Comment on 4k is not 2160p - heard it here first!

• CybranM@kbin.social ⁨2⁩ ⁨years⁩ ago

  Calling 3840x2160 "4k" makes sense since 3840 is so close.
  On a different note sometimes I've heard people call 2560x1440 for "2k" but neither 2560 nor 1440p are close to 2k so that makes little sense to me

    1920x1080p is closer to 2K if anything.

      yep Full HD is a 2K resolution https://en.wikipedia.org/wiki/2K_resolution

    I think people call 1440p 2k because they know 4k exists and associate 1080p with 1k.

  The logic of some people goes that anything under 4000 horizontal pixels is not “real” 4k. But as mentioned, I don’t care and also call 3840x2160 “4k” simply because it’s shorter than “2160p”.

  4K is definitely a formal standard

    Ok, can you formally define it or link me to it?

    And I don’t want a definition for “4k DCI” or “4k UHD” … just a formally accepted definition of “4k” (in the context of a display resolution). We can all agree that it colloquially means the number 4000, I hope.

      There is not one definition, if you hear “4K” you can use the context of the conversation to determine if they’re talking about the consumer 4K UHD format or cinematic 4K, neither of which have a vertical resolution of exactly 4000px. UHD standards are maintained by ITU DCI standards were developed by the DCI group and are now maintained by SMPTE

        I agree. But then it’s not a formal standard.

  Huh TIL
  I thought it was because 4k has 4x the pixel count of 1080p
