On Windows? ChangeDisplaySettings. No idea about other OS. Are you
sure though that another approach might be more useful?

There are exceptions to everything, but normally the end user does not
like a program to change the screen resolution he has chosen.

If his app is running in fullscreen, then it is legitimate to switch
screen resolution, of course app need to store original setup and on
exit or crash set it back.

Attached is a basic example, the sample itself does not run in
fullscreen, it does:
- store original setting at startup
- list all possible modes
- on a click in listbox the mode will switch
- at a normal program exit the original mode will be restored

*Windows only*
