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"

    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.
