LK970 main features

Key Features:

  • 4K BlueCore Laser Technology
  • Long Lasting, Supreme Image Quality
  • Enduring Reliability
  • Excellent Installation Flexibility

(See Features tab for details.)


Long Lasting, Supreme Image Quality

  • 4K UHD (3840 x 2160) resolution with 8.3 million distinct pixels for each frame delivers awe-inspiring clarity and crisply defined fine details. 
  • Finely crafted optical lens for high-resolution image clarity without distortion, ideal for entertainment simulators and gallery exhibitions.
  • High-precision 16-element 8-group lens array guarantees long-lasting 4K intensity, breathtaking clarity, sharpness, and color performance across the entire screen. The 16 low dispersion lenses minimize chromatic aberration. 
  • Superb image detail and color integrity from DMD DLP Technology. Problems such as blurriness, shadowing, and interference patterns are eliminated.
  • Dual color wheels increase color ratios and purity of RGBY color, dramatically enhancing color saturation.
  • Highly durable DLP chip can last over 100,000 hours without degradation ensuring lasting vibrant colors.
  • Cutting-edge 4K Image Amplifying Technology and Pixel Enhancer 4K further enhance the quality of projected images.>
  • Ultra-high 3,000,000:1 contrast ratio ensures true deep blacks, vivid rich colors and fine subtle details.
  • DICOM Simulation Mode is ideal for viewing grayscale medical images, such as X-rays.

Enduring Reliability

  • BlueCore laser light source is guaranteed for 20,000 hours of superior image quality and performance.
  • Supports continuous 24/7 operation with three different light source modes to optimize energy use and extend the projector’s life up to 60,000 hours in Eco Mode.
  • Sealed laser modules and enclosed light engines protect the DMD chip, color wheel sensor, laser bank, and other optical components from dust to prolong projector lifespan.
  • Two advanced cooling systems ensure optimal thermal conduction during operation in ambient temperatures up to 40°C (104°F). In addition, thermal sensors detect the temperature of the laser-bank and surrounding environment in real-time and automatically adjust the speed of the fans.

Excellent Installation Flexibility

  • 360° rotation and portrait orientation allow projection onto ceiling, walls, floors, or angled signage.
  • High Altitude Mode enables efficient cooling to maintain operating temperatures in high altitude environments with reduced air pressure in thinner atmospheres.
  • The 1.47X big zoom offers a wide range of throw distances to significantly increase installation flexibility.
  • Horizontal and vertical lens shift can move projected images up and down by 60% of screen height, or left and right by 25% of screen width without sacrificing image quality.

Centralized Management and Diverse Application

  • Requires no wait to turn on, or resume from blanking in true black.
  • Consistent brightness blending across multiple projections with Custom Light Mode.
  • Compatible with Creston, AMX, and Extron control systems for convenient system integration with various third-party components.
  • Multiple Display Administrator (MDA) software provides powerful centralized multi-projector management.
  • HDBaseT connectivity combines video, audio and device control signals from multiple sources (including PCs, laptops, document cameras, Blu-rays and DVDs) onto a single CAT5 cable for seamless transmissions up to 100 meters.
  • In Standby Mode, power consumption is a minuscule 0.5 watts.
