[TESTING][S905(X)] 10bit/HDR/Dithering Test Builds & Discussion

  • My guess is that the echo command above sends a code to the HDMI TX subsystem to force HDMI output to 10 bit permanently.

    This has no massive downside for 8 bit content (there should be no visual difference between sending 8 bit content as 8 bit and sending it as 10 bit with 00s in the 2 least significant bits - unless your display dithers 8 bit content to 10 bit) but it does mean you can't tell 8- from 10-bit content from the output format.
