Programmatically detecting and setting a specific monitor involves interacting with Unity\u2019s display settings.<\/p>\n<h3>Detecting Available Monitors<\/h3>\n<p>Unity provides the <code>Display<\/code> class which you can use to detect available monitors. Here\u2019s a simple way to list all connected monitors:<\/p>\n<pre><code>using UnityEngine;\n\nvoid ListDisplays() {\n    Debug.Log(\"Displays connected: \" + Display.displays.Length);\n    for (int i = 0; i &lt; Display.displays.Length; i++) {\n        Debug.Log(\"Display \" + i + \": \" + Display.displays[i].systemWidth + \"x\" + Display.displays[i].systemHeight);\n    }\n}<\/code><\/pre>\n<h3>Setting the Active Monitor<\/h3>\n<p>To set a specific monitor for your game, you must first activate additional displays and then select the desired display for rendering. Use the <code>Display.Activate<\/code> method:<\/p>\n<pre><code>void SetActiveDisplay(int displayIndex) {\n    if (displayIndex &lt; Display.displays.Length) {\n        Display.displays[displayIndex].Activate();\n    } else {\n        Debug.LogError(\"Invalid Display Index\");\n    }\n}<\/code><\/pre>\n<h3>Fullscreen and Windowed Mode<\/h3>\n<p>When your game launches, you may want it to run in fullscreen or windowed mode on the selected display. To switch between fullscreen and windowed modes while specifying the target display, configure:<\/p>\n<pre><code>Screen.SetResolution(width, height, FullScreenMode.FullScreenWindow, displayIndex);\n\/\/ or for windowed\nScreen.SetResolution(width, height, FullScreenMode.Windowed, displayIndex);<\/code><\/pre>\n<h3>Best Practices<\/h3>\n<ul>\n<li>Always check the number of displays available using <code>Display.displays.Length<\/code> before setting the display index to avoid out-of-range errors.<\/li>\n<li>Consider providing users with an in-game settings menu to choose the preferred monitor instead of hardcoding values, enhancing user flexibility.<\/li>\n<\/ul>\n","protected":false},"excerpt":{"rendered":"<p>Detecting and Setting a Specific Monitor in Unity Introduction With the rise of multi-monitor setups becoming more common in gaming environments, ensuring that your Unity game is displayed on the preferred screen can significantly enhance the user experience.
