Our Verdict
Dell S2721DGF
Samsung Odyssey G5 C27G55T
The Dell S2721DGF is much better than the Samsung Odyssey G5 C27G55T overall. The Dell has better gaming performance due to its higher refresh rate, faster response time, and lower input lag. It also has wider viewing angles, higher peak brightness, and significantly better ergonomics. However, the Samsung's VA panel has a better contrast ratio, and it has a Black Frame Insertion feature to improve motion clarity.
