Our Verdict

AOC Q27G40XMN

Acer Nitro XV275K P5biipruzx

The AOC Q27G40XMN and the Acer Nitro XV275K P5biipruzx are both Mini LED monitors. The Acer is higher-end with a higher 4k resolution for sharper text and HDMI 2.1 bandwidth to take full advantage of gaming consoles. The Acer also has a few extra gaming features, like a dual mode that switches it from 4k, 160Hz to 1080p, 320Hz for better versatility with different types of games. However, the AOC has much better picture quality. It has a VA panel with a higher native contrast ratio, and its local dimming feature is much more effective at improving the picture quality with deeper blacks and less haloing around bright objects. Plus, you can only use the local dimming feature on the Acer in HDR, so the picture quality is much worse in SDR with blacks that look gray.
