Our Verdict
AOC AGON AG271QX
ASUS PB277Q
The AOC AGON AG271QX is better than the ASUS PB277Q. The AGON AG271QX is a gaming-oriented monitor and has a much higher native refresh rate, so fast motion looks much smoother. The AOC also has better dark room performance with a higher native contrast ratio and better black uniformity.
