If you want to extend your MacBook display to a TV in order to use it as a monitor, you must use the MacBook’s DVI jack. MacBooks, if they have an external display jack, will feature a Micro DVI or DVI jack, depending on model. This can then be connected to your TV. If you do not have a DVI port on your TV, you will need a DVI to S-Video converter cable.
