Dell 34 Plus USB-C S3425DW
A sensible, well-connected ultrawide for spreadsheets and timelines that doesn't try to compete on image quality.

Our verdict
The S3425DW is a 34-inch curved ultrawide that adds 65W USB-C charging and video to a mainstream VA panel running at 120Hz. EFTM found color accuracy and uniformity strong for office work, while Digital Camera World measured less gamut coverage than Dell claims and saw uneven brightness. The stand adjusts for height and tilt but does not swivel, and EFTM found it sits too low. It is a productivity screen first, adequate for casual games but not built for fast competitive play.
