Check USB-C Power and Video Support
Verify that your laptop or desktop USB-C port supports DisplayPort Alternate Mode and can deliver up to 65W of power for charging. The monitor provides 65W Power Delivery over USB-C alongside video and data. Confirm your graphics output can drive 3440×1440 at 120Hz over HDMI 2.1 or USB-C. Ensure your operating system supports the 21:9 aspect ratio for correct scaling.
Built-In Audio and Ergonomic Stand
Dual 5W speakers (10W total) provide sound without external speakers, saving desk space and reducing cable clutter. The stand adjusts for height, tilt from 5° to 21°, and slant of 4° left and right for comfortable viewing. Narrow 0.33-inch side bezels minimise gaps in multi-monitor arrangements. A USB-C downstream port and USB-A ports on the monitor act as a hub for peripherals.

Questions sur cet article
Does the Dell S3425DW include the USB-C cable needed for 65W power delivery, or must I buy one separately?
The monitor ships with a USB-C cable that supports up to 65W power delivery, so no separate cable is required for charging a compatible laptop.
Should I choose this 34" UW-QHD 120Hz model or a smaller 1080p ultrawide for coding and media?
The 3440×1440 resolution on a 34" 21:9 panel gives roughly 2.3× the pixel count of 1080p ultrawide, fitting far more code lines and showing media at native 1440p without scaling.
What does the 120Hz refresh rate actually deliver when I connect a laptop over USB-C?
Over the USB-C upstream port the monitor runs at its full 120Hz with AMD FreeSync Premium and 1ms response time, provided the laptop's GPU supports that rate at 3440×1440.
