The HDMI Black level setting confuses me on my LG. When I set it to Low-- the screen gets darker/more contrasty. whereas when I set it to high it gets less constrasty. To me that means the Low = Limited mode, and High = Full mode, as High is trying to read past 16-235 for darks and lights it seems. At least, thats how it seems like its working to me.
Last time I checked it was:
Limited = Low
High = FULL
