Avis bought a 75" 4K TV for Christmas and she isn't sure that her cable will give her 4K. Leo says that the only way to get 4K is through Netflix or Vudu. And because it's over the internet, it's highly compressed. There really isn't any other 4K content until 4K Blu-ray players come out later this Spring. Then she'll start seeing movies being released in Ultra HD Blu-ray. What's a good brand? Leo says Sony is a top brand to look at.
