Our Verdict
LG 27GN950-B
Dell S2721DGF
The Dell S2721DGF is slightly better than the LG 27GN950-B for gaming. The Dell has much better ergonomics, significantly better reflection handling, a lower input lag, and a slightly quicker response time at its max refresh rate. However, the LG has a higher 4k resolution, better out-of-the-box color accuracy, a quicker response time, and a lower input lag at 60Hz.
