"When most (all?) TV panels and their image processing run natively at 60 Hz, and all these widgets also output at 60 Hz... Just let one device do the fps resampling."
No they don't. Many run at 100Hz, 200Hz, 300HZ, and 400Hz as a quick hunt round panel specs tell me.
If your panel is native 60Hz, it's likely a fairly crap one.
Don't forget the majority of the world uses PAL or SECAM based solutions and that most of the world also uses 50Hz AC mains power.
