How to change the display at runtime.

Question

I read this. But simply changing "UnitySelectMonitor" Player Pref only works after restarting the game.

I have arrow buttons to let the user change to the previous or the next available monitor. Here is the code example for the next monitor button.

     public Resolution[] resolutions;
 
     public int curRes;
     public int curMonitor = 0;
     public int curWidth, curHeight;
     public bool curFullscreen = true;
 
 public void nextMonitor()
 {
         curMonitor++;
         //checking if there is another monitor
         if (curMonitor > Display.displays.Length - 1)
             curMonitor = 0;
         
         //setting PlayerPref
         PlayerPrefs.SetInt("UnitySelectMonitor", curMonitor);
         //calculating available resolutions
         resolutions = Screen.resolutions;
         curRes = resolutions.Length - 1;
         
         //sets the best resolution
         curWidth = resolutions[curRes].width;
         curHeight = resolutions[curRes].height;
         Screen.SetResolution(curWidth, curHeight, curFullscreen);
 }

Here are my PlayerSettings: alt text

 public void ChangeDisplay(Camera camera)
     {
         Camera cur = Camera.current;
         camera.targetDisplay = 0;
         cur.targetDisplay = 5;
     }

I use this code it is very simple!
It switches cameras displays
