      Laser-Powered Ultra-High Contrast

      LK990 4K laser projector creates strikingly clear images with stratospherically high 3,000,000:1contrast ratio for true deep blacks, vivid rich colors and fine subtle details. LK990 also features a spontaneous response, requiring no wait to turn on or resume from blanking in true black for flexible performance capability.

      DICOM X-ray Imaging

      DICOM (Digital Imaging and Communication in Medicine) is a standard for handling, storing, printing and transmitting medical imaging information. DICOM Simulation Mode is ideal for viewing grayscale medical images, such as X-rays, with an advanced grayscale level for training and educational purposes.

      Enduring Reliability
      Long-Lasting 20,000 Hours Performance

      BenQ laser projectors deliver 20,000 hours of superior image quality and performance. The laser light source resists color decay over time, making BenQ laser projectors ideal for multiple blending projections without concern for adjacent projectors generating different levels of brightness after a period of operation.

      Superior Dustproofing for Severe Conditions

      BenQ's LK990 4K Laser Projector is designed with sealed laser modules and enclosed light engines to protect the DMD chip, color wheel sensor, laser light source, and other optical components. This lock-and-key design hermetically seals the engine from dust* to prolong projector lifespan.
