Got this new Samsung TV and when I hooked all the connections up I turned it on and it plays with cable and it plays fine it is just really fuzzy ?

Make sure you have selected the correct resolution for the inputs.

How did you hook it up? Are you using basic cable or are you using a cable box? And if you're using a cable box, what type of cable box and what type of connection did you use?

Also, if you have an HD cable box, and it is connected through an HD connection, make sure you're on the HD channels (most companies actually have separate channels for the standard definition and high definition).
