Screen.fullScreen

Description

Enables full-screen mode for the application.

Use this property to toggle full-screen mode. The following example toggles between the application's current full-screen mode and windowed mode.

using UnityEngine;

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

A full-screen switch doesn't happen immediately. The change takes effect when the current frame is finished.

Screen.fullScreen is a simplified, Boolean alternative to Screen.fullScreenMode. Setting it to true switches the application to the default full-screen mode configured in PlayerSettings.fullScreenMode. If no valid default is set, Unity uses FullScreenMode.FullScreenWindow. Setting it to false switches the application to FullScreenMode.Windowed. Reading the property returns true for full-screen modes. It returns false for FullScreenMode.Windowed, and might also return false for FullScreenMode.MaximizedWindow depending on the platform. To choose a specific full-screen mode, such as FullScreenMode.ExclusiveFullScreen or FullScreenMode.MaximizedWindow, use Screen.fullScreenMode instead. To change the resolution and full-screen mode together, use Screen.SetResolution.

Notes:

• Screen.fullScreen is read-only on iOS.
• When Stage Manager is enabled on iPadOS, the Screen.fullScreen remains true for the application built with full-screen display mode. The application maintains the full-screen resolution in supported orientations even when the Stage Manager scales the application.
