I have a 38 inch LCD Vizio TV that is about 10 years old now which still works like new with which I watch only over the air broadcast TV and DVD movies. I'm thinking I should upgrade because I'm probably missing out on the latest features like LED displays and 4K. I don't need super fancy features but just something for an optimum TV and DVD movie viewing experience. I should get a larger screen size since DVD movies are shown in a movie size aspect ratio, but I have seen a TV in a home that seemed to have too large a screen for the viewing distance where you had to turn you head to watch the action. I am seeking guidance from all you smart folks.
