Dell UltraSharp U3425WE 34" 120Hz WQHD Curved IPS Monitor with Thunderbolt Hub
Create an expansive professional workspace with a 34.14-inch curved WQHD IPS Black display, smooth 120Hz performance, calibrated wide-gamut colour and Thunderbolt 4 connectivity with up to 90W laptop power delivery.
An expansive curved ultrawide workspace
The Dell UltraSharp U3425WE combines a 34.14-inch, 21:9 display with 3440 x 1440 WQHD resolution, providing generous horizontal room for documents, spreadsheets, communication tools, creative applications and multi-window productivity.
Its 1900R curvature brings the edges of the ultrawide display into a comfortable viewing position, while IPS Black technology provides wide 178-degree viewing angles and a 2000:1 typical contrast ratio.
Smooth performance at 120Hz
A refresh rate of up to 120Hz helps scrolling, window movement and everyday on-screen transitions appear smoother than on a conventional 60Hz business monitor.
Professionally calibrated colour
The display covers 98% DCI-P3, 98% Display P3, 100% sRGB and 100% BT.709. Average Delta E below 2 supports accurate and consistent colour across professional applications.

Integrated stereo speakers
Two built-in 5W speakers provide convenient audio for video meetings, presentations, training content and everyday multimedia without requiring separate desktop speakers.
Automatic viewing adjustment
An integrated ambient light sensor can automatically adjust screen brightness and colour temperature according to surrounding lighting conditions.
The monitor also features 5-star eye-comfort certification, an anti-glare screen coating and a smooth 120Hz refresh rate to support comfortable viewing during extended work sessions.
Advanced hub connectivity
The U3425WE provides a central connection point for compatible computers, additional monitors, USB accessories, audio equipment and high-speed wired networking.
Thunderbolt 4, DisplayPort and HDMI provide flexible display connections, while the integrated 10Gbps USB hub keeps commonly used desktop devices accessible.
