1080p looks fine on a 4K (2160p) screen especially if whatever you’re using to display it (be that your machine, receiver, or the TV itself in the case of “smart” TVs) is good at upscaling. Worse case scenario it looks the same as 1080p content looks on a TV of the same size, since 2160p is literally just 4x the pixels of 1080p.
1080p can look bad on a 1440p display though, since it doesn’t go evenly in and you’ll need good upscaling.
And that's why it's better to use 720p in the cases where you can't do native 1440p.
Yeah.
I was with family, on an RTX 2060 laptop and a nice TV. I fed it 1080P for the TV to upscale (since that's the only res it would take at 120HZ or something like that), and it looked good. Those TV ASICs are quite powerful these days.
