Walmart tends to sell specific, de-contented electronics (i.e. specific SKUs to get to lower price points). I got a samsung tv from walmart a year or two ago and its been great. Only 2 HDMI ports, but that was fine for me. The other retail models outside of walmart have quite a few more.

Fwiw I have had other brands and keep coming back to Samsung after they start to develop problems.
