Our Verdict

Dell S2721DGF

HP OMEN 27i

The HP OMEN 27i and the Dell S2721DGF are very similar. They're both 27 inch IPS monitors with a 1440p resolution and 165Hz refresh rate. The Dell has better response times to deliver clearer motion with less blur trail behind fast-moving objects. It also has significantly better ergonomics because it can swivel and rotate to portrait mode, and it supports HDR.
