Our Verdict
AOC Q27G3XMN
AOC AGON PRO AG276QZD2
The AOC Q27G3XMN and the AOC AGON PRO AG276QZD2 are both 27-inch gaming monitors. The Q27G3XMN is the better choice, as it displays a wider range of colors more vividly in HDR, making it more immersive. However, the AG276QZD2 has better motion handling thanks to its faster response time.
