Screen just display black (backlight on), monitor does not go into Standby

[c4vem4n]

Hello

I am new to the Pi-computers and was searching in the forum and the internet if i can find a solution to my problem but can't find any. So maybe you can help me.

 

I'm using a BananaPi m1 with a 7" HDMI touch screen running armbian with GUI.

Its ruuning fine with one little issue:

When the system is temporary unused the screen should turn off/go to standby after a few minutes to save enery.

The screensaver setting is working but with my BananaPi the scree just goe black but does not tunr off.

 

If I connect the same screen to a Windows Computer the screenturns of with te screen saver.

 

Any ideas what I can do to get the monitor to turn off the backlight/ go to standby?

 

 

Thanks
