Our Verdict

AOC Q27G3XMN

Xiaomi G Pro 27i

The AOC Q27G3XMN and the Xiaomi G Pro 27i are competing budget-friendly 1440p monitors. They each have Mini LED backlighting, with the Xiaomi having 1,152 zones and the AOC having 336 zones, but both of their local dimming features are good. The main advantage of the Xiaomi is that it gets much brighter, especially in SDR, so it's the better choice for use in well-lit rooms. The Xiaomi also displays a wider range of more vivid colors, leading to images that pop. While they both have a fast response time and some motion blur, the AOC has more black smearing. That said, the AOC has an advantage when it comes to console gaming because it can downscale 4k signals.
