6000 lumens 4K projector for true-to-life images and totally immersive experiences
The world’s No.1 DLP brand, BenQ expands its full line of innovative BlueCore laser projectors for fixed lens installation with LK990, enabling authentic sports matches, enthralling outdoor cinemas, or impactful entertainment in sports bars or private guesthouses.
This projector features:
- 3,000,000:1 contrast ratio
- Support for 360° installation
- 20,000 hours long-lasting performance
Zero-deviation alignment of BlueCore laser diodes boosts luminous flux into the light tunnel, improving light efficacy for superior brightness.
Dual synchronized BlueCore color wheels utilize an additive yellow segment, stimulating precise RGBY spectra for optimal chromatic performance.
Comprising over two million micro-mirrors that reflect pure light through the color wheel, the DLP chip is hermetically sealed to resist heat for over 100,000 hours without degradation, offering superior durability.
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.
- 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.
Hyper-realistic video quality empowered by HDR 10 Technology offers greater brightness, contrast range, and image optimization in a single step, bringing out every detail in 4K content for superior video display.
- Unlike other HDR projectors with oversaturated greens and reds, BenQ Auto HDR Natural Color Rendition technology unleashes breathtaking 4K HDR visuals with perfectly lifelike color performance automatically tuned to reflect nature.
- 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 and Low Maintenance Cost
- BlueCore laser light source is guaranteed for 20,000 hours of superior image quality and maintenance-free operation. BlueCore’s value exceeds that of 10 lamp replacements over the life of the projector.
Sealed laser modules and enclosed light engines protect the DMD chip, color wheel sensor, laser light source, 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 light source and surrounding environment in real-time and automatically adjust the speed of the fans.
High Altitude Mode enables efficient cooling to maintain operating temperatures in high altitude environments with reduced air pressure in thinner atmospheres.
Excellent Installation Flexibility
- 360° rotation and portrait orientation allow projection onto ceiling, walls, floors, or angled signage.
- The 1.47X big zoom offers a wide range of throw distances to significantly increase installation flexibility in challenging venues.
- 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.
- Digital image shrink allows installers to shrink the image to 75% of the original size in 0.5% increments via OSD menu
- Assigning a specific remote control ID to each projector lets you avoid signal interference and unintentional changes when installing multiple projectors in a venue.
Highly Integrated Network Control and Management System Compatibility
- Widely compatible with leading projector control systems including Crestron, AMX and PJ-Link for network control via LAN, making it simple to integrate into corporate network infrastructures. When there is no LAN infrastructure, LK990 also supports RS-232 for reliable long-distance installations up to 15 meters.
- 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 for seamless transmissions up to 100 meters.
