Acathla got in there as i was replying and outlined the basics,
this might also be useful....
on all laptops that have VGA connectors, there should be a key combination you can use to make the LCD also mirror to the VGA port, however as you say its hard to work with as it stands at the moment if you cant find that key combination.
assuming windows is running,the trick is if you can get a second app to the VGA monitor is to force the primary diplay to that instead.
simple way is to guess the windows bar at the bottom left click and grag it to the VGA sreen , then you have set the primary to the VGA....
another way is to start tightVNC server and have that autostart, then use another PC to log into it and you can setup your options and mess around al you like until it works as you want on the VGA port.
the best option is still trying to find the right key combinations to just mirror the LCD though.
its usually holding down the FN key and in my case F5 but you can try all the F keys with that FN key down and you may get lucky, look up the exact option for your model on the net OC is always a good idea, the user PDF manual usually has these options in it...
