That's a likely possibility. If your laptop has either HDMI out it should be easy enough. If it has a VGA out, it may also be easy given your TV has a VGA in. If not, you'll likely need to pick up a cable with the ends you need or an adapter or two. It's not going to hurt anything for you to try to establish a Wi-Fi connection to your set but don't be surprised if it fails to work.
Good luck.
