Our Verdict

Dell S2721QS

Dell P2423D

The Dell P2423D and the Dell S2721QS are both budget-friendly office and productivity monitors. The S2721QS is the better monitor for most people, as it has a sharper display, is better at overcoming glare, and can view and edit HDR content. However, the P2423D is more compact, so you may prefer it if you have limited space or want a dual or triple monitor setup. The P2423D also has USB ports for connecting multiple peripherals to your computer with a single cable.
