“Étendre mon bureau Windows sur ce moniteur” par programmation

Une première solution possible est... par le biais de l'interface graphique (mais sans interaction de l'utilisateur)

VB script (également décrit ici mais dans Autoit langue):

Option Explicit
Dim WshShell, Dummy, Splash

On Error Resume Next

Set WshShell = WScript.CreateObject("WScript.Shell")

'Main
Call DoIt
WScript.Quit

Sub DoIt
wshshell.Run("%systemroot%\system32\control.exe desk.cpl,@0,3")

' Give Display Properties time to load
WScript.Sleep 1000
WshShell.SendKeys "2"
WScript.Sleep 10
WshShell.SendKeys "%E"
WScript.Sleep 500
WshShell.SendKeys "%A"
WshShell.SendKeys "{TAB}"
WshShell.SendKeys "{TAB}"
WshShell.SendKeys "{TAB}"
WshShell.SendKeys "{TAB}"
WshShell.SendKeys "{TAB}"
WshShell.SendKeys "{TAB}"
WshShell.SendKeys "{TAB}"
WshShell.SendKeys "{TAB}"
WshShell.SendKeys "{TAB}"
WshShell.SendKeys "{TAB}"
WshShell.SendKeys "{ENTER}"
End Sub 'DoIt

En Autoit, qui serait:

;
; — toggle-screen.au3
;

; exec cpanel app `display settings`
Run(”C:\WINDOWS\system32\control.exe desk.cpl,@0,3?”)

; wait for window to be active
WinWaitActive(”Display Settings”)

; select 2nd display
Send(”{TAB}”)
Send(”{DOWN}”)

; work back to the ‘extend desktop’ control
Send(”+{TAB}”)
Send(”+{TAB}”)
Send(”+{TAB}”)
Send(”+{TAB}”)
Send(”+{TAB}”)
Send(”+{TAB}”)
Send(”+{TAB}”)
Send(”+{TAB}”)
Send(”+{TAB}”)

; toggle ‘extend desktop’ control and apply
Send(”{SPACE}”)
Send(”{ENTER}”)

; wait for window to be active
WinWaitActive(”Display Settings”)

; accept
Send(”{TAB}”)
Send(”{ENTER}”)

;
; — E.O.F.

J'ai uniquement testé sur un ordinateur nouvellement installé. J'ai créé un un extrait ici si vous souhaitez apporter des modifications
