AOC AGON AG271UG 4K 60Hz G-Sync Monitor Review

The four buttons used to control this monitor’s OSD seem like a simple enough selection but as with many other AOC displays they have one silly layout issue. When moving through the several vertical lists of options that are in the menus, rather than the Left and Right buttons corresponding to moving up and down, as you’d expect, they work the opposite way round.

This one thing alone makes it decidedly frustrating to use and it’s not helped by the menus themselves looking drab and rather utilitarian.

Otherwise, though, the overall menu layout is intuitive and the selection of settings is ample. Brightness, contrast, gamma and colour balance can all be tweaked to get the best overall image quality.

There’s also a Game Color option, which is basically a vibrancy setting that at 0 makes the picture greyscale and at 200 totally over-saturates colour. We’re not sure why you’d ever want to change this unless radioactive colours are your thing.

As for Shadow Control, it’s essentially a gamma adjustment setting that increases the brightness of dark colours as you turn it up. This is useful for making it easier when gaming to see if any enemies are lurking in the dark.

Meanwhile, you can also choose from several Game Mode options. These just adjust several of the existing settings such as Shadow Control and Overdrive to optimise them for different genres; the options are FPS, RTS, Racing and Gamer.

The overdrive setting is the main means of adjusting the gaming performance of this monitor. Its default setting is Medium but it also offers Weak, Light and Strong settings, as well as the option to turn it off completely. We were happy with Medium as it offers a good balance of improved pixel response without too many of the artefacts introduced by overly aggressive overdrive.

Rounding things out, there’s also a low blue light option that helps reduce eye strain.
