BlueCore Laser technology


Superior Image Quality

  • Dual color wheels produce 95% Rec.709 color coverage for optimal color performance including enhanced color saturation.
  • High-precision 12-element lens structured into 4 groups guarantees long-lasting full HD intensity, crystal clear clarity, sharpness and color performance.
  • Low dispersion lenses minimize chromatic aberration via a customized optical parameter and ultra-low reflective coating that prevent shape distortion while safeguarding perfect projection quality.
  • Infographic Mode masters infographic-heavy presentations, showcasing the text and graphics in detail and ensuring more saturated and lively color performance than presentation mode. Additionally, Vivid Mode is designed for supreme color performance during video or image presentation.
  • High brightness provides vivid clarity in comfortably lit medium-sized conference rooms.

    Ultra-high 3,000,000:1 contrast ratio ensures true deep blacks, vivid rich colors and fine subtle details.

Enduring Reliability

  • BlueCore laser light source delivers 20,000 hours of superior image quality and performance, exceeding that of 10 lamp replacements over the life of the projector.
  • Powers up in half the time of a lamp-based projector, reducing wait time and power consumption.
  • Highly durable DLP chip can last over 100,000 hours without degradation ensuring true-to-life colors and pristinely legible text over countless uses.
  • Sealed laser modules and enclosed light engines protect the DMD chip, color wheel sensor, laser bank, and other optical components. (Has passed the dust chamber test standard JIS Class IP5X.)

Versatile Wireless Presentation Solutions

  • One button to start Full HD wireless presentations (from up to 16 presenters) with InstaShowTM WDC10 plug-and-play device (available separately).
  • QCast Wi-Fi dongle (available separately) lets up to four presenters wirelessly project Full HD multimedia content, including videos, documents, and live camera (video) sessions from any mobile device, in four split screens.

Excellent Installation Flexibility

  • 360o Rotation Projection allows projection onto ceilings, walls, floors, or angled signage.
  • 1.5X big zoom allows LX770 to be mounted anywhere from 4.4 to 6.8 meters from the screen and project images of 120", which is the typical image size for corporate meeting rooms.
  • Symmetrically centered lens design allows easy installation without the need for special calculations.
  • Horizontal and vertical lens deliver perfectly proportioned images despite installation or placement challenges in any venue.
  • 2D keystone correction range of ±30on both horizontal and vertical axes counteract the trapezoid effect, while Corner Fit control lets you adjust each corner to provide ideal projection alignment.

Highly Integrated Network Control and Management System Compatibility

  • Compatible with leading projector control systems, including Extron, Crestron, 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.
