distortions.

Just
Use Just when you wish to expand a 4:3 picture to fill the whole screen
(rather than watching a programme with black stripes down the left and
right sides of the picture).
The 4:3 picture will be stretched horizontally so that the image fills the
screen, this is done in such a way that the stretching is only obvious at
the left and right edges of the screen.
4 : 3
4:3 will display a 4:3 picture at its standard 4:3 size with no aspect
distortions.
