Description
The BenQ LK936ST is a high-brightness 4K UHD laser projector engineered for immersive large-format visuals in professional environments. Delivering 5100 ANSI lumens and a 3,000,000:1 contrast ratio, it produces vivid detail, deep blacks, and accurate color performance for conference rooms, simulation spaces, museums, and high-impact installations.
Its short throw ratio of 0.81 to 0.89 enables large 4K images in tight spaces, while manual lens shift and 1.1x zoom provide flexible installation. Advanced features such as 3D keystone correction, digital shrink and shift, 4K upscaling, and 360 degree projection ensure precise alignment and creative deployment options.
With a long-lasting laser light source rated up to 20,000 hours in Normal mode and 30,000 hours in Eco mode, the LK936ST offers reliable, low-maintenance operation. Connectivity options including dual HDMI with HDCP 2.2, HDBaseT, DisplayPort, LAN control, and S/PDIF make it integration-ready for modern AV systems.
