It really depends on the type of equipment you have. Does your laptop have a HTML port? And does your TV have a HTML port? You can google your Dell laptop on how to make the config settings for displaying on an external monitor (TV) for your particular laptop model. I have done it with the VGA port to an external monitor very easily. The HTML will need some special settings depended on how old your laptop is. Good luck.
