Connecting dual monitors and adding a monitor/LCD tv to laptop is two different things. I have done the later while playing games and watching movies so i can help you in that. If you want to add a LCD tv to your laptop then you need a HDMI cable. Just put one end to tv and another end to laptop, select HDMI option from the tv remote and you are done.
If you want to connect a monitor to your laptop then i guess you need to check your monitor cable. If it's DVI cable then you need a DVI-HDMI converter since laptop don't have a DVI port.
If its a CRT monitor then it should have VGA cable and still laptops support VGA port, so just insert the cable to the respective port and you are done.
