Rotate the whole screen

[daniel_bingamon]

I'd like to rotate the screen under program control.
Similar to the the Windows Control-Alt and Arrow Key.

Is there an API call to do this?

This would be for a program placed in the Startup Folder that rotates the screen and then does other things.   
It is for viewing music wit a monitor mounted sideways to read more like a sheet of paper - portrait orientation.

Yes you can use the functions ChangeDisplaySettings().
Here you'll find more info and a sample.
