References also use labels such as “QUXGA Wide,” “QUXGA-W,” and “UHD+.” A Japanese court decision dated 2025-03-28 uses “QUXGA Wide” for 3840 × 2400 in a passage about logical screen resolution; the English label here describes the Japanese text rather than quoting an English original. These aliases should not be treated as universally settled equivalents. Fourmilab author John Walker wrote in a technical reference dated 2006-07-10, “Nomenclature for wide screen display modes is far from settled.”
