Our Verdict

LG 27GL850-B/27GL83A-B

AOC CQ27G2

The LG 27GL850-B/27GL83A-B is much better than the AOC CQ27G2 for most uses. They use different panel technologies, each with their own strengths and weaknesses. The 27GL850-B has wider viewing angles, much faster response times, and higher peak brightness. The 27GL850-B supports HDR, but this doesn't add much. On the other hand, the AOC CQ27G2 has a much higher native contrast ratio, resulting in much deeper blacks.
