4K doesn’t support everything below. Some newer displays got rid of 240p support and would show nothing, it would say no signal.Ofcourse, a 4k tv runs everything below 4k and a 144hz monitor runs everything below 144hz. I really don't get your point ?
Pal won’t run on NTSC CRT’s. You won’t see anything properly unless you get a video converter. So no having a higher Hz doesn’t support everything below properly unless it’s a multi system TV that does support it.I did not say that. Read again. Your argument doesn't even make sense. It's always support up to and everything below. That's basic knowledge. What are you trying to get at ? Is it that ur trying to pull something out of context just to win a bullshit argument that doesn't even make sense ?
It does make sense because 24fps movies has to do 3:2 pull down to be displayed on a 60hz display properly. 60hz can’t display 24fps properly or it will get out of sync. It has to be a 120hz display or a multiple of 24 to display it properly without judder. So it doesn’t support everything below correctly and has to go through tv processing.
