Our Verdict
AOC CQ27G2
ASUS TUF Gaming VG27WQ1B
The ASUS TUF Gaming VG27WQ1B is a bit better overall than the AOC CQ27G2. The ASUS gets brighter, supports HDR, has a quicker response time at 60Hz, and a higher max refresh rate. However, the AOC has much better ergonomics, a quicker response time at its max refresh rate, and a lower input lag.
