THE DIFFERENCES, MADE VISIBLE

Visual facts

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 CU34G4CA

What it brings

  • The 3440 × 1440 panel supports a listed 180 Hz native-resolution mode. Check the input-specific conditions alongside the figures.
  • A listed charging output reaches 90 W on the specified USB-C or Thunderbolt port. Match the laptop and cable to that port’s power and display capabilities.

What to check

  • The 90 W charging ceiling may not replace the original charger for a laptop that needs more power. The rating applies only to the stated port.
  • Allow for the 269.4 mm listed depth with the supplied stand, plus cable clearance. Check desk depth before choosing this size.

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.
