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.

Questions about this item
How much heat or power does the 34" 120Hz panel draw when it runs all day?
The monitor is ENERGY STAR and TCO certified for reduced power consumption, and its 300 cd/m² brightness is managed by an ambient light sensor that adjusts output to your surroundings.
What cables or host ports must I already have to use the Thunderbolt hub and 120Hz WQHD signal?
The box includes DisplayPort, HDMI, Thunderbolt 4 and USB-C cables, so you need a host with Thunderbolt 4 or USB-C video-alt-mode plus DisplayPort or HDMI for the 3440 x 1440 120Hz link.
Will my older GPU that only has HDMI 1.4 or DisplayPort 1.2 drive the 3440 x 1440 120Hz mode?
HDMI 1.4 and DisplayPort 1.2 lack the bandwidth for 3440 x 1440 at 120 Hz; you would be limited to 60 Hz unless the GPU supports newer DisplayPort or HDMI versions.
