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.

DLP technology for lasting vibrant color

BenQ BlueCore laser projectors are based on the absolute reliability of the 1-chip DLP design. The highly durable DLP chip can last over 100,000 hours without degradation, ensuring true-to-life colors and pristinely legible text over countless uses.

Vivid clarity in bright ambient environments

BenQ BlueCore laser projectors are based on the absolute reliability of the 1-chip DLP design. The highly durable DLP chip can last over 100,000 hours without degradation, ensuring true-to-life colors and pristinely legible text over countless uses.

Laser-powered ultra-high contrast

The LK990 4K laser projector creates strikingly clear images with a stratospherically high 3,000,000:1contrast ratio for true deep blacks, vivid 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.

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 Hour Performance

BenQ BlueCore laser light source is 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 the applications that require powerful color performance and reliable projection quality.

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

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 a 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 the surrounding environment in real-time and automatically adjust the speed of the fans.

High altitude mode for elevated environments

Equipped with an integrated air pressure sensor, LK990’s intelligent High Altitude Mode automatically alerts users to enable efficient cooling and properly maintain operating temperatures in high altitude environments with thinner atmospheres.

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.

Digital Image Shrink

Digital image shrink allows installers to shrink the image to 75% of the original size in 0.5% increments via OSD menu, offering installers an effortless way to precisely align projected images of any size fit well within the desired frame.

Designate remote control ID to a projector for independent control

Installers and IT managers can assign a specific remote control ID to each projector, avoiding signal interference and unintentional changes when installing multiple projectors in a venue.

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.
