Disable screen that is being streamed to?

[hacker-DOM]

Hi

I would like to use a portion of my TV. I found I should change underscan in Displays -> Apple Silicone desn't support that -> use BetterDisplay -> create a virtual screen and stream it to the Tv.

The issue is the original screen still remains (in my Displays). It has the streamed content on it, so it is not accessible physically. But it can technically have windows. I have to remember to move all windows from it on startup and pray that no windows will ever appear there?

[Here is my 3-monitor layout. Virtual screen (streamed to Tv) is nice and center, but there is also the original screen to the left. This one is not viewable in the physical world]

For discussion

If you stream A to B 
streamed screen - A
streamed-to screen - B

Well, if it's not a main window, there is no much reason a window goes there. But you can specify a shortcut to quickly hide/unhide the stream in case one does or you want to peek what's under the stream. If you don't want the mouse to move over easily, you can move the original display to a corner of an other screen in the layout so the mouse has hard time traversing.
