Our Verdict
AOC AGON AG271QX
Gigabyte AORUS AD27QD
The Gigabyte AORUS AD27QD is much better than the AOC AGON AG271QX. The AORUS supports HDR, which is great, and has much wider viewing angles. The AD27QD also has an optional black frame insertion feature, which can help reduce persistence blur. The AGON has better black uniformity and a slightly faster response time, but this likely isn't noticeable. The AGON also has more inputs and supports older analog inputs from DVI and VGA cables.
