Our Verdict

MSI Optix MAG271CQR

AOC CQ27G1

The MSI Optix MAG271CQR is a slightly better monitor than the AOC CQ27G1. Both are 144Hz, 1440p monitors, but the MSI has a much better response time for gaming, it can get brighter, does a better job at handling reflections, and it has better viewing angles. Meanwhile, the AOC has much better black uniformity, better ergonomics, and much more accurate out-of-box colors. The MSI is better suited for bright rooms, while the AOC performs better in the dark.
