If I was conspiratorial I would say that 4K was normalized as the next step above 1440p in order to create a demand for many generations of new graphics cards. Because it was introduced long before there was hardware able to use it without serious compromises. (I don’t actually think it’s a conspiracy though.)
For comparison, 1440p has 78% more pixels than 1080p. That’s quite a jump in pixel density and required performance.
4K has 125% more pixels than 1440p (300% more than 1080p). The step up is massive, and the additional performance required is as well.
Now there is a resolution that we are missing in between them. 3200x1800 is the natural next step above 1440p*. At 56% more pixels it would be a nice improvement, without an outrageous jump in performance. But it doesn’t exist outside of a few laptops for some reason.
*All these resolutions are multiples of 640x360. 720p is 2x, 1080p is 3x, 1440p is 4x, and 4K is 6x. 1800p is the missing 5x.
4K is an outrageously high resolution.
