Our Verdict

LG 27UK650-W

Dell U2719D

The LG 27UK650-W is much better than the Dell U2719D. The LG 27UK650-W can deliver much more uniform blacks, which is great for a dark room and supports HDR. The LG can display more content on the screen thanks to the native 4k resolution, and supports FreeSync to please gamers. The Dell U2719D has better ergonomics and is easier to place in a comfortable position.
