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?

    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.

      Nah

      They won’t know about 1024x768, but if they did they would understand that 1080 is barely better.

      Going from 1024 to 1920 horizontal also takes the aspect ratio from 3:4 to 16:9. so pixel density is barely better.

        If 2K referred to the number of pixels, it would look like this: Bliss 50×40=2000 This post 62×33=2046

        FullHD is actually a little over 2M pixels.

        takes the aspect ratio from 3:4 to 16:9. so pixel density is barely better

        What? Screen aspect ratio and pixel density are quite different things. Most FullHD TVs are widescreen and have pixel density below 36 ppi, and while high-DPI 4:3 screens are rare, they are not impossible in any way.

          The Explain XKCD for this comic is gold.
