Why does a black rectangle box sometimes appear on a television screen?
Gotcha1958
Its to keep from blur.if it was any larger it would be enlongated and streached with slight blur.So to keep it correct and blur less,the rectangle is a visual affect to make it the right size so that blur does not appear.ALSO in movies this is used too.In homes when watching tv movies,its use to fit the format of a certain screen Example:a 42 in` plasma screen tv(as an example) would have a rectangle box of(ABOUT)38 in`.so diffrent format diffrent size.
