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.

WHAT EACH CHOICE ASKS OF YOU

What it brings and what to check

AOC CU34G4

What it brings

  • The 3440 × 1440 panel supports a listed 180 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

  • Allow for the 269.4 mm listed depth with the supplied stand, plus cable clearance. Check desk depth before choosing this size.
  • AOC's table claims 1.07 billion colours (10-bit over DisplayPort at 120 Hz with 4:2:2/4:2:0), but its user guide lists 16.7M colours and the page also says True 8-bit colour, so treat 10-bit support as unconfirmed.

ASUS ROG Strix XG349C

What it brings

  • Published monitor interfaces and configuration are available from the exact-model ASUS specification source.

What to check

  • Compatibility and maximum operating modes depend on the source’s stated hardware, firmware and connection requirements; manufacturer figures are not independent measurements.
