Why does the registration web page not show my LCD model number?

I purchased an LCD model number LN46D7000LF. When I went to register the product, there was no selection for this model number. Instead, I chose a different model number to register. Thanks, Rick

What is the purpose of the network connection?

I have my tv hooked up to my network, wired. But what is its purpose? I don’t see any options for going online or to use any of the Apps. Does it have a real use purpose?
