What is 4K TV and Ultra HD? All you need to know about 4K

In its correct usage, true 4K refers to a resolution of 4096 x 2160, which was first introduced in digital cinemas. UHD refers to a resolution of 3840 x 2160, which is the resolution you actually get on the TVs you take home.

So technically, 4K is the wrong term for 3840 x 2160 displays and content, but it’s said so often that two terms are interchangeable.
