Using `xset -dpms` indeed seems to fix the problem, however, the external display does not become blank. This is not healthy for the display's matrice - in the manual, they recommend to not keep the same image on the screen for too long.
Anyone know a workaround similar to `xset -dpms` but with external screen blanking?
