Its not working.

MY QUESTION IS SHOULD I USE DVI-I TO VGA CONVERTER OR IS THERE ANY OTHER WAYS TO CONNECT TO TV PLEASE LET ME KNOW.

THANK YOU FOR ALL YOUR REPLY'S IN ADVANCE.....

DVI (Digital Visual Interface) gives you a higher quality picture. But for this you should make sure that your TV is an HDTV. You can purchase the cord for the same. It will cost a little more then the usual VGA cable. You also have DP output, so you can also use the usual RCA/composite cable to connect your laptop with your TV. If you have a support for S-cable, you can also use it. But you should remember that you will get the best quality pictures in the following increasing order.
S-video < VGA < DVI < HDMI
