Our Verdict
Acer Predator X27 bmiphzx
Dell UltraSharp U2720Q
For most uses, the Acer Predator X27 bmiphzx performs better than the Dell U2720Q. While they both have the same screen size and resolution, the Acer has a much higher refresh rate of 144Hz and it supports G-SYNC to reduce screen tearing when gaming. In addition, the Acer has a faster response time, a higher HDR peak brightness, and it handles reflections better. However, the Dell has much better ergonomics and it comes with two USB-C ports, which the Acer doesn't have.
