    It still is, but nobody cares anymore. At 16:9 1920x1080 is considered “Full High Definition,” and 3840x2160 (at minimum) is “Ultra High Definition,” at least in terms of their official marketing speak. The latter has mutated to include both 4K and 8K content somehow, apparently because the brainworms in the marketing department ran out of superlatives after “Ultra.”

      They should’ve hired tea industry execs. If the tea industry can come up with grades like “Special Finest Tippy Golden Flowery Orange Pekoe”, they can come up with something beyond Ultra High Definition.

      Maybe like this:

      • High Definition (HD)
      • Full High Definition (FHD)
      • Ultra High Definition (UHD)
      • Very Ultra High Definition (VUHD)
      • Special Very Ultra High Definition (SVUHD)
      • Full Special Very Ultra High Definition (FSVUHD or SVUHD1, both are acceptable)

      Not that these grades would only apply to displays that don’t support picture-in-picture or split screen. Displays with those features (“broken” displays) would use the following equivalent grades instead:

      • High Broken Definition (HBD)
      • Full High Broken Definition (FHBD)
      • Ultra High Broken Definition (UHBD)
      • Golden Ultra High Broken Definition (GUHBD)
      • Special Golden Ultra High Broken Definition (SGUHBD)
      • Full Special Golden Ultra High Broken Definition 1 (FSGUHBD1)

    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.

      And 1080p is Full HD.
      1440p is Quad HD.
      2160p/4K is Ultra HD.
      4320p/8K is also Ultra HD, for some bonus confusion.

        Whoa there: I said “I remember”, not that interlacing was good.

        And interlacing is only "good"for old video games that leveraged its weirdness for blending pixels.

        It is terrible as a video format.

        Remember when your dvd player had a “progressive scan” button?

    I remember TVs that were “HD compatible” which means they were like 520p, but could downscale an HD signal.

      Yeah I had one such 47" “HD Ready” plasma that did 848x480p. The pixels were so large you could see them but 720p content still looked good on it, and DVDs looked even better than they did on an HDTV due to the similar resolution of 720x480 that they output at. They were so much sharper on a display close to their native resolution.

    720p hits that sweet spot between file size and picture clarity so that’s my default preference for torrents.

      Yeah no. 720p is so low resolution that it no longer qualifies as HD IMO. I need 1080p minimum, 4K remux ideally. But what matters even more than resolution is codec and bitrate. I rather watch well-encoded 1080p video over a poorly-encoded 4K file.

    1280 × 720 was “HD ready”
    1920 × 1080 was “Full HD”

    I always thought “HD ready” was a bit of a marketing scam.

      I remember ”HD ready” as HDR, then years later HDR (high dynamic range) came a was very confused as to way a 1080p monitor was marked as HD Ready.

    Remember when 1080i was a thing? Now it’s all but dead beyond broadcast and cable TV (which is pretty much dead).

    People used to say that 720p was better because it had a higher vertical resolution at any given moment due to being progressive scan, but IMO 1080i looked sharper for the most part unless there was a lot of motion in the scene. The resolution was high enough that the flickering from the interlaced images didn’t bother me. So I usually went with 1080i over 720p. Sports titles and games with a lot of action were the only time when I would go with 720p.

    I don’t mind 720p at all, but I play a lot of old games and usually upscaling to 720p on PlayStation 2 games and stuff makes a tremendous difference.

    Anything older, CRT filters. Bloom and interlacing make games like Super Metroid very eerie.

        I haven’t seen that US standard of measurement yet! I didn’t know they do resolution as well.
