"K" Monitors

[othertomperson]

Read my other post above. (#28) The consumer standpoint on the resolutions is not the same as the actual ranges.

 

Yeah but the "consumer standpoint" is wrong. I don't see the sense in arguing which is more or less wrong -- they're all wrong. Since actual 2K is still 1080p in the sense that it has 1080 vertical pixels, I think it makes more sense to define 1080p as 2K for the same reason that 2160p was defined as 4K. That doesn't make that "right", and it doesn't make 1440p 2K either. But whatever.

 

Edit: I should clarify, I'm using "define" in the mathematical sense, we're defining a variable to mean... rather than "this is the dictionary definition of" sense.

4K is commonly mistaken for UHD.

 

see, their is your mistake. 4K is not mistaken for UHD.

4K UHD is an actual format defined by the CEA.

DCI 4K is defined (what a surprise) by the DCI as 4096x2160 @ 24Hz

let's clarfiy that by "actual 2K" you are refering to DCI definition of 2K.

And although all of the 2K DCI compliant products have to be able to playback material of a resolution of 2048x1080 at 24 and 48Hz, you will have a hard time finding an "2K" movie that has 1080 vertical pixels

Again the DCI has nothing to do with consumer electronics (and we are talking about consumers electronics here)

Consumer electronics companies are misappropriating an existing standard to mean something unrelated, hence the source of confusion and this entire discussion. It's irrelevant that there are no 1080p 2k movies.

consumer electronics companies are marketing their products with terms they agreed upon.

2k=1080p... (1920 x1080; 1920=~2K)

Nein

[PerfectTemplar]

It's the amount of times past 1080p.

No it isn't. 8K is not 8x 1080p.

[NeatSquidYT]

Oh ok, then explain me why here 1920x1080 monitors are sold as 2K...

Oh, damn. Apparently 1440p is 2.5k

 

sorry brah

I would love it if I could just get a straight answer. It means the amount of pixels, thank you everyone for being "so" helpful.

The "K" terms are a shorthand that is used for resolutions with approximately that many pixels horizontally (2K resolutions are ~2000 pixels horizontally, 4K ~4000 pixels, etc.) They don't mean a specific resolution, they're just terms for the general category of resolutions with that many horizontal pixels.

 

Let's leave aside technical definitions and industry standards, the context of the question is about what people mean when they say 2K, 4K etc. in the normal consumer space. In this case, 2K is used to refer to 1920x1080 (a.k.a. 1080p or FHD) and 4K is used to refer to 3840x2160 (also 2160p or UHD).

 

2.5K is used for 2560x1440, 3K has been used to refer to both 2880x1620 and 3200x1800, and 5K is 5120x2880.

 

Again though, those are just the common consumer usage, when a normal person says "4K" in casual conversation you can assume they are talking about 3840x2160, but 4K isn't strictly defined as that. It's a blanket term that can describe any number of resolutions, such as 4096x2160.

Here is a chart I made hope this helps

 

Edit: As shown in the chart 4K means 4 times the pixel count of 1080P

4K means 4000, as in 4000(ish) pixels horizontally. It doesn't mean 4x 1080p, just like 8K doesn't mean 8x 1080p.

Oh ok, I thought it is based on pixel count which I thought was strange as 8K is 16 times the pixel count of 1080P (as shown in highlighted)

2k isn't really a measure used. its suposed to mean 2000 horizontal pixels. mobile phones with 2k displays are branded quad HD. as its 4 times 1024x768.

most companies poorly advertise 4k. ultra HD (UHD) and 4k are actually 2 different resolutions.

UHD is 3840x2160 where as 4k is 4096x2160.

but some companies use one and the same. my monitor is branded as a 4k UHD 4kx2k when really its 3840x2160.

basically in simple terms pc monitors rough go:

1024x768

1280x720

1440x900

1920x1080

2160x1440

3480x2400

3840x2160

4096x2160

theres a few in between but not vastly common. 1080p is currently the standard, followed by 1440p but 4k is slowly creeping in.

As I said above, these terms don't have strict definitions, they are categories. 4K refers to either 3840x2160 or 4096x2160. If you want to be specific, you say 4K UHD or DCI 4K. There are more 4K resolutions than that (Academy 4K for example), it's not just those two.
