Description

BenQ LK830ST is a professional 4K UHD short-throw laser projector designed for environments that require high detail, strong brightness, and flexible installation. With 4000 ANSI lumens, a laser light source, and 3,000,000:1 dynamic contrast, it delivers bright and clear images even in rooms with moderate ambient light.

The short-throw optics with a throw ratio of around 0.5 allow projection of a large image from a very short distance—an ideal solution for driving and flight simulators, training centers, interactive installations, projection mapping (house-mapping), and spaces where the projector must be positioned close to the screen or object.

The projector supports HDR10, 93% Rec.709 color coverage, and 30-bit color depth, ensuring realistic colors and high accuracy for visualization, training, and demonstrations. Installation flexibility is exceptional, with 360° positioning, portrait mode, 2D keystone, corner fit, screen fill, and edge blending for multi-projector configurations.

Thanks to its IP6X sealed optical engine, the LK830ST is highly resistant to dust and suitable for demanding environments such as showrooms, museums, training halls, themed attractions, and industrial applications. Support for LAN control, RS-232, and a 12V trigger makes integration into professional AV systems straightforward and efficient.
