Thanks for your answer.
Probably this is what the Q10Pro is outputting, but, FOR SURE, the tv (Panasonic TX-50DXU701 has only 8-bit display. This is the display tech specs.
It's not bad, it was all I could afford.
Right now I am watching some series, 720p, and is showing 8 bit 4:4:4: 24, and 4:4:4.So it is not always the same, it is a function of the playback film.
The first, Hobbit, was a direct rip of a bluray, like 38GB (huge), probably that was why the 4:4:$: 12bit quality.
Cheers.
Edit: Later, I played again Hobbit, and was only 8 bit 4:4:4:.
Now I understand:
setting up Q10Pro, in settings/display to 2160p-30Hz playback, and using your autoFMTswitch_1.3.9.2, the playback of the movie is 1080p, 24hz, 4:4:4:12bit.
after I removed autoFMTswitch_1.3.9.2, under the same diplay sting of 21`60p-30Hz, the same movie playback is 2160p-24Hz, and 4:4:4: 8-bit only.
So, your framerate switch is actually helping augment to 4:4:4:12bit signal, but only 1080p, so the tv does the upscaling.
Without your framerate switch, the playback is 2160p but 4:4:4: 8-nit only.
I still fight to understand what's best for the eye....
