Connecting laptop to TV?

If your laptop has an HDMI port, buy an HDMI cable. If it does not buy a VGA cable, both of these work with any device with the proper port. There is no such thing as a "connection wire" specifically for an HP laptop. As for the one you linked to, yes that will work, the package consists of one VGA cable for video, and a headphone jack to RCA cable for sound, though if your laptop has an hdmi port, which after some research I can safely ume it does, buy an HDMI cable, it will offer you the best picture and sound quality in one single cable. Once again any HDMI cable will work, just make sure you get one that is long enough to fit your needs.
