Our Verdict
Dell S2721DGF
ASUS ROG Strix XG16AHPE
The Dell S2721DGF and the ASUS ROG Strix XG16AHPE are two very different displays with different intended use cases. The Dell is a desktop monitor with a high-resolution screen and excellent ergonomics. The ASUS is a portable gaming monitor with a smaller screen and a lower native resolution. The Dell supports HDR, but it's not as accurate out of the box.
