Our Verdict
ASUS ProArt Display PA278QV
Dell S2721D
The ASUS ProArt Display PA278QV is much better than the Dell S2721D. The ASUS has significantly better ergonomics, it gets brighter, and has wider viewing angles. It also has better color accuracy out-of-the-box, faster response time, and a Black Frame Insertion feature. The Dell has better reflection handling and a slightly better SDR color gamut.
