World's best eye comfort
This monitor is TÜV 5-star certified for eye comfort, featuring category one hardware low blue light certification.
Reduces blue light
The world’s first monitor to achieve TÜV category one hardware low blue light certification, reducing harmful blue light emissions to ≤20% for all day eye comfort without sacrificing colour accuracy. This is up to 60% less exposure than competitors.
Adapts to your environment
A built-in Ambient Light Sensor intelligently adjusts brightness and colour temperature to suit your surroundings, delivering consistent comfort day or night.
Smoother visual experience

The low reflectance panel reduces glare from outside light sources and improves screen contrast.
Exceptional contrast and accurate colour
IPS Black panel technology delivers a 2000:1 contrast ratio for deeper blacks, while 99% DCI-P3 and Display P3 colour coverage with Delta E <1.5 ensure vivid, precise colour.
Seamless multitasking
Multitask effortlessly on the world’s first monitor to implement Picture-by-Picture (PbP) with Screen Partition. Connect to two PCs simultaneously and display content across four unique partitions. No external hardware needed.
Connect up to four PCs
Picture-by-Picture (PbP) lets you view content from multiple PCs on one screen. The KVM (Keyboard, Video, Mouse) and Auto KVM features empower you to control them with a single keyboard and mouse.
