Revolutionary Laser Technology
Revolutionary Laser Technology BenQ extends its full line of revolutionary laser projectors featuring unique DLP high-brightness laser technology with LK954ST, a short-throw fixed-lens projector built for easy and flexible installation in tight spaces.

Superior Brightness

Superior Brightness Zero-deviation alignment of laser diodes boosts luminous flux into the light tunnel, enhancing light efficacy to 5,100 lumens.

Designed with IP5X Protection

Designed with sealed laser modules and enclosed light engines that protect the DMD chip, colour wheel sensor, laser package, and other optical components to prolong the projector’s lifespan.

Superior Durability

Comprising over two million micromirrors that reflect pure light through the colour wheel, the DLP chip is hermetically sealed to resist heat for over 20,000 hours without degradation.

24/7 Operations
BenQ laser projectors support 24/7 operation and are suitable for public display applications in museums and exhibitions. Users can choose from three different light-source modes to optimize energy consumption and deliver up to 70,000 continuous hours in Dimming Mode.

Optimize Image Quality with 4K Upscaling
LK954ST produces 4K UHD 3840 x 2160 resolution with 8.3 million distinct pixels. To ensure the best image quality, LK954ST adopts cutting-edge 4K Image Upscaling technology off all projected images to a resolution of 4K automatically, which guarantees superb image sharpness and details.

< 17ms Latency for Hyper-Responsive Simulation
System latency, which is the lag time between when an operator applies an input and when the simulator responds with visual and motion cues, is inevitable in simulators. Based on expertise gained from BenQ experience with near-zero latency gaming, LK954ST employs a Fast Mode to provide latency as low as 16.67ms*(@4K 60Hz).
