Is there a way to enable/disable the backlight to save power on the PIM372 HDMI 8" IPS LCD Screen? ([https://shop.pimoroni.com/products/hdmi-8-lcd-screen-kit-1024x768](https://shop.pimoroni.com/products/hdmi-8-lcd-screen-kit-1024x768))?

I see that I can turn the screen on/off via the keypad, but I am looking for a way to only disable the backlight via a GPIO on a raspberry pi.

Or maybe there a way to provide a PWM signal from a raspberry pi to control the backlight strength so I can turn it off?

I’m back to answer my own question in case anyone else has a similar question. I can use these command below to turn the display off and back on. When the display turns off the backlight will turn off as well.

pi@raspberrypi:~ $ vcgencmd display\_power 0

display\_power=0

pi@raspberrypi:~ $ vcgencmd display\_power 1

display\_power=1
