How to find out total number of monitors

[rimmi2002]

Hi I am writing a script and I'd like it to behave differently based on the # on monitors attached. Is there a way to find this out by an Autoit command? Thanks.

Look at the _WinAPI_EnumDisplayMonitors() function, the top line returned gives you the count of monitors.

Also see _WinAPI_GetSystemMetrics()

#include <WinAPI.au3>
#include <WindowsConstants.au3>
#include <Array.au3>
; From https://www.autoitscript.com/forum/topic/134534-_desktopdimensions-details-about-the-primary-and-secondary-monitors/

Local $a[] = [_WinAPI_GetSystemMetrics($SM_CMONITORS), _ ; Number of monitors.
        _WinAPI_GetSystemMetrics($SM_CXSCREEN), _ ; Width or Primary monitor.
        _WinAPI_GetSystemMetrics($SM_CYSCREEN), _ ; Height or Primary monitor.
        _WinAPI_GetSystemMetrics($SM_CXVIRTUALSCREEN), _ ; Width of the Virtual screen.
        _WinAPI_GetSystemMetrics($SM_CYVIRTUALSCREEN)] ; Height of the Virtual screen.

ConsoleWrite("Number of monitors = " & _WinAPI_GetSystemMetrics($SM_CMONITORS) & @CRLF)
_ArrayDisplay($a)

Thanks for the help.

(a bit late but good information)
_WinAPI_GetSystemMetrics(80) gives you the number of active monitors

 

 

#NoTrayIcon
#include <WinAPI.au3>
$aDevice = _WinAPI_GetSystemMetrics(80)
if $adevice = 1 Then

... (enter your intended action here if one monitor is present)

EndIf
