Overview
The Dell S3423DWC 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, 350 nits typical brightness, 3000:1 static contrast and 99% sRGB coverage. The panel refreshes at 48–100 Hz, quotes 4 ms response and supports FreeSync. Inputs include 2× HDMI 2.0, USB-C 65 W and 2× USB-A. The stand offers 100 mm of height adjustment. 2 × 5 W speakers are built in, and it weighs 10.53 kg with the stand. It suits laptop users who want one-cable docking at the desk. The main trade-off: heavy at 10.53 kg, so it needs a sturdy desk or arm.
