@jojopi, Thanks for the suggestion about xset dpms force standby, but unfortunately that shut the power to the screen, which caused my TV to display the "No Signal" screen. The only thing that I've tried that works is: xrandr --output HDMI-1 --brightness 0, but that only works on the RPi 3, and I really want to use a RPi 4 or RPi 5 for my project.
