I also suggested these additions and changes:

These are the actual USA refresh rates
Commonly referred to as 30Hz and 60Hz.

To insure stutter free playback these refresh rates should be used instead of 30 Hz and 60Hz:

USA Frame refresh rates
720p 59.94Hz
1080i 29.97Hz
1080p 59.94Hz
Blu-ray 23.976Hz

Als0 these selection should be made available under video selections.
They are very useful for proper setup and may vary from system to system.
Some systems may need to differ from ideal in a Home Theater System.
This will allow user to tweak for Best result.

RGB Studio (Limited RGB) would be great. DVDs and Blu-Rays are encoded in studio level (16 – 235, limited). every android box i've tried crushes blacks badly and blooms the whites because they output RGB Full ( 0-255).

you can really see the difference when playing same video file on ps3/ps4 versus android box. ps3/ps4 has RGB limited setting, which 99 percent of tv's display. on android box deep blacks and whites have no detail but ps3 / ps4 displays detail. turning up brightness helps but washes the picture out

RGB Full ( 0-255) is for computer monitors, phones, tablets etc. KODI for windows has (16-235) limited in video options. it would be nice for android to.

maybe it is not possible for android box to do this though
