Hello,
I am interested in possible solution of my problem.
I have dual monitors set as extended most of the time but I when I finnish some work I turn one monitor off and use just the second one. Still the windows stay on the second monitor and also the mouse cursor is leaking to the offline monitor. Everytime I have to press win+p and set it just to PC scree only.

Is it possible to make it automatic when I turn monitor off displayfusion somehow set PC screen only for me and again when I turn the second monitor on displayfusion sets extended.

Thank you!
