Key strengths

The 2560 × 1440 panel supports a listed 180 Hz native-resolution mode. Check the input-specific conditions alongside the figures.

The listed 100x100 VESA pattern gives a mounting option when the mount also meets the monitor’s weight and screw requirements.

The checks that matter.

Before you buy

Allow for the 197.6 mm listed depth with the supplied stand, plus cable clearance. Check desk depth before choosing this size.

The inspected table does not verify height adjustment. Confirm the stand’s adjustment range if fixed screen height would be a problem.

Conflicting sources

AOC's UK page lists a 'Sync range' of 48-310, which exceeds the same page's 'Max Refresh rate 180 Hz' and its DisplayPort vertical range (DP1.4: 48-180Hz); the linked Q27G42XNE user manual lists a vertical scan range of 48-144Hz (HDMI) and 48-180Hz (DisplayPort). The adaptive-sync range is left unresolved rather than presenting 48-310 Hz as usable.
