The last time I changed the aspect ratio was when I was watching a movie on an old t.v of mine. Whenever I would watch a movie, It would give me the option to watch it wide-screen or regularly. Currently, I have a plasma-flatscreen that enhances the shot to fit more horizontally no matter what. On another note that doesn’t really have to do with aspect ratio but still relates to how images are depicted on screen, my T.V. uses high definition imagery. This makes all the movies and t.v. shows really sharp, making it appear like a soap opera, which is quite annoying!
