if there is more info u can provide about the specs or model of the laptop id be a big help.
most laptops today should have a hd video, dvi, or a vga out. if it does then all you need to do is plug your monitor in and program it however you need to through your video settings.
if your laptop doesnt have video out...then you're out of luck.
try finding a local electronics shop that will let you use thier computer if there are no other options =)
