Hi there. I am using a 7.9-inch Waveshare HDMI screen; is there a method to adjust the brightness of the screen other than using the switch provided on the back side of the screen…? Rpi4 + volumio + 7.9-inch HDMI screen is my configuration.

there is no SW control for the brightness, only the button at the back, so the answer is no.
