How to read this comparison
  • Manufacturer facts for the exact models shown. Not a quality rating or a test result.
  • “Different” means the known values differ, not that one is better.
  • Missing or conflicting evidence is marked and never counts as a difference. Source chips hold each fact’s sources and conditions.

Match the monitor to the connection. Refresh limits depend on the input, cable and source device. Confirm the exact regional ports, stand adjustment and mount. Manufacturer response-time methods such as MPRT and GtG are different; neither the image nor these figures establish an independent motion or colour-quality test.

Manufacturer specification · AOC's UK page lists 'QHD@260Hz / HD@400Hz'. The 400 Hz figure applies only in the lower-resolution HD Dual Resolution mode, not at the native panel resolution, and the page's per-input vertical row (48~144Hz HDMI / 48~260Hz DisplayPort) does not state which input carries it; the input limits and OverClock states are from the CQ27G4Z2 user manual.

WHAT EACH CHOICE ASKS OF YOU

What it brings and what to check

AOC C27G4Z2

What it brings

What to check

  • Response time, HDR support and colour figures are manufacturer claims with different conditions; they do not establish independent motion or image-quality results.
  • Allow for the 239.4 mm listed depth with the supplied stand, plus cable clearance. Check desk depth before choosing this size.

AOC CQ27G4Z2

What it brings

What to check

  • The headline maximum spans different resolution modes: QHD@260Hz / HD@400Hz. The faster lower-resolution mode does not deliver the same pixel detail as the native panel mode.
  • Allow for the 239.4 mm listed depth with the supplied stand, plus cable clearance. Check desk depth before choosing this size.

Manufacturer specification · AOC's UK page lists 'QHD@260Hz / HD@400Hz'. The 400 Hz figure applies only in the lower-resolution HD Dual Resolution mode, not at the native panel resolution, and the page's per-input vertical row (48~144Hz HDMI / 48~260Hz DisplayPort) does not state which input carries it; the input limits and OverClock states are from the CQ27G4Z2 user manual.

AOC's UK page advertises a Low Input Lag mode (feature tile: 'switching to the AOC Low Input Lag mode') and its introduction says low input lag keeps every action precise and responsive, but the exact-model user manual's complete Game Setting menu (Gaming Mode, Shadow Control, Game Color, Adaptive-Sync, Dial Point, MBR, MBR Sync, Overdrive, Frame Counter, OverClock) has no Low Input Lag setting. Whether a selectable low-input-lag mode exists is not resolved, and no input-lag figure is published. · Manufacturer specification
