Vizio makes high-definition LCD television sets. One source you can use to get a high-definition signal to the Vizio set is through Dish TV, also known as Dish Network. Setting up a Dish TV satellite system requires you to use an HD connection from the Dish Network receiver to the Vizio set. Dish Network has a component output and a DVI connection, and are both used to transfer an HD signal to a Vizio HD set.
