DELL UltraSharp U3425WE 34" WQHD 120Hz Curved Monitor

Ultra-wide curved monitor

The Dell UltraSharp U3425WE is a 34.14-inch curved display with a 21:9 aspect ratio and WQHD resolution of 3440 x 1440. It uses IPS Black technology to achieve a 2000:1 contrast ratio and covers 98% of the DCI-P3 color space with 1.07 billion colors. The 120Hz refresh rate and 5ms response time suit creative professionals and gamers who want fluid motion across an expansive desktop.

Sustained visual comfort

An integrated Ambient Light Sensor automatically adjusts brightness and color temperature to match surrounding conditions during long sessions. ComfortView Plus reduces harmful blue light emissions to 35%, down from 50% on the prior design, while maintaining color accuracy. The 300cd/m² peak brightness and antiglare 3H coating further limit eye strain, and the 5-Star Eye Comfort certification confirms consistent performance over time rather than only in brief tests.

Thunderbolt hub connectivity

The monitor functions as a Thunderbolt hub with included DisplayPort, HDMI, Thunderbolt and USB-C cables for a single-cable docking setup. Internal Multi-Stream Transport (iMST) splits the ultrawide panel into two 1720x1440 virtual displays for multitasking without a second physical screen. Builders who need more than two virtual partitions or who require a different video-input standard should verify their workflow matches these capabilities.
