# Dell U4025QW UltraSharp 40-inch 5K WUHD Curved Display Thunderbolt Hub Monitor

Every aspect of your work springs to life on this curved 5K monitor featuring a 120Hz refresh rate. You'll never miss a single detail.  

### 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 optimizes brightness and color 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 color accuracy.

### Internal Multi-Stream Transport (iMST)
