Xiaomi A27Ui - 27" 4K Monitor

The Xiaomi 4K Monitor A27Ui is designed to deliver exceptional visual clarity and professional-grade colour performance for creators, designers, photographers, office professionals, and multitaskers. Featuring a 27-inch IPS display with an ultra-sharp 3840 × 2160 4K UHD resolution, every image, document, and video is presented with remarkable detail and crispness. The wide 178° viewing angle ensures consistent image quality from virtually any perspective, while HDR10 support enhances contrast and depth for more realistic visuals.

Professional colour accuracy is achieved through factory colour calibration with an average ∆E<1, ensuring highly accurate colour reproduction suitable for image editing, graphic design, video production, and other colour-sensitive workflows. With support for 1.07 billion colours, 100% sRGB, and 95% DCI-P3 colour gamut coverage, vibrant, lifelike colours are consistently displayed across compatible Xiaomi and Redmi devices for a seamless multi-device experience.

Productivity is enhanced through the versatile USB-C connection that supports audio, video, data transmission, and up to 90W reverse charging for compatible laptops using a single cable. An integrated USB hub allows additional peripherals such as a keyboard, mouse, or USB storage device to be connected directly to the monitor, helping maintain a clean and organised workspace. The three-sided narrow bezel design also provides an immersive multi-monitor setup with minimal visual interruption.

Long working sessions are made more comfortable with TÜV Low Blue Light Certification and DC dimming technology, which help reduce blue light exposure and screen flicker. The multifunctional ergonomic stand supports height adjustment, portrait mode, horizontal rotation, tilt adjustment, and VESA wall mounting compatibility, allowing the monitor to be positioned for maximum comfort and efficiency in any workspace.
