Our Verdict
Dell S2721QS
Dell P2425H
The Dell S2721QS and the Dell P2425H are office-oriented monitors. Both are good choices for office work, and if you don't need the added performance of the S2721QS, then the P2425H is a great choice. However, the S2721QS is the better choice if you work in a bright environment, need HDR support, want a much sharper image, or prefer a larger screen.
