In addition, you can choose between two formats: 4 / 3 and 16 / 9. If you love watching movies or DVD format movies 16 / 9 required naturally. By cons, if you look especially television and its programs, series and games, the 4 / 3 format will be most suitable. Finally, note that for a screen diagonal of 55 inches, a distance of 2.20 m will be needed between the screen and the place where you look (diagonal multiplied by 4).
