surfaces. Comprehensive connectivity options make integration with existing AV systems straightforward, and its low-latency performance is well suited to interactive applications and immersive visual experiences where responsive image delivery is important.

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) reduces 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

Up to 300-Inch Display
0.5 short throw ratio for large image from a short distance in limited spaces.

Ready for Dusty Venues

1 – 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.

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

3 – 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.
