Our Verdict
Dell S2721DGF
Dell S2721HGF
Overall, the Dell S2721DGF performs better than the Dell S2721HGF. The S2721DGF has a 1440p resolution compared to the S2721HGF's 1080p and a higher 165Hz refresh rate. It also has a better response time at max refresh rate and 60Hz, resulting in clearer images in fast-moving scenes. The S2721DGF has an IPS panel with much wider viewing angles, and the stand allows for more ergonomic adjustments, making it a better choice for sharing content or playing co-op games. If you often game in the dark, the S2721HGF might be a better choice due to its higher contrast ratio.
