However, the numerical shorthand looks likely to stick. This is one reason why some brands prefer not to use the 4K label at all, sticking with Ultra HD or UHD instead. However while your local multiplex shows images in native 4096 x 2160 4K resolution, the new Ultra HD consumer format has a slightly lower resolution of 3840 x 2160. Technically, "Ultra High Definition" is actually a derivation of the 4K digital cinema standard.

We're talking about a similar jump in resolution as the one from SD (480 lines high) to HD (1080 lines high). For extra added fun, you also might hear this resolution referred to as 2160p. And before you ask, yes, the industry named 1080 resolution after image height, but named 4K after image width. It's called 4K because the images are around 4,000 pixels wide.
