Projector Tricks in Windows 7

Posted in Windows 7 by Steve Sinchak

In older versions of Windows using an external projector with your laptop can be a difficult task. It seems like every laptop has a different function key combination to enable output for a projector. In Windows 7 that has finally been improved. Now, all you have to do is hit the Windows Key + P and the projector menu will be displayed.

The on-screen display will allow you to:

  • Show Desktop only on Computer
  • Duplicate Desktop on Projector
  • Extend Desktop to Projector
  • Show Desktop only on projector

If you don’t like keyboard shortcuts you can also create a desktop or taskbar shortcut to the projector menu. To do that, create a shortcut to "C:\Windows\System32\DisplaySwitch.exe".

Displayswitch.exe also has command line parameters that allow you to create a shortcut that will set a specific display mode.  

  • /internal
  • /clone
  • /extend
  • /external
If you wanted to create a shortcut that would turn off your external monitor then point a shortcut to "C:\windows\system32\displayswitch.exe /internal".
