Our Verdict

Samsung CHG70

AOC CQ27G1

The Samsung CHG70 is better than the AOC CQ27G1. The Samsung supports HDR, can get much brighter, has much better gradient handling, and the response time is quicker. The Dell is also compatible with NVIDIA graphics cards despite having native FreeSync support, while the AOC isn't. On the other hand, the AOC has a bit better contrast ratio and the out-of-box colors are more accurate.
