to add to Mr video

PAL NTSC are old analogue broadcasting standards. The digital equivalent would be DVB-T and ATSC (there is also ISDB-t in other parts of the world and updated standards like DVB-t2 and ATSC 3.0...)

when PAL/NTSC were created they were dwefined to match the clock speed of the electric current wehich is 50 HZ in some places and 60Hz in onthers. that is why we tend to talk about 1080p60 or 1080p50 (or what ever other resolution)

In my experience most (if not all) modern A/v equipment for the 50 Hz market will also work with a 60 Hz signal but it is not as easy the other way around.

so like Mr.video said, look at the specs, but the important thing is to check if it supports 60Hz (not the resolutions, once you go HD/4k those are the same.)
