Our Verdict
BenQ MOBIUZ EX321UX
Acer Nitro XV275K P5biipruzx
The BenQ MOBIUZ EX321UX and the Acer Nitro XV275K P5biipruzx are both 4k Mini LED monitors, with a few differences. With the BenQ, you can enable or disable local dimming as you wish, and it helps improve the picture quality with deeper blacks, but it has some haloing around bright objects. That said, the local dimming feature on the Acer has more haloing, and it automatically turns on in HDR, as you can't turn it off or use it in SDR. The BenQ has a few other advantages in picture quality as it gets much brighter and has more accurate colors. While the BenQ has better overall motion handling, the Acer is more versatile for playing different types of games. It has a dual-mode feature that switches its native 4k resolution and 160Hz refresh rate to 1080p, 320Hz for a smoother feel.
