When we want to change the display setting, we can use the display setting UI.
But besides UI, can I directly change the setting in the registry so that I can programmatically do it?
For instance, I want to switch between "Duplicate these displays" and "Show desktop only on 1" via code.
How could I do so?

It is possible to create a batch file that will read a key in the registry, and if its 1, make it 0, else it will make it 1. I don't know that there is a registry key for this though. – soandos – 2011-12-14T06:38:52.037
Not sure about registry, but this code project article shows how to change display settings programmatically.
