Our Verdict
AOC Q27G3XMN
Acer Nitro XV275U P3biipx
The AOC Q27G3XMN and the Acer Nitro XV275U P3biipx are competing entry-level monitors with many of the same features. While they each have Mini LED local dimming, the AOC is just a bit better as it has less blooming. However, the Acer is the better choice if you need something for a well-lit room as it gets brighter. On the other hand, the AOC has an advantage for gaming thanks to its faster response time.

Hey, it really depends on your preferences, and even how far you sit from the monitor. Generally speaking, a 4k display has better text clarity, but you get diminishing returns as you sit further away because our eyes can’t perceive the difference as much from a distance. You can read more about it here.
Hi, how much more noticeable is a difference of 4k vs 1440p on a 27in monitor like these?
