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.

WHAT EACH CHOICE ASKS OF YOU

What it brings and what to check

AOC 25G4KUR

What it brings

  • The 1920 × 1080 panel supports a listed 400 Hz native-resolution mode. Check the input-specific conditions alongside the figures.
    Manufacturer source
  • The supplied stand has a listed 130 mm height adjustment, allowing its position to change without adding a separate mount.
    Manufacturer source

What to check

  • The advertised 420 Hz setting is an overclock. The listed native configuration is 400 Hz; the higher setting needs the supported configuration and is not guaranteed stock operation.
    Manufacturer source
  • Allow for the 207.6 mm listed depth with the supplied stand, plus cable clearance. Check desk depth before choosing this size.

AOC's UK specification lists 'Response time GtG 1 ms' (and its Fast IPS text says up to 1ms GtG), while the same page's feature section is headed '0.5ms Response time GTG'. The page contradicts itself, so the claim is left unresolved. · Manufacturer specification
