Good advice, except that you want to set your TV as the SECONDARY display using the nvidia tab that should have installed itself in your advanced settings when you installed the card. You will probably need to tell the software to detect your displays. PM me if you have any questions.

i think there also should be a clone feature that allows you to have both displays at the same time.

it should be under the side folder that pops out in the "nview" feature that should come w/ nvidia.(mine does)
