Hdmi and running program-do I need any drivers to run it?

[emakas]

I have a MacBook Pro and a Panasonic HD Plasma TV (TH-50PZ700U) and have connected an HTMI to each of their ports but to no avail.
Do I need a running program?
Do I need any drivers to run it?
Thanks, Jae

When you connected your MBP - did you make sure the "input" on your TV is selected to HDMI?
