Question How do I lock the mouse for Multi Display

I am making my character's camera move when the mouse moves left or right, (1st person) but I need to lock the mouse

I have the mouse locked and Invisible but when it moves out of the radius of my first monitor, it goes to the second or third

Code:

void Update()
{
if(Input.GetMouseButtonDown(0))
{
Cursor.lockState = CursorLockMode.Locked;
Cursor.visible = false;
}

if (Input.GetKeyDown(escapeKey))
{
Cursor.lockState = CursorLockMode.None;
Cursor.visible = true;
}
}

how can I get it so that it doesn't go to the second or third monitor unless I click Escape?

(also I am new to Unity)

 

I'm not sure you can, unless you control the bounds of the mouse values itself. But regardless from an indie game to full AAA title, if I move my mouse over to a "multiple" display setup, my mouse always goes into the next display.

I did to a point, just set settings in windows itself to turn off another display, if I only wanted to focus one(gaming), and that worked. So that leads me to believe that's a microsoft thing, not anything to do with unity itself.

Not sure though, haven't explored that further, myself..

 

when im playing any other game for me its fine, but just not in unity
