    Uhd is not 4k. Uhd is 3840x2160, 4k is 4096x2160. TV companies calling 2160P UHD is a scam.You can’t watch 4k on 2160p uhd, but you can watch 2160p on real 4k. All hollywood movies have to be rerendered or upscaled from a 2k (2048x1080) version to fit on a t v.

      Wikipedia:

      4K resolution is a horizontal display resolution of approximately 4,000 pixels. For digital cinematography, it is 4096 × 2160 (DCI 4K), typically with a 256:135 (1.9:1) aspect ratio; for digital television, it is 3840 × 2160 (4K UHD), typically with a 16:9 (1.78:1) aspect ratio.

      I think it’s fine. 160 px here and there is less than 5% difference.

      Honestly, I stopped trying to understand them after 1080.

      I’ve worked on broadcast for over a decade and up until recently is been almost exclusively 1080i that I’ve dealt with.
