With exceptional color accuracy, brightness, and installation flexibility, the LK936ST 5100-Lumen 4K UHD Short-Throw Laser DLP Projector from BenQ can be the centerpiece of everything from your home theater, a retail or art installation, and even a virtual golf range. A 0.47" single-DMD DLP system works with 5100 lumens of laser light to deliver stunning 4K resolution and 92% of Rec.709 for cinematic-grade color accuracy. Thanks to the short 0.81 to 0.89:1 throw, these detailed images can project up to 10' tall from just 14-15' away. A variety of adjustments let you project to almost any wall, ceiling, or floor, and HDBaseT network connectivity makes remote management fast and easy.

Installation & Adjustment Flexibility
The LK936ST is at home in almost any space, with 360° installation support and the ability to project in portrait orientation for vertical applications. Even if an off-center installation is required, up to 60% vertical and 23% horizontal lens shift can get your image where it needs to be.

After it's installed, 3D keystone correction and Corner Fit lets you fix any trapezoidal images with ±40% vertical and horizontal correction and rotation either clockwise or counterclockwise. The image can even be shrunk to 75% of the original size in 0.5% increments without distortion, then shifted into place using the OSD menu. This kind of control and freedom allows for projection on not just walls and screens, but also angled walls, ceilings, and floors if needed.

Superior Imaging
Whether it's art in a gallery, ads in a lobby, or movies and games at home, the LK936ST can make everything look clean and accurate thanks to the technologies used by the laser light source and DLP system.

  • Brightness: Zero-deviation alignment of laser diodes improves the projector's light efficacy
  • Performance: Dual synchronized color wheels use an additive yellow segment, stimulating precise RGBY spectra for optimal chromatic performance and color saturation.
  • Durability: Over 2 million micromirrors reflect pure light through the color wheel, and a hermetically sealed DLP chip resists heat for over 20,000 hours of operation.
4K Image Upscaling Technology
To ensure the best image quality, LK936ST uses 4K Image Upscaling Technology to further enhance the quality of projected images. LK936ST automatically upgrades the resolution of all projected images to 4K, enhancing image details no matter the source resolution.
Golf Mode
BenQ worked with color experts and used examples from popular golf software to create Golf Mode, which is able to reproduce the lush greens and vivid blue skies of your favorite course. A quick setting option, Golf Mode corrects purple fringing using the blue and green colors from popular golf software and allows golfers to immerse themselves in pleasantly natural reproductions of blue sky and green grass.
Low Maintenance
Thanks to a hermetically sealed DLP chip, filter-free IP5X dust proofing, sealed laser modules, and enclosed light engines, dust is minimized to extend image quality and reduce maintenance costs over time.
DMS Local
DMS Local is management software for Windows OS that lets you remotely control multiple projectors over LAN or through the cloud using Agent Mode.
