Why is 2160p video called 4K?
In: 4205
Because there are ~4,000 horizontal pixels. 4K resolution is 3840×2160, and calling it “3.84K” doesn’t sound as good.
The 2160 in “2160p” is the vertical pixel count.
**EDIT** because people keep replying to “correct” me:
3840×2160 is 4K UHD.
4096×2160 is 4K DCi.
Both are referred to as 4K.
This is also why “4K Is Four Times The Resolution Of 1080p!” is not correct.
**EDIT AGAIN** because I don’t know what y’all want.
Yes, 3840×2160 is four times more pixels than 1080p. But **4K is not,** because that resolution **isn’t all 4K can be.**
Furthermore, this was all referring to people saying it’s *called* 4K because it’s four times the resolution of 1080p, and even though 4K UDH _is_ four times the resolution of 1080p, **that is not why it is called 4K**. It is called 4K because **there are about 4,000 vertical pixels** in both definitions of 4K (i.e., 3840 and 4096).
