As people are upgrading their TVs they're looking to bolster their screen size too and the 50 to 55-inch mark represents the absolute sweet spot between brand new technologies, large screen sizes and great prices.Right now, this is where it's at. For a great many of us the 65-inch TVs are far too big for our living rooms, but even just that little step down to 55-inch screens can make a big difference without compromising at all on quality.
