Display.Activate

Description

Activates an external display. For example, a secondary monitor connected to the system.

Creates a window with screen width and screen height, and with the default refresh rate.

• The primary display is 0.
• Secondary displays are 1 to 7.

Make sure an external display is connected before you activate it.

This method works only on desktop platforms.

using UnityEngine;

public class Example : MonoBehaviour
{
    void Start()
    {
        // Check the number of monitors connected.
        if (Display.displays.Length > 1)
        {
            // Activate the display 1 (second monitor connected to the system).
            Display.displays[1].Activate();
        }
    }
}
