do I have to buy an hdmi cable for my new LG flat screen tv

[lita.woods7]

Is an HDMI cable necessary?

Depends on what your trying to hook up to it.

If your are just using the built in tuner and apps then an HDMI cable is completely useless. If you are going to connect an external source to the TV you will most likely use an HDMI cable to do so.
Did some salesperson try to sell you one?
