Well this has nothing to do with Vlc ...
But if your on a laptop i suggest you just hook up ur tv to you laptop threw s-video cable, much better would be Dvi cable but since you gave us very lil info to go on.. it hard to help you out.
question for you
have you ever hook up A computer to a t.v?
what kind of tv do you have lcd( flat screen) older ctr?
what kind of connection do you have on that tv? s-video? dvi? hdmi ?
Once you hook it up to you t.v your laptop should recognize it right away as new display, then you can just move vlc on too that screen and enjoy your movie
