Our Verdict

AOC AGON AG271QX

ViewSonic XG2402

The AOC AGON AG271QX is slightly better than the ViewSonic XG2402. The AG271QX is better at displaying large areas of similar color, as it supports 10-bit color. However, the main advantage of the AGON AG271QX is the larger, higher resolution screen, that makes it much easier to see fine details in games and for multitasking.
