It all depends on the Laptop you have. You would for example need a Laptop with a VGA out port on it which you could then plug into the VGA port on your HDTV if it has one. Sometimes they call it the PC Input. Looks like your HDTV does have a PC Port, so does your Laptop have a VGA out port on it? Same thing with HDMI. Does your Laptop have a HDMI out port on it? If so, plug that into the HDMI In port on the HDTV. If your Laptop has neither, then you need some type of Card to Plug into it to give you that capability. Once your connected, you just need to set the HDTV to use the correct Input connection. This isn't Rocket Science. If you can do a Powerpoint presentation, I would think this would be a simpler thing to do.
