Hi, This may be a noob question, but I have not found an answer on forums or otherwise. I have upgraded a few of my Photo Frames to use balenaDash. I have used the Backlight scheduler to turn off Pi 7" screen successfully. However I have a 2 other that use HDMI connected monitors. In the past I have used tvservice to make this happen. I cannot however find a way to do this on balenaDash.
Any help or pointing tin right direction will be much appreciated.
