A pedantic breakdown of how monitor and video resolutions are named and why common shorthand labels like '2k' for 2560x1440 monitors are technically wrong. Covers the origins of the 'p' suffix (progressive scan, not pixel lines), the 'k' prefix as a metric unit, and why true 4k is DCI 4096-wide while consumer '4k' monitors are actually UltraHD at 3840x2160. Includes a reference table of common resolutions with their formal names, vertical labels, and horizontal labels.
