Whats the difference in the LN5700, LN5750 and LN5790?

Is it just remote sytle that change?
Asked by: Vono
We appreciate your interest in these televisions. The primary difference between the 47LN5700 and the 47LN5750 is that the LN5750 series provides the Magic Motion Remote Control, while the 47LN5700 must have this controller purchased separately. The LN5790 requires the external WiFi Dongle Adapter in order to connect wirelessly to your home network. It also requires the Magic Motion Remote Control to be purchased separately. However, the LN5790 also comes packaged with a Sound Bar.
