Our Verdict
Dell S3221QS
Dell S2721QS
Overall, the Dell S2721QS is much better than the Dell S3221QS. Although they look similar, the S2721QS has wider viewing angles and significantly better ergonomics and gets brighter in SDR mode. However, the S3221QS' VA panel has a higher contrast ratio and is better suited for dark rooms, and its larger screen size provides more space for multitasking.
