Our Verdict
AOC AGON AG271QX
Dell S2719DGF
The AOC AGON AG271QX is a bit better than the Dell S2719DGF. The AOC AGON AG271QX has much better black uniformity and thus less backlight bleed in very dark scenes in a dark room. The Dell S2719DGF, on the other hand, has slightly better ergonomics which can be helpful depending on your setup.
