Nice! @ socd.
Here are all the switches, if needed:
Projector only
displayswitch /external
Monitor only
displayswitch /internal
Project and monitor both
displayswitch /extend
Monitor cloned
displayswitch /clone

When I plug in my external monitor, it automatically takes the "\\.\DISPLAY1" name away from my laptop. and sets the display to clone.
I want to be able to make my laptop (now calling itself "\\.\DISPLAY1") the primary display and extend to my external monitor ("\\.\DISPLAY1")
Can anyone help me achieve this? |

| I think you can do that in your video card control panel |

yes I can, but I have to do it every time I plug my monitor in, and I wanted AHK to speed up the task |

Hello,
I have a notebook, and when it is attached to the docking station at the office, I use a second monitor. Now I tried all the scripts in this thread, but none of them switch this secondary monitor on or off.
Using the very first script from this thread I get the message: "Error getting display attached status."
Using this one: | Code: | ; EnumDisplayDevices(Index [, ByRef Name, ByRef StateFlags ] )
;
; ... removed "documentation"
;
;/* 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)
text .= DeviceName " is a pseudo-device.`n"
}
MsgBox %text%
;*/
EnumDisplayDevices(Index, ByRef DeviceName, ByRef StateFlags="", ByRef DeviceKey="")
{
; DISPLAY_DEVICE DisplayDevice
VarSetCapacity(DisplayDevice, 424)
; lpDisplayDevice.cb := sizeof(DISPLAY_DEVICE)
NumPut(424, DisplayDevice, 0)
VarSetCapacity(DeviceName, 32, 0)
VarSetCapacity(DeviceKey, 128, 0)
; For consistency, clear StateFlags in case of failure.
StateFlags = 0
if ! DllCall("EnumDisplayDevices"
, "UInt", 0
, "UInt", Index-1
, "UInt", &DisplayDevice
, "UInt", 0)
return false
StateFlags := NumGet(DisplayDevice, 164)
DllCall("lstrcpynA", "Str", DeviceName, "UInt", &DisplayDevice+4, "int", 32)
DllCall("lstrcpynA", "Str", DeviceKey, "UInt", &DisplayDevice+296, "int", 128)
if (SubStr(DeviceKey,1,18)="\Registry\Machine\")
DeviceKey := SubStr(DeviceKey,19)
return true
}
|
I get a message box containing only the OK button.
Is there any possible solution to my problem out there?
Thanks,
ikarus |

| The Windows+P shortcut (on Win 7 at least) can be used to enable, disable, or set multiple monitors and projectors. |

It can be used as follows: | Code: | ; disable display 2
EnableDisplayDevice(2, false)
Sleep, 10000
; simultaneously enable display 2 and disable display 1
EnableDisplayDevice(2, true, true)
EnableDisplayDevice(1, false)
Sleep, 10000
; ensure both are enabled
EnableDisplayDevice(2, true, true)
EnableDisplayDevice(1) |
(Edit: corrected comment about device numbering and display settings.) |
Lexikos' code still works well... under AHK-Basic. Could anybody adopt it to AHK_L? I don't have any knowledge on DllCall, NumPut and VarSetCapacity.
Thanks in advance. |
