• If 2K is 1440p and 4K is 2160p.Then what is 1K and 3K?

Mathematically,4K is 2160p so 2K is supposed to be 1080p but it isn't.1080p is full HD and 2K is 1440p.So what are 1K and 3K resolutions? I've been wondering about this for a long time.It'd be great if you guys can figure it out.
Show us your "maths" first
1080p IS 2K because it more or less has a width of 2000px (1920).
1080 is 2K though, and 1K is 560. 3Ks would be 1680?
2K is not 1440p. It's 2048x1152 and 4K is 4096x2304. 3K and 1K aren't standard resolutions. 3K would be 3072x1728 however.
Mathematically speaking, 4K UHD (Ultra High Definition) is 3840x2160 because the number of pixels it has in total is four times that of 1920x1080. 1920x1080 = 2,073,600 pixels 3840x2160 = 8,294,400 pixels 8,294,400 divided by 2,073,600 is 4. This is because a 4K UHD monitor is, at its most basic level, four 1080p screens in a 2x2 grid formation with no bezel in between them. Each one of those screens is synced/positioned perfectly with each other to create a single, seamless image. A 2K UHD display would have to display 4,147,200 pixels, which is twice the number of pixels that a 1080p display has. However, no common display resolution currently contains that number of pixels. So it just jumps from 1080p straight to 4K UHD, and then the next tier up is 8K UHD (7680x4320).
1K, 2K, and 3K are not set-in-stone resolutions. The idea is that you would ideally go for 1K, 2K, or 3K pixels in the highest number in your aspect ratio (16:9, 16:10, etc.) while adhearing to hardware or software limitations. These xK resolutions vary, but generally stay around their target resolution. [B]I.E.[/B]: 3K resolutions tend to stay near 3000 pixels in width/height so the number fluctuates between certain multiples of the higher aspect ratio number around the target number. Such as 16 * 185 = 2960 which is close enough to 3000 to be "3K." [editline]23rd April 2014[/editline] Also ^ this guy is also right about there being a certain number of pixels.
