Dell UltraSharp 40 Curved Thunderbolt Hub Monitor (U4025QW)

Smoother visual experience
A 120Hz refresh rate delivers less flicker, more seamless scrolling and smoother motion than 60Hz monitors.

Ambient Light Sensor
A built-in Ambient Light Sensor intelligently optimises brightness and colour temperature based on your surroundings.

Improved ComfortView Plus
Our latest monitors reduce harmful blue light emissions to <35%, compared to <50% from the previous generation, for all-day eye comfort without sacrificing colour accuracy.

Internal Multi-Stream Transport (iMST)
Partition your display as if there were two 2560x2160 physical monitors instead of one. No external software or DisplayPort splitter needed.
