DELL UltraSharp U3425WE 86.7cm (34") WQHD IPS 120Hz HDMI/DP/Thunderbolt/LAN curved monitor

The world's first 34-inch monitor with 5-Star Eye Comfort certification

The Dell UltraSharp U3425WE is designed for users who need the perfect combination of comfort, performance, and sustainable design. Its curved, ultrawide WQHD display with a 120Hz refresh rate delivers a smooth visual experience, reduced flicker, and natural sharpness when working with multiple windows at once. The built-in Ambient Light Sensor automatically adjusts brightness and color temperature, while enhanced ComfortView Plus technology reduces blue light emissions to <35%, enabling all-day comfort without losing color accuracy.

The monitor offers exceptional color coverage - 98% DCI-P3 and Display P3 - and IPS Black technology with deeper blacks and a contrast ratio of 2000:1. The Internal Multi-Stream Transport (iMST) feature allows you to split the screen as if you were using two separate monitors, without additional software.

With Thunderbolt 4 connectivity and up to 90W of power delivery, you can power and connect your devices with a single cable. In addition, the monitor includes more than a dozen ports, including an RJ45 Ethernet port (up to 2.5GbE), allowing for easy integration into modern work environments. macOS compatibility is tested and optimized, making it an ideal companion for Apple device users as well.

For increased productivity, Dell Display and Peripheral Manager provides application scheduling, easy navigation across multiple devices, and centralized peripheral management. Dell Color Management software (Calman Verified) lets you accurately calibrate colors and create custom ICC profiles.

The Dell UltraSharp U3425WE is also environmentally friendly: it is made from 50% recycled steel, 85% post-consumer plastic, 100% recycled aluminum and at least 20% recycled glass. The packaging is made from 100% renewable materials and the monitor is EPEAT Gold Climate+ registered, confirming the highest environmental standards.

Same summary

The DELL UltraSharp U3425WE 34" monitor focuses on a wide working area and image clarity, which is especially useful for business users, those who regularly multitask or do analytics, and anyone who works with multiple windows at the same time. Due to the combination of a curved ultrawide format, high QHD resolution and IPS panel, it proves to be a good solution where visibility, eye comfort and clearly displayed data are important. The monitor is less suitable for users who are limited by desk space or want very specific color settings for professional graphics work, and is also not optimal for top esports players, where the highest refresh rates are crucial. The possibility of using it as an alternative to a dual monitor stands out, as it offers a consistent, continuous working area.
