4K is a little odd

Resolutions have always been 'named' after their vertical size, right? Like how 1920x1080 is 1080p. Wouldn't that mean that 4k would be something more along the lines of 7680 x 4320? 4K is only 2160p, whereas 4K literally sounds like it's 4x bigger than 1080p to those who aren't knowledgeable.

Is this some kind of marketing ploy where the horizontal size is secretly the number companies care about now to make them seem more impressive, or was it simply a swanky name for the new resolutions? It kinda sounds like the former. :p
 
1920 from 1080 is referred to as 2k. The 4096 or 3840 horrizontal is whats referred to as 4k

The 4x 'bigger' bit means that 1080p fits into 4k exactly 4 times, something like that anyway as I understand it
 
Well to be fair 4K does have 4 times the pixels of 1080p.

I think the name originally came from 4K DCI which is commonly used in films, and since 2160p is pretty close to that standard, it was called that as well, although they're usually called 4K DCI and 4K UHD to keep the two seperate.

They should be separate as they are two different resolutions.

I am pretty sure 1080 is not 2k.

2560 x 1440 is called 2k

This is all wrong.

3840x2160 isn't 4K. 1920x1080 isn't 2K.

4K is 4096x2160. 2K is 2048x1080.

They are cinema projector resolutions.

3840x2160 is UHD, or 2160P.

2560x1440 is not 2K, and it never will be. Anyone who says it is is categorically wrong.

2560x1440 is QHD (quad HD, HD Being 1280x720) or 1440P.

1920x1080 is FHD (full HD) or 1080P.

It can be too (although I personally wouldnt as its much better), it goes by horizontal lines, just like there is more than 1 4k resolution.

There is more than 1 4K resolution, however they are all cinema resolutions, which are crops of 4K, for example movies filmed in ultra wide aspects.

There's 4096x1716, for example. There's also 3996x2160.

3840 isn't close enough to 4 thousand (which is what the K stands for) for it to actually fit into the 4K category.

But we also had DCI 2K along side 1080P and people didn't latch on to that and claim 1080P is 2K.
 
No one calls 1080p "2k" in the consumer world.

2560 is not 2k either.

4k as opposed to 2160p was adopted to make it sound massive compared to 1080p. Pure marketing bile.

2k, in whatever *******ised form it is used, is just regression to compare it against 4k.

edit: valid word that there. le sigh
