Just keep making things more complicated for no good reason.

     4K   4096 / 2160 = 1.8962962962962964
     5K   5120 / 2880 = 1.7777777777777777
     8K   7680 / 4320 = 1.7777777777777777
    10K  10328 / 7760 = 1.3309278350515463

Thanks a whole lot.

What most people call "4k" is 3840:2160 (typical 16:9 = 1.77… aspect ratio). At least that's the amount of pixels in most TVs/Monitors I've seen.

True. But for the consumers there is typically no 4k but UHD (3840 / 2160). This matches the 16/9 aspect ratio in other resolutions.

Consumer 4K is definitely 3840x2160. Its likely 10K is the same situation; there are multiple resolutions that fall under that banner, but the consumer version will be 1.77 aspect ratio.

Some of the articles speculate that 4k and 8k are what you'd expect, and that 5k and 10k have the same vertical resolution as 4/8 but a wider aspect ration (probably something closer to that current cinemas use) and that's where the extra pixels are going.

Basically they may not all be the same aspect ratio.
