Our Verdict
Dell S2721DGF
LG 27GP950-B
The LG 27GP950-B is slightly better than the Dell S2721DGF. The LG has a higher resolution and much better text clarity, and it supports HDMI 2.1 for next-gen console gamers. The Dell, on the other hand, has much better reflection handling and much better ergonomics.
