you'll need either an RCA cable, DVI cable, AVI cable, HDMI cable, or S-video cable, depending on what outputs your laptop has and what inputs your TV has. /end smartass. sorry. most likely your laptop will have an S-video and DVI/Analog cable output. if it's a newer laptop, it'll probably have an HDMI output, which will save you the sarcastic responses to "which audio cable to I need" :-P
