Laser-Enabled Ultra-High Contrast
LK990 4K Laser Projector creates strikingly clear images with stratospherically high native contrast ratio of 100,000:1 for true deep blacks, vividly rich colors, and fine subtle details. LK990 also features spontaneous response, requiring no wait to turn on or resume from blanking in true black for flexible performance capability.
20,000 Hour Long-Lasting Performance
BenQ BlueCore laser projectors are guaranteed for 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.
BenQ laser projectors support continuous 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 use and extend the projector’s life up to 60,000 hours in Eco Mode.
Superior Dustproofing for Severe Conditions
BenQ LK990 4K Laser Projector is designed with sealed laser modules and enclosed light engines to protect the DMD chip, color wheel sensor, laser bank, and other optical components. This lock-and-key design hermetically seals the engine from dust* to prolong projector lifespan.
*Dust chamber test standard: JIS Class IP6X
Groundbreaking Thermal Conduction through Innovative Cooling Systems
LK990 employs two advanced cooling systems to ensure optimal thermal conduction during operation. The circulatory liquid cooling system protects the laser light bank and DLP engine even after constant operation in ambient temperatures up to 40°C (104°F), while the heat pipe cooling system cools the DMD chip to effectively produce a comfortable sound with improved reliability.
Additionally, LK990 also comes with several embedded thermal sensors to intuitively control the projector's temperature and ensure optimal operation. The sensors can detect the temperature of the laser-bank and surrounding environment in real-time and automatically adjust the speed of the fans.
