The number vs. arrow direction on this sticker...

ChaoticNeutralCzech@lemmy.ml to Mildly Infuriating@lemmy.world – 44 points –

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: 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.
