It is an LG TV. I am using it to make a smart mirror that I have outfitted with a motion sensor, so I want the display to turn off after ten minutes of inactivity and turn on when it senses motion. Is there an xset command that I can use to do the equivalent of turning the brightness all the way down that doesn't shut down power to the display? If I can call such a command from my mirror app, that's what I'm looking for. Again, xrandr --output HDMI-1 --brightness 0 does precisely that but I can only get it working on the RPi 3.
