how do I tell Mac Studio I have only ONE monitor?
I'm using a Benq 27" monitor with my Mac Studio computer. In Settings - Display It show's I have two Benq monitors when actually I only have one monitor. If I click on "Advanced" it shows "Push through the edge to connect to a nearby Mac or iPad. I cannot 'unclick', or clear, it.
What is happening is when I move my cursor to the right it goes off the screen. And seemingly gets lost. I have to drag left until it finally reappears.
How do I stop this?
at the bottom of the sidebar.
in the menu bar, click Display, then deselect your iPad from the list below “Mirror or extend to.”
> System Settings, then click Displays 
in the sidebar. (You may need to scroll down.)
