Change Camera.VerticalToHorizontalFieldOfView by script?

Question

I am testing a game with 3 projectors(multi monitor) with a final screen resolution 5760 x 1080. I want to change by code Camera>Fov Axis but I can't figure how, I got this error: "Member 'Camera.VerticalToHorizontalFieldOfView(float, float)' cannot be accessed with an instance reference; qualify it with a type name instead". I have tried this codes: `

 [SerializeField] Camera[] cams3;
 
 
  void Update()
         {          
 
             if (Input.GetKeyDown(KeyCode.End))
             {
                 ChangeFovAxis();
             }
         }
 void ChangeFovAxis() {
                 
                 var cam = Camera.main;
                 cam.VerticalToHorizontalFieldOfView(1, 1); // doesn't work same error from the loop below           
     
                 for (var i = 0; i < cams3.Length; i++)
                 {
                     cams3[i].VerticalToHorizontalFieldOfView(90, 1); // I need to change the 3 cams
                 }
                
                 Camera.VerticalToHorizontalFieldOfView(90, 1); // no error but nothing happens   
                
             }

Hi, If you want to change the field of view of your camera, you should do it like that:

your_camera.fieldOfView = desired_value;

VerticalToHorizontalFieldOfView is just a function that returns an horizontal FOV from a vertical FOV and an aspect ratio. And it should be called always from the class name,not from an instance.

Tks for the replay. Could you show a sample code how to call it? My main intention is to test on multimonitor( 5760 x 1080 -3 cams) if is better FOV Axis vertical or horizontal, which one has less distortion.
