I had the same problem. What you need is a higher quality, higher speed capable HD cable and nothing more, but you might also need to adjust your cable box settings or the TV's settings. Make sure that your TV is set to the same video setting as your cable box and that your cable box is sending the correct frequency/size to your TV from the box.
