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 details. 
  • Revolutionary 0.47” single-DMD DLP technology preserves color and image integrity while maximizing the projector’s sleek, compact profile.
  • Cutting-edge 4K Image Amplifying Technology and Pixel Enhancer 4K further enhance the quality of projected images.
  • High Dynamic Range performance, supercharged by HDR10 support with BenQ’s exclusive Auto HDR Color Rendition, offers greater brightness, contrast range, and image optimization.
  • Highly durable DLP chip can last over 100,000 hours without degradation ensuring lasting vibrant colors and pristinely legible text.
  • 5000 lumens high brightness produces wondrous displays in bright, compact exhibition spaces with superb image quality.
  • Ultra-high 3,000,000:1 contrast ratio ensures true deep blacks, vivid rich colors and fine subtle details.
  • Perfect digital HDMI output allows multi-projector/multi-screen setups with no signal degradation.
  • DICOM Simulation Mode is ideal for viewing grayscale medical images, such as X-rays.

Excellent Installation Flexibility

  • 0.8 short-throw ratio produces larger-than-life images in tight spaces, and lets viewers move freely in front of the screen without distracting shadows and glare.
  • 360o Rotation Projection allows projection onto ceilings, walls, floors, or angled signage.
  • 1.1X 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 23% of screen width.
  • Wired Remote Control offers projector installers and IT managers extra setup convenience. 
  • Bottom surface grips and center-of-gravity mark facilitate safe transport and installation.

Enduring Reliability

  • Sealed laser modules and enclosed light engines protect the DMD chip, color wheel sensor, laser light source, and other optical components. (Given international dust-proof rating of IP5X.)
  • Anti-dust buildup feature in the color wheel sensor prolongs optimal performance.
  • BlueCore laser light source is guaranteed for 20,000 hours of superior image quality and performance, exceeding that of 10 lamp replacements over the life of the projector.
  • Integrated air pressure sensor alerts users to enable efficient cooling and properly maintain operating temperatures in high altitude environments with thinner atmospheres.

Highly Integrated Network Control and Management System Compatibility

  • Compatible with leading projector control systems, including Extron, Crestron, AMX and PJ-Link for network control via LAN.
  • RS-232 support for reliable long-distance installations up to 15 meters, when LAN infrastructure doesn't exist.
  • 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, and Blu-rays) onto a single CAT5 cable, ensuring seamless transmissions up to 100 meters.
