4:3 format
The conventional picture format for most broadcasts is the
4:3 ratio signal which gives black bars to the sides of the
screen and this is consistent with screen compression (see
right).
C14:9L format
The 14:9 ratio is the format that is
sometimes transmitted by the
broadcasting stations. The C14:9L
format is used to expand a 14:9
broadcast so that it produces an
image of true proportions, but because
of the original ratio the screen will have
thin black bars to the right and to
the left of the picture.

C16:9L format
The 16:9 ratio is the format that is
usually transmitted by the broadcasting
stations.
The C16:9L format is used to expand a
16:9 ‘letter box’ broadcast so that it
uses the full screen to display the
picture so that the image does not
appear ‘crushed’.

panoramic format
The panoramic mode emulates that of a wide screen
broadcast for 4:3 transmissions. This is achieved by
maintaining the proportions of the centre of the screen while
shrinking the images on the top and bottom of the screen.
Note: This mode is generally recommended if AUTO is not
selected
C14:9LS format
Some broadcasters transmit in a 14:9
format, which appears with black
bands down each side of your picture.
C14:9LS enlarges the picture (which
can cut off the top) so these black
bars are no longer visible.
