    It still is.

    720 = HD 1080 = Full HD

    Then I think there’s UHD, before they start labelling them as shortened numbers like 8k

      Wut? No

      Update in italics: immediately after posting my comment I see we agree, I just missed it because I had expected a separator between the two formats. I’m going to let my comment be, because it can serve as a reference for others.

      1080p = 1920x1080 = “Full HD”
      720p = 1280x720 = “HD Ready”, or at least according to wikipedia https://en.wikipedia.org/wiki/Display_resolution_standards “HD”

      4K has to subtypes 4K UHD and DCI which is both 2160 lines, but UHD is 16:9= 3840 pixels wide, and DCI is slightly wider with 4096 pixel in a 256:135 format. But both are “4K”

        I think you should read your link again. It clearly says 720 is “HD”.

        “HD Ready” was a marketing term that was sometimes used for things that were both 720 and close to 720.

      Uhd is not 4k. Uhd is 3840x2160, 4k is 4096x2160. TV companies calling 2160P UHD is a scam.You can’t watch 4k on 2160p uhd, but you can watch 2160p on real 4k. All hollywood movies have to be rerendered or upscaled from a 2k (2048x1080) version to fit on a t v.

        Wikipedia:

        4K resolution is a horizontal display resolution of approximately 4,000 pixels. For digital cinematography, it is 4096 × 2160 (DCI 4K), typically with a 256:135 (1.9:1) aspect ratio; for digital television, it is 3840 × 2160 (4K UHD), typically with a 16:9 (1.78:1) aspect ratio.

        I think it’s fine. 160 px here and there is less than 5% difference.

        Honestly, I stopped trying to understand them after 1080.

        I’ve worked on broadcast for over a decade and up until recently is been almost exclusively 1080i that I’ve dealt with.
