Overview
The Dell U3224KB is a 31.47-inch IPS monitor with 6144 × 3456 resolution and colour coverage that suits creative work. It offers 224 ppi pixel density, 400 nits typical brightness (600 nits peak), 2000:1 static contrast and 100% sRGB and 99% DCI-P3 coverage. The panel refreshes at 60 Hz. Inputs include 1× HDMI 2.1, 1× DisplayPort 2.1, Thunderbolt 4 and 7× USB-A. The stand offers 160 mm of height adjustment, swivel and pivot. Speakers are built in, and it weighs 11.9 kg with the stand. It suits colour-sensitive work such as photo and video editing. The main trade-off: capped at 60 Hz, so fast games will not feel as smooth.
