Summary: The TV picture quality was everything I was expecting, did use the picture set-up setting mentioned here and have no issues wit the picture quality. 3D is really nice option. Reason for downgrade is my SMART WiFi connection is not working, called Samsung and they said my WiFi router was too far away and I need to install a cable. Haven't done that yet as my DVD wifi works fine and has the same SMART options. Not sure why my $79 3D DVD WiFi works yet this TV doesn't.
Summary: Apparently this model has no input for composite video. This rules it out for anyone who requires closed captions, which are often garbled in digital transmission but render perfectly in analog.
Summary: I am an Amazon fan but this time I got this tv cheaper in a department store. My intention was to install this TV with a low profile wall mount. My surprise was to find that all connector in the back (except for 2 USB ports and 1 hdmi) where located facing out from the back of the TV. In addition to that the power cord is not recessed either. It comes out more than 1 inch from the back of the tv so when trying to use a low profile mount you simply can't.
