Overview
The Dell S3225QC is a 31.5-inch QD-OLED monitor built around single-cable laptop setups, with 90 W of USB-C power delivery. It offers 4K UHD resolution, 139 ppi pixel density, 250 nits typical brightness (1000 nits peak) and 100% sRGB and 99% DCI-P3 coverage. The panel refreshes at 48–120 Hz, quotes 0.03 ms GtG response and supports FreeSync Premium. Inputs include 1× HDMI 2.1 and USB-C 90 W. The stand offers 110 mm of height adjustment and swivel. 5 × 5 W speakers are built in, and it weighs 10 kg with the stand. It suits laptop users who want one-cable docking at the desk. The main trade-off: 250 nits typical SDR brightness is lower than many LCD rivals.
