There is enough confusion between horizontal resolutions (2K, 4K etc.) and vertical ones (1080p, 2160p etc.). This is not helping; why even print a promotional sticker with a number of pixels smaller than what it should be?

    This confusion is likely local and exists inside your head only. 1080p has been known as full hd since the early days of dvd.

    2k and 4k does not refer to horizontal resolution but the number of pixels. 1080p is 2k

      But 2K and 4K do refer to the horizontal resolution. There’s more than one resolution that’s referred to as 2K, for example 2048 x 1080 DCI 2K, but also 1920 x 1080 full HD, since it’s also almost 2000 pixels wide. The total number of pixels is in the millions, not thousands.

      For 4K some common resolutions are 4096 x 2160 DCI 4K and 3840 x 2160 UHD, which both have a horizontal resolution of about 4000 pixels.

      I know the difference but there are lots of people who aren’t really savvy with video technology. I wouldn’t blame them for thinking that ［🢐 １０８０ 🢒］ is just barely better than 1024x768.

      2k and 4k does not refer to horizontal resolution but the number of pixels

      Nope. 1920×1080 is 2 073 600 pixels, which would be 2M. “2K” is the horizontal resolution (1920) rounded up. A screen with literally 2K pixels would be around 50×40, lower than the crappiest handheld consoles.
