Change display settings on Workstation lock

[kirua]

Hi,

What I'm trying to do is to clone my display at workstation lock and switch to internal or external display at workstation unlock depending on the user.

I found a solution in another post : http://www.sevenforums.com/customization/94917-locked-computer-dual-monitor-3.html

The method 2 described seems to match my case but I can't manage to make it work... I created the tasks but nothing happen when I do Win+L...

Here is the description of the method :

METHOD 2: Scheduled Triggers
This workaround involves changing the display to duplicate screens when you lock your computer and changing it back to 2 screens when you unlock it.

To do this, we'll use task scheduler to run some command lines on a trigger. The triggers will be either unlock or locking of the computer.
%windir%\System32\DisplaySwitch.exe /extend to use two screens
%windir%\System32\DisplaySwitch.exe /clone to clone the screens
or we could also use
%windir%\System32\DisplaySwitch.exe /internal to use just one screen


So lets set this up
Create the First Task

1. Open the task scheduler by typing taskschd.msc into RUN or SEARCH and pressing ENTER
2. Right Click on Task Scheduler (Local) and select 'Create Task'
3. In the Create Task Window Type a Name for first the task (e.g. Single Display Lock)
4. Type in a description (E.g. This task is triggered when Windows is locked and changes the display to a single display)
5. Tick the 'Run with Highest Privilages' Box
6. Change the 'Configure for' drop down box to "Windows 7, Windows Server 2008 R2"
7. Select the TRIGGERS tab
8. Click NEW
9. In the Begin the Task Dropdown select "On workstation lock"
10. in The Advanced Settings Select the "Delay Task for" box and type 3 Seconds in the box beside it. NOTE: you may need to increase this if it doesn't work for you.
11. Click OK
12. Select the ACTIONS tab
13. Click NEW
14. In the Program/Script box type the following %windir%\System32\DisplaySwitch.exe
15. In the Add Arguments box type /clone
16. Click OK
17. Select the CONDITIONS tab
18. Click OK to save and exit the new task

Create the Second Task

1. Open the task scheduler by typing taskschd.msc into RUN or SEARCH and pressing ENTER
2. Right Click on Task Scheduler (Local) and select 'Create Task'
3. In the Create Task Window Type a Name for first the task (e.g. Extended Screen for Unlock)
4. Type in a description (E.g. This task is triggered when Windows is unlocked and extends the screen to two monitors)
5. Tick the 'Run with Highest Privilages' Box
6. Change the 'Configure for' drop down box to "Windows 7, Windows Server 2008 R2"
7. Select the TRIGGERS tab
8. Click NEW
9. In the Begin the Task Dropdown select "On workstation unlock"
10. in The Advanced Settings Select the "Delay Task for" box and type 3 Seconds in the box beside it. NOTE: you may need to increase this if it doesn't work for you.
11. Click OK
12. Select the ACTIONS tab
13. Click NEW
14. In the Program/Script box type the following %windir%\System32\DisplaySwitch.exe
15. In the Add Arguments box type /extend
16. Click OK
17. Select the CONDITIONS tab
18. Click OK to save exit the new task

It takes a few seconds to come up but it should work a-ok.
