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.

AOC 27G4HRE200 Hz

Manufacturer specification · At the native panel resolution. Manufacturer lists 200 Hz. Available modes depend on input, cable and source. Listed vertical input range: 48-200Hz.

AOC 27G4ZR240 Hz

Manufacturer specification · At the native panel resolution. Manufacturer lists 260Hz (OC, 240Hz Native). The overclocked setting is listed separately and is not a guaranteed stock mode. Available modes depend on input, cable and source. Listed vertical input range: 48-260Hz.

Explore the full specifications

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.

WHAT EACH CHOICE ASKS OF YOU

What it brings and what to check

AOC 27G4HRE

What it brings

  • The 1920 × 1080 panel supports a listed 200 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.

What to check

  • Allow for the 177.4 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.

AOC 27G4ZR

What it brings

  • The 1920 × 1080 panel supports a listed 240 Hz native-resolution mode. Check the input-specific conditions alongside the figures.
  • The supplied stand has a listed 130 mm height adjustment, allowing its position to change without adding a separate mount.

What to check

  • The advertised 260 Hz setting is an overclock. The listed native configuration is 240 Hz; the higher setting needs the supported configuration and is not guaranteed stock operation.
  • Allow for the 207.7 mm listed depth with the supplied stand, plus cable clearance. Check desk depth before choosing this size.
