Automatic desktop extend when second screen is turned on/off

Are you aware of this shortcut to control display extension? This solution is not as simple as turning your second screen on and off and having it 'just work', but it is much easier than working with the resolution settings dialog.

Hold WIN and press P repeatedly to cycle through the following display options:

• Computer only displays your desktop only on your primary screen.
• Duplicate replicates your desktop on your primary screen and secondary screen.
• Extend displays an extended desktop across two screens.
• Projector only displays your desktop only on your secondary screen.

To enable an extended display quickly after turning on your second screen, hold WIN and press P until Extend is the highlighted option:

Release the keys to enable an extended display across your two screens.

To return to a single-screen display, hold WIN and press P until Computer only is the highlighted option. Release the keys to disable the extended display.
