Our Verdict
Dell S2719DGF
Dell S2721DGF
The Dell S2721DGF is much better overall than the Dell S2719DGF. The S2721DGF has a faster refresh rate, and the IPS panel delivers much better viewing angles. The S2721DGF adds HDR support, but due to the low peak brightness and disappointing contrast, this doesn't add much.
