1080p/24 - The 24 is for film, all cinematography is hot at 24 frames per second.
For 50Mhz it is almost doubled, and 60Mhz padded a little more.
You could say that accepting 1080p/24 is better, however, it accepts, not displays. It then has to 're-process' to 1080i...
Hopefully somebody with much more knowledge on this can help you further.
