BlueCore Laser Technology
Revolutionary BlueCore Laser Technology
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.
Long Lasting, Supreme Image Quality
4K UHD Image Quality for Flawless Presentation with Subtle Details
LK990 utilizes the DLP 4K UHD's 4.15 million micromirrors and the fast switching speed as well as the advanced image processing capability to achieve Customer Technology Association's (CTA) 4K UHD specification, delivering a 3840 x 2160 resolution with 8.3 million distinct pixels for each frame. With a resolution that's 4 times higher than Full HD 1080p, 4K UHD reduces pixel blur for awe-inspiring clarity and crisply defined fine details.
Superb Image Details and Color Integrity from DLP Technology
To avoid inherent alignment issues of multiple panels , which can be more serious when projecting 4K content, BenQ LK990 4K Laser Projector preserves color and image integrity with the single DMD DLP technology. Generating razor-sharp images and pure colors, LK990 eliminates problems such as blurriness, shadowing, and interference patterns for immaculate clarity.
Dual Color Wheel for Optimal Color Performance
LK990’s powerful BlueCore laser projection utilizes a dual color wheel system to produce unparalleled color performance by increasing color ratios and purity of RGBY color while achieving 92% of Rec.709 color coverage, dramatically enhancing color saturation to ensure superior viewing experiences.
Hyper-Realistic Video Quality Empowered by HDR 10 Technology
Supercharged by HDR10 support with BenQ’s exclusive Auto HDR Color Rendition, LK990 high Dynamic Range performance offers greater brightness, contrast range, and image optimization in a single step, bringing out every detail in 4K content for superior video display.
Auto HDR Natural Color Rendition for Lifelike Color Realism
Unlike other HDR projectors with biased color temperature and 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.
Optimize Image Quality with 4K Image Amplifying Technology
To ensure the best image quality, BenQ LK990 adopts the cutting-edge 4K Image Amplifying Technology to further enhance the quality of projected images. LK990 automatically upgrades the resolution of all projected images to 4K, guaranteeing superb image details. Additionally, LK990 also comes with Pixel Enhancer 4K, a motion-adaptive edge enhancement feature that detects changes in the color between an object and its background to produce sharp edges and precise surface textures.
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.
Long-Lasting 20,000 Hours Performance
BenQ BlueCore 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.
*Dust chamber test standard: IEC Standard 60529IP6X
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 source 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 light source and surrounding environment in real-time and automatically adjust the speed of the fans.
Excellent Installation Flexibility
360° and Portrait Projection Accommodate Diverse Spaces
BlueCore laser technology guarantees reliable projection from any angle. Dynamic installation options such as 360° rotation and portrait orientation allow projection onto ceiling, walls, floors, or angled signage.
Big Zoom and Lens Shift for Flexible Installation
LK990’s wide zoom range, focus, and horizontal/vertical lens shift systems can perfectly align images in any challenging venue. 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. The 1.47X big zoom feature offers a wide range of throw distances to significantly increase installation flexibility for diverse mounting options in various public display scenarios.
Low Maintenance Cost
Laser Light Creates Value Over Time
BenQ BlueCore projectors feature laser light sources that are guaranteed for 20,000 hours of maintenance-free operation, saving costs for lamp replacement and maintenance. Based on the average brightness cut-off of typical long-life lamps, BlueCore’s value exceeds that of 10 lamp replacements over the life of the projector.
