How can I set up my development environment so my monitor acts as the main display when running my game on multiple screens?

Setting Up Your Development Environment for Multi-Screen Gaming

Primary Display Configuration in Unity

To ensure your game always runs on your main monitor when using multiple screens in Unity, follow these steps:

• Unity Display Settings: Open Unity and go to Edit > Project Settings > Player. Under the ‘Resolution and Presentation’ section, ensure that ‘Default Screen Width’ and ‘Default Screen Height’ match the resolution of your main display.
• Scripting for Display Control: You can use the Display.displays API to control which monitor the game starts on. Here’s an example script:

using UnityEngine;
public class MainDisplaySetup : MonoBehaviour {
    void Start() {
        for (int i = 0; i < Display.displays.Length; i++) {
            Display.displays[i].Activate();
        }
        Display.displays[0].SetParams(Screen.width, Screen.height, 0, 0); // Sets main display as primary
    }
}

• OS-Level Configuration: On your operating system, ensure your desired main monitor is set as the primary display in the display settings. This can usually be configured in the display settings of Windows, macOS, or your Linux distribution.

Additional Tips for Multi-Monitor Setup

• Development Environment Customization: Customize your Unity editor to reflect your multi-monitor setup. You can drag panels and tabs to different screens to maximize your workflow efficiency.
• Monitor Arrangement Techniques: Physically arrange your monitors to match their logical arrangement in your OS settings. This helps minimize confusion and ensures a seamless workflow.
