Overview
The Dell S3425DW is a 34-inch VA display that doubles as a laptop dock, thanks to 65 W USB-C power delivery. It offers UWQHD resolution, 109 ppi pixel density, 300 nits typical brightness, 3000:1 static contrast and 99% sRGB and 95% DCI-P3 coverage. The panel refreshes at 48–120 Hz, quotes 1 ms response and supports FreeSync Premium. Inputs include 2× HDMI 2.1, USB-C 65 W and 2× USB-A. The stand offers 130 mm of height adjustment. 2 × 5 W speakers are built in, and it weighs 9.38 kg with the stand. It suits laptop users who want one-cable docking at the desk. The main trade-off: heavy at 9.38 kg, so it needs a sturdy desk or arm.
