Our Verdict
Acer Nitro XV275K P3biipruzx
AOC Q27G40XMN
The Acer Nitro XV275K P3biipruzx and the AOC Q27G40XMN are both gaming monitors with Mini LED backlighting. There are a few differences between them, though, as the Acer is versatile for more uses. It has a higher 4k resolution, resulting in sharper text and more detailed images, ideal for work or content creation. On top of that, the Acer's better ergonomics and wider viewing angles make it a superior choice for sharing your screen with others. The Acer also supports HDMI 2.1 bandwidth to take advantage of gaming consoles, which the AOC doesn't support. The AOC does have a few advantages, though, as it has a higher native contrast ratio and better local dimming feature, making it the better choice for watching content in dark rooms.
