Generating razor-sharp images and pure colours, LK953ST eliminates problems such as blurriness, shadowing, and interference patterns for immaculate clarity.Hyper-Realistic Video Quality Empowered by HDR 10 TechnologySupercharged by HDR10 support with BenQ’s exclusive Auto HDR Colour Rendition, LK953ST’s 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.Optimize Image Quality with 4K Image Amplifying TechnologyTo ensure the best image quality, BenQ LK953ST adopts the cutting-edge 4K Image Amplifying Technology to further enhance the quality of projected images. LK953ST automatically upgrades the resolution of all projected images to 4K, guaranteeing superb image details. Additionally, LK953ST also comes with Pixel Enhancer 4K, a motion-adaptive edge enhancement feature that detects changes in the colour between an object and its background to produce sharp edges and precise surface textures.DLP Technology for Lasting Vibrant ColourBenQ 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 colours and pristinely legible text over countless uses.Vivid Clarity in Bright Ambient EnvironmentsLK953ST’s 5000lm high brightness produces wondrous displays in bright, compact exhibition spaces with superb image quality.Laser-Powered Ultra-High ContrastLK953ST laser projector creates strikingly clear images with stratospherically high 3,000,000:1 contrast ratio for true deep blacks, vivid rich colours and fine subtle details. LK953ST also features spontaneous response, requiring no wait to turn on or resume from blanking in true black for flexible performance capability.Digital HDMI Output for Multi-Screen ProjectionIn exhibition spaces and public venues, multiple projected screens can capture the audience’s imagination with immersive viewing experiences. Two projectors can also be stacked to double the brightness for a single image. Conventional projectors provide an analog-signal VGA output, which can decay due to transmission distance. BenQ LK953ST delivers a perfect digital signal via HDMI output directly from projector to projector or other display devices with no signal degradation for intensely bright stacked projection and beautifully mirrored multiple displays in showrooms, professional exhibits, and trade shows. (*Supports resolution up to 4K 30p)DICOM X-ray ImagingDICOM (Digital Imaging and Communication in Medicine) is a standard for handling, storing, printing and transmitting medical imaging information.
