Turn off HDMI dispkay via "vcgencmd display_power 0"

[giuliomagnifico]

Hi,
I’m trying to simply turn off my HDMI display using vcgencmd display_power 0

root@DietPi:~# vcgencmd display_power 0
display_power=1
root@DietPI:~#

But as a reply I get “display_power=1”… I know that is “1/ON” I want to turn it off…

Any suggestion? Why the command doesn’t set the “0” state?

Thanks!

It’s not supported any more.

Great thanks, this worked!

At least on RPi, you can set headless mode via dietpi-config

Yes, this also saves some power!
