• BenQ LK954ST 4K Short-Throw Installation Projector – 5100 Lumens

  DLP Technology for Long-Lasting Vibrant Colour
  BenQ laser projectors run on Academy Award-winning DLP technology to deliver true-to-life colors across the projector’s long lifetime.

  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.

  Superb Image Quality for Effective Immersion
  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).

  92% Rec.709 Colour Coverage for Optimal Colour Performance
  LK954ST’s powerful laser projection utilizes a dual colour wheel system to produce unparalleled colour performance that achieves 92% Rec.709 colour coverage. By increasing colour ratios and the purity of RGBY colour, LK954ST dramatically enhances colour saturation to ensure superior presentation quality.

  Gamma Selection
  Select Gamma for your preference and optimizing image quality between input source and picture brightness. Besides, LK954ST also provides advanced BenQ and DICOM Gamma curve to satisfy your various needs.

  Flexible Installation in a Compact Fixed-Lens Projector

  
  Short-Throw Design
  Fill up a 12-foot-wide screen from less than 10 feet away without casting a shadow.

  360° and Portrait Projection
  Allow projection onto ceilings, walls, floors or angled signage from any angle.

  Zoom Lens and Lens Shift for mounting flexibility
  LK954ST features both a 1.1X zoom function and vertical/horizontal lens shift, enabling a fully-aligned image on your screen while moving the image up or down to 60% of the screen height, while adjusting the horizontal position by 23% for an off-axis mounting location. The zoom lens can also enlarge or reduce the image, enabling you to move the mounting position as much as a foot on a 12-foot-wide screen.

  2D Keystone and Corner Fit for Ideal Projection Alignment
  To counteract the trapezoid effect that can occur when a projector is installed off-centre, BenQ LK954ST offers a two-dimensional keystone correction range up to ±40° on both the horizontal and vertical axes. Corner Fit control can adjust each corner, respectively, for perfectly aligned image geometry.

  White Balance Calibration for Seamless Edge Blending
  BenQ exclusive out-of-the-box white balance consistency makes images projected from different projectors so consistent that most people cannot see any difference between them, making for seamless and accurate picture quality without distracting discrepancies.

  One-click Professional Simulator Settings
  One-click Professional Simulator Settings LK954ST is equipped with Simulator Mode, allowing users to activate an array of pre-calibrated settings optimized for high-accuracy professional training with the touch of a button.

  *Notice: Turn on Simulator Mode to activate a predefined setup profile. You can recover your settings by turning off Simulator Mode.

  
  High Resolution and Accurate Colour Transmission
  HDMI 2.0
  HDMI 2.0 cable can handle 18Gbps bandwidth, allowing for 4K 60Hz plus HDR metadata at low latency and faster refresh rates.

  DisplayPort
  DisplayPort 1.2a enables simultaneous high-bandwidth audio and video transmission. In addition, the dual barbs on the connector provide a friction lock, and an option for a mechanical latch.

  S/PDIF
  S/PDIF is capable of supporting 5.1-channel surround sound output.

  HDBaseT
  HDBaseT connectivity combines Video, Audio, RS-232 and LAN signal control signals from multiple sources into a single RJ-45 cable, ensuring seamless transmission from up to 100 meters away.
