It has an HDMI video port - ideally, you should connect it to an HDTV with HDMI input ports, but since you said it only has s-video and composite, you are left with very poor choices. You would need an HDMI to s-vdeo or HDMI to composite video converter, and none of these are cheap (a few hundred dollars)

You could get a laptop with a VGA external port and use the device in my first comment, as an alternative.
