Hello,

I have 2 monitors and a TV connected to the same PC

the 2 monitors are extended to each other. the TV is a duplicate for the second display.

I want (if possible) a Powershell or CMD script to do the next:

  • change the TV to duplicate the main screen without running any other interface (just script run and end without interaction of the user more than the double click ).
  • another script to get back the TV duplicating the second display

I wash someone help me, please.

    Hello there,

    This sort of operation is not directly accessible from PowerShell in the sense that there is no .NET interface to these settings. A lot of core OS stuff is unmanaged code that can only be manipulated via win32 API calls.

    Windows 7, 8 and 10 are supposed to come with a small program that does exactly this: displayswitch.exe

    displayswitch.exe /internal Disconnect projector (same as "Show only on 1" from the Display Properties dialog)

    displayswitch.exe /clone Duplicate screen

    displayswitch.exe /extend Extend screen

    displayswitch.exe /external Projector only (disconnect local) (same as "Show only on 2" from the Display Properties dialog)

    Hope this resolves your Query !!
