[SOLVED] Turn the display backlight off

I dont know yet if this is even possible with this kind of display, but could you turn off the backlight completely?

it appears that X is going dark after some time, but the backlight keeps beeing powered on.
I think in a dark room this is still too much light pollution, let alone the quite useless powerconsumption.

I know what you mean :frowning: This is not how we want it either.
It is a problem with these kind of displays. We have tried various ways but you cannot simply turn the backlit off as HestiaPi Classic did. There is a sort of handshaking that needs to be done again every time the backlit needs to turn on. We are looking for alternative displays which cost much-much more but this may be the only way.
