Our Verdict
ASUS PB277Q
LG 27UK650-W
The ASUS PB277Q and the LG 27UK650-W are very different monitors. The ASUS is a 1440p TN monitor, while the LG is a 4k IPS monitor. For the most part, the LG performs better because it has a higher resolution, better contrast ratio, and wider viewing angles. Also, it supports VRR and HDR, whereas the ASUS doesn't. That said, the ASUS has a 75Hz refresh rate compared to the LG's 60Hz, and its response time is much faster, resulting in clearer motion.
