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?

If 2K referred to the number of pixels, it would look like this:
FullHD is actually a little over 2M pixels.
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.
Yeah, and none of the 4k’s are 4k
https://en.m.wikipedia.org/wiki/2K_resolution
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.
Both get referred to as 2K. https://en.wikipedia.org/wiki/2K_resolution
I would prefer 2560×1440 to be called 2K5 but the industry is too comfortable with 2-letter resolutions now.
The Explain XKCD for this comic is gold.
