That would only be true if the screen was really refreshed at that
frequency, which it isn't.
And when connected to a PC or an external device, it only accepts a
24, 50 or 60Hz signal.
The 600Hz has little to do with the refresh rate, and all to do with
motion compensation. Pure marketing gimmick term.
So in the end, they make absolutely no difference whatsoever to the
quality of display of connected say to a myth front end.
Btw, 25 fps would have no issue on a 100Hz screen.
