@mcc framerates are just a suggestion, did you know that PAL and NTSC DVDs have slightly different runtimes because they slightly time-stretch the movie to fit 24 frames into PAL's 25
@mcc I assume most TVs can switch between 50 and 60 Hz just so it's easier to sell it in different regions. There are also variable refresh rate TVs now so you can theoretically play stuff at its native framerate. idk how good support is, it's meant for gaming
