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.

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 U27G4XM

What it brings

  • The 3840 × 2160 panel supports a listed 160 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 headline maximum spans different resolution modes: UHD 3840 × 2160 at 160 Hz / FHD 1920 × 1080 at 320 Hz (Dual Frame Mode). The faster lower-resolution mode does not deliver the same pixel detail as the native panel mode.
  • Allow for the 240 mm listed depth with the supplied stand, plus cable clearance. Check desk depth before choosing this size.
