This projector is a game changer! It's advertised as an installation projector, but it's much more than this. It is absolutely suitable for larger screens, over say 130, 140 inch in size. And suitable for our Evo Ultra Grey 4K material which can be made out to 2.2 metres high (2.4 spool) viewing area, which is about 178-180 inches in size.

Instant start up, no warming up and waiting, no convergence problems, no chromatic aberrations, no focus drift so no having to check your projector each time. None of the problems that plague 3 chip projectors. This projector can run 24/7 if need be.

 

Precisely visualizing 8.3 million distinct pixels, BenQ LK990 4K Laser Projector brings together true 4K UHD detail and the power of maintenance-free BlueCore laser light source. Ideal for home cinemas, entertainment simulators and gallery exhibitions, LK990 generates supreme picture quality to reproduce true-to-life images for totally immersive experiences for audiences. Offering up to 20,000 hours of perfect performance, LK990’s flexible installation features such as H/V lens shift, big zoom, 360° projection and portrait capability make it a versatile projector perfect for diverse venues.

 

BlueCore Laser Technology - Harness The Power of Lasers

The BlueCore laser source uses dual color wheels to significantly improve white balance and overall brightness. In addition to strikingly clear, bright whites, this projector’s pure RGBY colors are achieved by eliminating the white segment of a conventional color wheel, so it produces an ideal mixture of red, green, blue and yellow color segments on its own. Through this optimization of RGBY colors, this premium laser projector runs the gamut of precise color ranges.


Long Lasting, Supreme Image Quality
4K UHD Image Quality for Perfect Pictures with Subtle Details. Harnessing the advanced DLP 4K UHD DMD with 2716 x 1528 (4.15 million) micromirrors, LK970 achieves Consumer Technology Association’s (CTA) 4K UHD specification via XPR fast-switching technology. Utilizing a dual-position precision optical actuator with state-of-the-art image processing, LK970 doubles the resolution to 8.3 million distinct pixels for each frame, four times the resolution of Full HD 1080p. The awe-inspiring 4K UHD image quality reduces blur between pixels to deliver supreme clarity and crisply defined details.

 


Finely-Craft Optical Lens for High-Resolution Image Clarity
LK990’s high-performance lens system employs sophisticated optical design to deliver true-to-life images with a high differential rate reflected through the 5.4 micrometer image resolution produced by the DMD. This innovative optical lens eliminates image distortion, achieving the best possible image clarity suitable for entertainment simulators and gallery exhibitions.

 

High-Precision 16-Element 8-Group Lens Array Guarantees Stable Image Quality
LK990’s 4K-optimized lens system consists of a super-high resolution 16-element lens array structured into 8 groups. The lenses are made from the highest-grade all-glass substrates, with metal barrel and cell framework. The lens system comes with greater light penetration that guarantees long-lasting 4K intensity, breathtaking clarity, sharpness, and color performance across the entire screen.


Flawless Optics for the Best Color Performance and Picture Quality
LK990’s 16 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. The result is superbly delicate image quality that guarantees the best viewing experience.


Superb Image Detail and Color Integrity from DLP Technology
To avoid inherent alignment issues of multiple panels, BenQ LK990 4K Laser Projector preserves color and image integrity with 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 Wheels 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, dramatically enhancing color saturation to ensure superior viewing experiences.


Laser-Enabled 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.


Enduring Reliability
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.

 

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 bank, and other optical components. This lock-and-key design hermetically seals the engine from dust to prolong projector lifespan.

 

Innovative Cooling Systems

 

The LK990 employs two advanced cooling systems to ensure optimal thermal conduction during operation. Its 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.

 


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.


Synchronized True Zoom and Focus System for Ultimate Precision
LK990‘s True Zoom system adjusts automatically to follow focus adjustments, optimizing the zoom ratio to deliver visually perfect focus without blemish. The focusing lens groups adjust simultaneously with the zoom lens group to negate any curved field for immaculate cinematic performance and high-precision clarity at every corner of the image.
