Excellent Color and Contrast from Any Viewing Angle | ASUS Off-Axis Contrast Optimization (OCO) technology

Direct type LED backlight displays have narrow viewing angles, which can make collaboration with clients or colleagues on colour-critical work challenging due to inaccurate colours being displayed to viewers seated to the side.

ASUS Off-Axis Contrast Optimization (OCO) technology solves this problem with a compensation layer that controls light transmittance around the edges, reducing halo effects by 80%* and providing a 7X* contrast-ratio enhancement for dark parts of the image when viewing the screen from an angle.

World's 1st 27-inch 4K Monitor with Mini LED Backlight

ASUS ProArt PA27UCX-K 4K monitor incorporates the leading technology of mini LED backlight, which is packed in physically half smaller LEDs than the conventional in more densely to increases the granularity of brightness control. ProArt PA27UCX-K offers individual backlight control of a whopping 576 zones with higher luminance and deeper darkness to deliver the best contrast and accurate reproduction of HDR contents.

ASUS Smart HDR Technology

ASUS ProArt PA27UCX-K features ASUS Smart HDR Technology, which supports multiple HDR (high-dynamic-range) formats and multiple PQ curves to suit content creators' specific requirements. Dolby Vision HDR transforms your viewing experience with ultra-vivid image — incredible brightness, contrast, and colour to expand content creators' storytelling possibilities. It achieves this astonishing image quality through cinema-inspired HDR technology that can deliver billions of colours. HDR-10 support ensures compatibility with existing streaming video services and a growing list of HDR-enabled games, including PQ hard clip curve, PQ Optimized and PQ Basic, to cover all content creators' needs. The PA27UCX-K's HLG (hybrid log gamma) preset allows users to both immerse in, as well as create material for broadcast and satellite TV platforms such as the BBC iPlayer, Japan NHK TV, and DirecTV.

The Most Flexible Hardware Calibration

Whether you're using a desktop, laptop, PC or Mac, ASUS ProArt™ Hardware Calibration offers colour accuracy tuning and uniformity compensation to make things easy when it's time to recalibrate your display's brightness and colour consistency.

  • Seamless Calibration | ProArt displays are compatible with most major calibrators, including those from X-Rite, Datacolor and Klein, and also work seamlessly with Calman and Light Illusion ColourSpace CMS professional hardware calibration software to make calibration faster and easier. (Calman and Light Illusion ColourSpace CMS software are not included with ProArt PA27UCX-K)
  • Colour Accuracy Optimization | ASUS ProArt™ Calibration lets you optimize colour space settings for different content. Besides sRGB, you can create advanced setups comprising of five different colour spaces and other customized settings.
  • Uniformity Compensation | ASUS ProArt™ Calibration gives you 3x3 and 5x5 uniformity compensation matrices to ensure consistent brightness throughout the screen to reduce colour shift.
  • Saved colour parameter profiles | The ASUS ProArt™ Calibration Technology saves all colour parameter profiles on the ProArt™ monitor's internal scaler IC chip instead of the PC. This lets you connect your monitor to different devices without needing to continuously change existing settings. It also reduces the signal distortion between the IC and the LCD optical spectrum. The colour profiles can be easily activated by using the hotkey on the monitor next time without a PC or calibrators.

Industry Leading Color Fidelity for Truly Expressive Hues

ProArt PA27UCX-K is factory pre-calibrated using a new, three-scale process to guarantee industry-leading colour fidelity. The display then undergoes stringent testing using ASUS advanced grayscale tracking technology to ensure smoother colour gradations, better uniformity and high colour accuracy with an industry-leading delta-E (△E) < 1 colour difference value. Each grayscale level is also carefully measured and set to ensure compliance with the precise DICOM standard.
