Hi Derek,
To show anything on your TV that is on your laptop screen, it is just the same as for tablets. Depends how much advantage you get from doing so, screen size wise. Here's a link to the Amazon page on HDMI cables (make sure that you check both for connection type - there are different sizes, and also for cable length - will the cable reach the TV from where the laptop is situated?).

Amazon HDMI Cables

I found a pre installed cable in mine which starts in the top rear left locker and terminates inside the underseat locker. no plugs on the ends
