damn. then it doesnt work for me :/
just to be sure. i got this in a new .ahk and i press: LWin+*, LWin+\ (on Numpad)
Code:
#NoEnv ; Recommended for performance and compatibility with future AutoHotkey releases.
#+NumpadMult::EnableDisplayDevice("\\.\DISPLAY1", -1)
#+NumpadDiv::EnableDisplayDevice("\\.\DISPLAY2", -1)
; EnumDisplayDevices(Index [, ByRef Name, ByRef StateFlags ] )
;
; Index: One-based index of device to get info for.
; DeviceName: [out] The name of the device.
; StateFlags: [out] Any reasonable combination of the following flags:
; 0x00000001 DISPLAY_DEVICE_ATTACHED_TO_DESKTOP
; 0x00000004 DISPLAY_DEVICE_PRIMARY_DEVICE
; 0x00000008 DISPLAY_DEVICE_MIRRORING_DRIVER
; DeviceKey: [out] Path to the device's registry key relative to HKEY_LOCAL_MACHINE.
;
; Returns true if the display device exists, otherwise false.
;
/* Example 1 (requires EnableDisplayDevice()):
SecondaryDevice =
count = 0
Loop {
if ! EnumDisplayDevices(A_Index, DeviceName, StateFlags)
break
if !(StateFlags & 8) ; not a pseudo-device
if (++count = 2) ; second device
break
}
if DeviceName
EnableDisplayDevice(DeviceName, -1) ; toggle
*/
/* Example 2:
Loop {
if ! EnumDisplayDevices(A_Index, DeviceName, StateFlags)
break
if (StateFlags & 4)
text .= DeviceName " is the primary display device.`n"
else if (StateFlags & 1)
text .= "The desktop extends onto " DeviceName ".`n"
if (StateFlags & 8)

}
