My television set has a screen that is 45 inches high by 60 inches wide and sits on a cabinet that is 45 inches high and 114 inches wide; I have no more space available in the apartment. I like movies and my old TV has an aspect ratio* of 4:3, which makes it impossible to fully see the scenes; a 16:9 aspect ratio SmartTV would be ideal for watching my movies. Here I am, in the store, thinking about buying it; however, only the height is listed in the specifications, which is exactly 45 inches. *In case you don't remember, the aspect ratio is the ratio between the height and width of an image. What is the width of the new SmartTV?
