Question

Just curious how this is working. Does it fall back to a software brightness fix in case it isn't possible over HDMI? Is there a way to know which mode it may be operating in?

I ask this because the quality of greys looks a bit different and while I am able to reduce brightness I am not able to change volume, which makes me wonder if it's using CEC kind of tech or not.

The LG C1 TV does not support DDC so software brightness used (the app changes the gamma table to adjust brightness).
