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.

              Greedy marketers just wanted to show a higher number… That’s why they switched from height to width, too.

                Isn’t 4k x4 the amount of fullHD pixels? Its like 4 fullHD screens stacked together, that’s how it was marketed and hence the name.

                  No, 1080p is 2K because its width is 1920 (close to 2000), 2160p is 4K (3840 px wide), 4320p is 8K (7680 px wide). It’s not 1K, 4K and 16K.

                    2K is 2560x1440p though, not 1080, make a quick google search and you’ll see it. It’s roughly double the amount of pixels of fullHD.
