Our Verdict
AOC AGON AG271QX
Samsung CHG70
The Samsung CHG70 is better than the AOC AGON AG271QX. The Samsung has better native contrast than the AG271QX, important for dark room viewing, although the AG271QX has better black uniformity. The AG271QX has a slightly faster response time, but the CHG70 has an optional black frame insertion feature that can improve motion by reducing persistence blur. Finally, the CHG70 supports HDR and can display a wide color gamut.
