Our Verdict

Dell S2722QC

Dell P2423D

The Dell P2423D and the Dell S2722QC are both designed for productivity work. The S2722QC is the better monitor for most people, as it can display content in HDR, is better at overcoming bright glare, and has a more detailed image. It also supports DisplayPort Alt mode with 65W of power delivery, so you can connect your laptop to display an image and charge it with the same cable. However, the P2423D is more compact, so you may prefer it if you have limited space or want a dual or triple monitor setup.
