It doesnt stand for a specific multiple like 960. See also 4K displays with 4096 pixels, 3K laptops with 3072×1920, 3000×2000, and 2880×1620 displays, Apple's 6K 6016×3384 display, etc. It doesn't mean a specific multiple of anything, just anything approximately 6000 (or whatever number).

Line 214: All standard HD resolutions share a {{ratio\|16\|9}} aspect ratio, although some derived resolutions with smaller or larger ratios also exist, e.g. {{ratio\|4\|3}} and {{ratio\|64\|27}}, respectively. Most of the narrower resolutions are only used for storing, not for displaying videos, while the wider resolutions are often available as physical displays. YouTube, for instance, recommends users upload videos in a 16:9 format with 240, 360, 480 (SD), 720, 1080 (HD), 1440, 2160 (4K) or 4320 (8K) lines.<ref name="YouTube">{{cite web\|url=https://support.google.com/youtube/answer/6375112\|publisher=Google\|website=YouTube Help\|title=Video resolution & aspect ratios\| access-date = 2024-05-04}}</ref> While the monikers for those resolutions originally all used a letter prefix with "HD" for the multiplier, and possibly a "+" suffix for intermediate or taller formats, the newer, larger formats tend to be used with "K" notation for thousands of pixels of horizontal resolution ~~(actually: multiples of 960)~~, but may be disambiguated by a system qualifier that includes "HD", e.g. "8K UHD" instead of just "8K". === {{resx\|640\|360}} (nHD) {{anchor\|640x360\|640 × 360\|nHD\|NHD}} === Line 364: [[DisplayPort]] version 1.3 added support for 5K at 60{{nbsp}}Hz over a single cable, whereas version 1.2 was only capable of 5K at 30{{nbsp}}Hz.
