Running the game on a dual monitor system

VikShim

Hi everyone, my problem is: I have two monitors, 3840x2160 and 1920x1080. The 3840*2160 monitor is set as the main one in Windows OS, the editor opens and works on it, expanding to full screen. The game does not work so. The game does not start in full screen, but only as on the screenshot (I circled the borders of the game window with a red frame for clarity). At least in the editor, at least in the build (after export). Settings as in the documentation: Width - 3840 Height-2160 Mode-2d Aspect - Expand

MOST IMPORTANT - if I turn off the second monitor (which is 1920 * 1080), then everything is fine - the game starts in full screen mode. If the second monitor is connected - then only as in the screenshot.

Try the Window Placement options in the Editor Settings.

Thanks, I've tried different Window Placement settings. Also tried with code:

  var screen_size : Vector2 = Vector2()
             
 func _ready():
            screen_size = OS.get_screen_size()
    		print(screen_size)
	            	if OS.get_screen_size() != screen_size: 
	            		screen_size = OS.get_screen_size()
	            		OS.set_window_size(screen_size)

Nothing helped. The print shows that the engine sees the monitor resolution as 2560 * 1440. Although if i turn off the second monitor, then everything is fine. Engine 3.4.4. I downloaded Godot 4.7 Alpha for testing - there are no problems, the game is either in the editor or in a stand alone build in full screen mode. But in version 3.4 only when the second monitor is disabled.

You have to pass the monitor index to those functions (by default it uses the main screen).

Might be this.

Try 3.5beta5 to make sure the issue is resolved on your end :)

Also try enabling Allow Hidpi in the Project Settings.
