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
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.
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:
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.
The Explain XKCD for this comic is gold.
Yeah, and none of the 4k’s are 4k

dood. i never thought about that. maybe i should stop saying 4k
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.
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.
Yeah - like stated in the wiki article i linked. im not sure how I interpreted OP when reading the post again today. I didn’t notice the arrows part, and thats in the title.
