Laptop screen for pc

Hello,
its in the wrong section but no one has replied for like an hour so ive come here lol.

im using my pc and its in need of an update,
and I need to take it to my parents house for the net.
the problem is they dont have a monitor or tv I can use.
So the question is can I use the laptop my parents have?
I use hd for my pc and there laptop has a hd port,
so is there a way I can use the laptop screen for my monitor?

thanks alot
