external monitor read

Specs: Windows Vista
I connected an external monitor to my HP laptop equipped with Vista and after some adjustments, everything was fine, till I messed up with the possiblities of display: I was asked to use either "monitor + laptop" , "laptop + monitor", "laptop" or "monitor", I choose "monitor" which was not the right solution. As a result my monitor shows a moving white box written "input not support". And that's it! Of course the laptop is all black when I connect the monitor and the monitor doesn't show anything else. I can't reverse this as I can't display a normal window. Please help!

There should be an Fn and F key combination that toggles between the internal and external screens. Alternatively, try restarting in safe mode - this should only work with the internal screen - and you can then undo any changes you made before rebooting as normal.

Thanks John. I finally found that, for my computer, the key to toggle between monitors was Fn + F4. Once I could see the screen again, I could work on the best view for the external monitor. But I could not remember which way I took to reach this wrong setting, which is not so important as I have now found this Fn + F4 shortcut.
Thanks anyway.
