The mobile screen didn't displayed when switching from multiple monitors to my laptop's monitor.

As usual, I connect my laptop with two PC monitors, the mobile screen is displayed. However, when I disconnected my laptop with the two PC monitors, the mobile screen didn't display. 

Whenever, I click "Show Mobile Screen", the mobile screen just splashed and the button "Show Mobile Screen" changed to "Hide Mobile Screen" but the mobile screen didn't show on my laptop.

Is threre any way to make it work as normal?

I have restarted my laptop but it didn't help.

Thank you.
