Our Verdict
ASUS ProArt Display PA278QV
Dell S2721QS
The ASUS ProArt Display PA278QV and the Dell S2721QS are both great productivity monitors. The main difference is that the ASUS has a 1440p resolution, while the Dell is 4k. The ASUS has USB ports, and its faster 75Hz refresh rate provides a slightly more responsive desktop experience. On the other hand, the Dell has a Picture-in-Picture mode and supports HDR.
