Notes
Headline 180Hz is DisplayPort-only; HDMI 2.0 caps at 1440p/144Hz (both quoted verbatim from the AOC manual). No mode requires DSC - the term never appears in the 32-page manual. No confirmed US SKU (UK/APAC storefronts only). The regional twin "Q27G4F" has its own separate AOC manual and is NOT confirmed to be identical hardware - deliberately not listed as an alias (PHASE 3C.2B correction F).
