Q: How can I connect my laptop to my TV, so that I can watch

A: This greatly depends on what model laptop and TV you own. If your laptop has an S-video Out connection, then it’s a simple matter of purchasing an S-video to S-video cable and plugging it into the S-video In connection on your TV (if there is one). Of course, you can’t forget audio, so you’ll want to connect that as well. For that you’ll need a Stereo to 2x RCA cable, which you connect to the headphone jack on your laptop, and to the L and R Audio In on your TV.
