Our Verdict
Acer Predator X27 bmiphzx
Dell Alienware AW3420DW
The Acer Predator X27 bmiphzx is much better than the Dell Alienware AW3420DW in most uses. Although the Acer has a smaller screen and a 16:9 aspect ratio, it has a much sharper 4k resolution, a higher refresh rate, and it supports HDR. The Acer also has significantly better viewing angles and peak brightness, but the Dell has a better build quality, much better color accuracy, as well as a lower input lag.
