Get monitor that the game is running on

Is there a way to determine what monitor the game is currently running on (i.e. left or right)? I need to detect if the game window was moved to a different monitor.
I don't see anything in https://docs.unity3d.com/ScriptReference/Screen.html regarding an ID#.

Thanks.

 

I don't think there's a unity API that can do that due to the amorphous nature of what 'left' and 'right' mean when talking about monitors. You can probably figure it out using native win32 methods, however.

Windows does so much internal magic you basically cannot know. It's a huge nuisance. Best thing I've been able to do is make dropdowns that allow you to retarget cameras to different display id's and pray that windows populates them consistently.

 

From version 2021.2.15 there is new functionality regarding this and you can use this to get the index of the screen your app is on:

Code (CSharp):

1.     public int GetCurrentDisplayNumber()
2.     {
3.         List<DisplayInfo> displayLayout = new List<DisplayInfo>();
4.         Screen.GetDisplayLayout(displayLayout);
5.         return displayLayout.IndexOf(Screen.mainWindowDisplayInfo);
6.     }
7.  

 

Bump. Is there any way to do this before v2021.2.2?

I'm locked in on v2021.1 is the only problem.
