Actual use is inconsistent. From https://en.wikipedia.org/wiki/2K_resolution https://en.wikipedia.org/wiki/2K_resolution: “In consumer products, 2560 × 1440 (1440p) is sometimes referred to as 2K, but it and similar formats are more traditionally categorized as 2.5K resolutions.” “2K” is used to denote WQHD often enough, whereas 1080p is usually called that, if not “FHD”. “2K” being used to denote resolutions lower than WQHD is really only a thing for the 2048 cinema resolutions, not for FHD.
