Is there a way to use this to fix my display? Sorry for creating an issue, I saw a commit about resizing window, my goal is to limit my screen.

The concept is:

I create a "virtual" screen (a dummy) in software with my undamaged 2483 x 1357 resolution.

My Mac's OS will see this as its only display/main screen. -> This is available. 

I want to "stream" the contents of my screen on this virtual screen. -> Available

This is an interesting use case I figured out of virtual display but I am unsure how possible it is.

Had the same problem with my external display, used Betterdisplay to do this.
