There are some variables here, as you did not prvide much info, so I will go thru a few. If your MBP has a HDMI port and your tv has a HDMI input all you need is a HDMI cable. If your tv is HD it will have HDMI input If your MBP has a mini dvi port you will need a minidvi adapter to HDMI and a HDMI cable to the tv. If your tv is HD it will have HDMI input. If your tv has a VGA input you will need a mini DVI adapter to VGA, and a VGA cable. If you have an older MBP with the large DVI connector you will need a DVI adapter to what ever the input on the tv is.
Sorry about all the links, but with so little to go on I included a bunch of stuff, I would think you should be able find what you need.
All the best
I have a mid-2010 15" MacBook Pro and I hook up to my TV using an HDMI cable with an Apple adaptor, which plugs into the Mini Display Port on the MacBook.
There's probably a way of hooking up using WiFi, but my TV doesn't support it unless I run an Ethernet cable from the TV to my Belkin Router !
The HDMI cable serves it's purpose . . .
I hope this helps, good luck !
