Automatic blank unused screen when using multiple screens
I have two screens, one horizontal and one vertical. Most of the time I use only one of them, sometimes the horizontal one and sometimes the vertical one.
I don't want to turn off the screen that is currently unused, mostly because it makes the multiple screens display disrupted.
For that I want an option to blank the unused screen, so after a chosen time of not using a screen, it will blank, and will wake up after moving the mouse to that screen (or moving a window to that screen and so on).
