Our Verdict
Acer Predator X27 bmiphzx
LG 27UK650-W
The Acer Predator X27 bmiphzx is slightly better than the LG 27UK650-W. The Acer Predator X27 supports local dimming and has better HDR performance, thanks to its wider color gamut and higher HDR peak brightness. The LG 27UK650-W has slightly lower input lag and feels more responsive, which is great for gaming.
