Dell UltraSharp U3425WE 34" Curved Thunderbolt Hub Monitor
The Dell UltraSharp U3425WE is a 34-inch curved ultrawide monitor built for professionals who need immersive screen space and accurate color work. Its 3440×1440 resolution, 120Hz refresh rate, and Thunderbolt 4 hub make it suited to creative workflows, design studios, and multi-device setups where cable clutter matters.
Why this product
Ultrawide curved screen with 120Hz refresh
The 34-inch 3440×1440 display and 1900R curvature create an immersive field of view. 120Hz refresh reduces flicker and delivers smoother motion than standard 60Hz monitors.
Professional color accuracy for creatives
100% sRGB and 98% DCI-P3 color gamut with Delta E < 2 average ensures work stays color-accurate across print and digital output.
Thunderbolt 4 hub eliminates extra cables
Built-in USB-C hub with 4 Type-A ports, Ethernet, and audio output lets you connect peripherals directly to the monitor. 90W power delivery over Thunderbolt upstream port charges compatible laptops.
KVM switch for dual-computer workflows
Switch between two connected systems using keyboard, mouse, and monitor without manually unplugging cables.
Ergonomic adjustments and eye comfort
Height, tilt, and swivel controls let you position the screen for long work sessions. Ambient light sensor auto-adjusts brightness, and ComfortView Plus limits blue light emission to below 35%.
ENERGY STAR and EPEAT Gold certified

Trade-offs
