  • 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.

Regional configuration

ASUS ROG Strix XG27ACSUK ASUS part 90LM09Q0-B01170. The US ROG page’s embedded data lists part numbers 90LM09Q0-B011B3 (schema.org) and 90LM09Q0-B011B0 (product partNo), and its where-to-buy button uses configuration 90LM09Q0-B011C1; it lists the same panel, refresh, input, power and stand-height figures. Neither US table lists the HDR (High Dynamic Range) Support, Speaker, Swivel, Pivot, 1/4" Tripod Socket, GameFast Input technology or Color Calibration E-report rows present in the UK table, and the second US table also omits Aspect Control (omissions, not contrary values). The second US table adds HDCP 2.2, Trace Free Technology, Color Temp. Selection (4 modes), Low Blue Light (Hardware Solution) and Backlight Type LED, which the UK table does not list.
