Because you can't configure the settings unless you see the primary screen.
It is that simple.
Hi,
I was just wondering why an external monitor wont work with a laptop with a broken screen i have. I've tried two different montors (one vga an one lcd). I've tried pressing fn & f10 but just after the xp loading screen it goes back to the laptop screen again. i can hardly see anything on the broken screen. i was just wondering if there was anything else i could try?
thanx
Dan
