    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)

      All about aspect ratio, at a high aspect ratio 720 looks fine on a reasonably sized TV.

    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.

    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.

    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.

      No way, not even close. At least I can’t enjoy that anymore, I’m too much of a snob now… Are you watching on your phone or Laptop? That would make sense.

      However, 1080p h.265 can get you superior quality while saving space over 720p h.264.

      When I had to watch on my 65" UHD, it was 4-5GB/hour 1080p h.264 files at minimum. 8-10GB UHD h.265 minimum. When I rip BDs my 1080p stuff i rip and convert to h.265 and keep them around 5-6GB/hour (which is like 8-10 h.264 so a gain), and my UHD + DV/HDR stuff I rip are also about 12-15GB/hr… but I cut out all subtitles and alternate audio and keep stereo and multi channel English to help maximize that file size (for friends/family who don’t have surround or just use TV).

      Now that I’m on an 85" UHD, I kept most content the same (most shows don’t need UHD + DV or HDR) but on bigger theatrical stuff or content where I care, movies are closer to 20-22GB/hour for maximum enjoyment. It makes a very big difference when viewing lower bitrate vs higher bitrate! Way less banding, pixelation, and offers smoother playback in higher motion scenes. Plus, audio plays a huge part in immersion!

      Not everyone has the space though, for that content, so I get it. But treat yourself occasionally and watch something hi res with quality audio!

    i still go for 720 all the time because at a certain resolution, you’re just starting to see the pimples, at not extra benefit.

        Why is screen size important in this context? Sure, my TV is much bigger than my phone, but it is also multiple meters away. Considering the part those screens take up of my field of view, I’d say my phone is ‘effectively bigger’ than my TV.
