Our Verdict
LG 27UK650-W
Dell S2719DGF
These are two different types of monitors, each with their advantages and disadvantages. The LG 27UK650-W, however, performs better in most uses except gaming. The LG has wider viewing angles, supports HDR, and has better dark room performance, although it still isn't too great. The Dell S2719DGF, on the other hand, has a TN panel with an extremely fast response time, and in conjunction with the lower input lag, it's a better choice if gaming is your primary use and you sit straight in front.
