Okay.. so this time I used the following syntax between each color range setting and ensured the refresh rate changed by stopping/starting black bar video.

Code:

xrandr --output HDMI1 --off; xrandr --output HDMI1 --auto

The results are slightly different. It is still not making sense to me and no clear winner of a setting. The big question I have is why do I see black bars flashing below 16 when the driver is set to limited or passthrough? That is odd.

Code:

xrandr          kodi            lowest  banding         comments
