How to swap from duplicate display to multiple monitor in command line

Essentially I want to make a batch file that will, when executed, swap between two states. the first state would be a duplicate monitor setting, whereas the computer will display the same thing on two screens, while the other setting would be a new monitor, so you could see two different things on the two monitors. I don't know a command that could do this, but it should be possible. I tried looking it up, but could find nothing relevant.

As long as you're on Windows 7+ 

DisplaySwitch.exe /clone

will duplicate displays.

This will extend displays:

DisplaySwitch.exe /extend

Hope this helps.

Also you can use Win+P if you want a quick shortcut.

There is no general solution for this using batch-files. However Nvidia drivers do provide a option fore this, it may be possible that other manufacturers have similar documents. I however would not know because all machines I work with have Nvidia cards.

The documentation can be found here. As per nvidia documentation to set dual monitor mode would be:

rundll32.exe setview 1 dualview AA DA

And setting both views the same would be:

rundll32.exe NvCpl.dll,dtcfg setview 2 clone AA DA
