Our Verdict
Acer Predator XB271HU Bmiprz
LG 27UK650-W
The LG 27UK650-W is a bit better than the Acer Predator XB271HU Bmiprz. The LG 27UK650-W is a 4k monitor that supports HDR. It supports FreeSync VRR, can get brighter than the Acer, and has better reflection handling. The Acer Predator, on the other hand, has better ergonomics and is easier to place comfortably. It has a lower input lag, supports G-SYNC VRR over a wider range of frequencies, and can offer you a tear-free gaming experience.
