turn off display after inactivity

[Blindstealer]

May seem a trivial issue... but there is a way to turn off the screen after an inactivity period?

I am using a pine 64, latest rooted android installed (5.1.1) to run kodi.
On android only thing i can do is to exit kodi after a timeout, but there is no option to turn off monitor/system unlike kodi for pc.

So I am looking for an alternative way to turn off the hdmi signal from the pine64 so that the tv will shutdown after no source signal is detected.

should be in settings /display and it is called sleep timer for a period of time with no activity.

Thanks, already tried but didn't work. To make it work I had also to disable the option "Never sleep while charging" in Settings/Developer Options.

the app tasker probably has a setting to do this
