Notes
The AOC manual carries an unusually explicit official DSC statement: "In order to reach QHD 240Hz 1.07 billion colors (RGB/YCbCr 4:4:4) for DP 1.4 (HBR3) signal input, a DSC-enabled graphics card must be used." (General Specification Note 2, p.33). Modelled as the DisplayPort 1440p/240Hz mode being DSC-required rather than as a GPU-generation gate (the manual names no minimum GPU series). HDMI 2.0 caps at 1440p/144Hz. Distinct SKU from the newer AG276QZD2 - not merged.
