To find out what HDMI connected display - Gamma and bit depth capabilities are registered with LE for use:
Forced RGB output is not needed unless you are getting Pink or Green screen on old Sony/Philips TV's.
This command gives me all options available within the last build.
S905 doesn't support 10 bit output. You can decode 10bit H.265 but they will be scaled to 8bit output.
Thanks, so choosing 444,10bit will not change anything at all.
