Enjoy seamless multitasking, superior visual clarity, and all day eye comfort while reducing desk clutter.
Experience breathtaking clarity on a curved screen with a cinematic 21:9 aspect ratio, 129 pixels per inch, and IPS Black technology for exceptional detail and deeper contrast.

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
Enjoy less flicker and seamless scrolling with a 120Hz refresh rate, creating smoother motion.

Low reflectance panel
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.

Thunderbolt 4
Power your devices with a single cable connection with up to 140W EPR (Extended Power Range) enabled by Thunderbolt 4.

Extensive connectivity
Connect all your devices with a multitude of ports, including a pop-out quick access module featuring two USB-C ports (up to 27W power delivery) and one USB-A port.

Stable connection
Connect to the Ethernet with a built-in RJ45 port with up to 2.5GbE. The Ethernet Switch mode feature gives you the flexibility to lock the wired Ethernet to a chosen PC while continuing to share one set of peripherals to control multiple PCs.

Effortless deployment and setup
This monitor is purpose-built with lightweight aluminium and a VESA-mounting solution for easy installation and flexible management.
Quick and simple setup
Replace a multiple monitor setup with a single, lightweight monitor for easier installation and reduced setup time. The 2m Thunderbolt cable powers your laptop and keeps your desk clutter-free with a single connection.
IT-friendly flexibility
Designed for VESA mounting, this monitor offers flexibility to fit your workspace. Pair it with the Dell Pro Heavy Duty Single Monitor Arm - HDA26 sold separately from February 2026 for a complete solution.
