Last night my laptop (samsung nc20 running XP) fell off the table and the screen cracked leaving me unable to see anything.

I have arranged for a it to be repaired but want to make a back up of several folders before it gets sent away. I was planning to use my parents LG LCD tv as an external monitor so I can see what I am doing when copying things to but after plugging it in nothing seems to happen (works instantly on another laptop running vista) and hotkeys seem to be of no use at all.

Does anyone know the series of shortcut keys I will need to do to get XP to use an external monitor?

Thanks in advance
