Screen.fullScreen

설명

Is the game running full-screen?

It is possible to toggle full-screen mode by changing this property:

using UnityEngine;

public class Example : MonoBehaviour
{
    void Start()
    {
        // Toggle fullscreen
        Screen.fullScreen = !Screen.fullScreen;
    }
}

A full-screen switch does not happen immediately; it will actually happen when the current frame is finished.
