The reason why 2K is more efficient and more popular is that it’s a great resolution for video. But it’s not the most efficient and it’s not the most popular. Yes, 4K resolution comes with additional expense in terms of storage.
As with most things that go beyond the ability of a single unit, there are many different ways to achieve a 4K resolution. For example, you could take a picture at 240 x 48,000, and the display could scan in at 454 by 362. The resolution can be significantly improved by decreasing the size of the image to achieve 454 by 360. For example, here’s a video that was shot at 1440p and 4K resolution:
The other advantage of 1440p vs. 2K resolution is that you can use both displays on mobile devices and not have your display get too hot. The issue with 1440p screens is that they get hot, but not so hot that your phone might turn off. When you switch from 1440p to 2K or 4K, your battery life will also improve. When a phone is in hot standby mode to conserve battery life, it uses the heat generated by the display and is still consuming power, but this reduces the amount that’s used to save the battery. On the other hand, if the display stays lit and continues to perform very well, you can leave it as it is, and not switch away from your phone, for a higher resolution.
One reason why people prefer 4K resolution is that you’re getting more pixels than you get with 2K or 1080p resolution, which give viewers something to look at, something more that’s more beautiful. They would say, “Wow, there’s more to look at here than what we got with 1080p.”
The question I have to ask, “Are 4K and 2K resolutions the same?” The short answer is no, but I would say they are very similar in efficiency. I know of no one that’s using 4K or 2K resolutions on the same TV, so that’s no problem, though if you’re watching a movie like “Loving” on a 1080p screen and you want to zoom in, you’d want to move to a 3D experience. As for TVs today, even if they’re 4K or 2K, they still tend to use a smaller 2-D screen size, so to speak.
It’s not like there’s some sort of magic magic number that all TVs are or
