Power cord to transfer info from laptop to hd tv and watch on tv

You don't want a "power" cord, you want a video cord.
Which one depends on the video out your laptop has, and the video in options your TV has. Look at the manuals for the two, you will find a match.

Get that type of cable, and plug in the TV to the out of the laptop, turn on the laptop, it will detect the TV as secondary display.
