...notes on wide screen features
Various broadcast stations now transmit movies and programs in true wide screen format. Your
TV can detect these signals and automatically switch to the correct format (when in AUTO mode) .
However, some broadcasters do not transmit this automatic sensing signal, and so your TV will not
recognise which format is being transmitted. This situation can be overcome by simply
16:9 format
The picture (right) illustrates a true 16:9 wide screen picture
format. This type of picture fills the entire TV screen. The 16:9
mode can also be manually selected if desired by pressing the
button
Please Note: Your TV will automatically switch to 16:9 mode
when it receives a true 16:9 Wide Screen Signal through the
external RF aerial or external AV sockets. You can override this
change by pressing the 16:9 button on your handset to switch to
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).

The 14:9 format (right) is the medium between the 4:3
and 16:9 ratio signals. When this mode is selected thin
black bars appear to the sides of the screen.
auto format
The Auto format is also one which can be selected manually.
Auto mode automatically detects various screen formats that
are transmitted in either conventional (4:3) or wide screen (16:9
or 14:9) format. After detecting which signal is being transmitted
the TV will automatically switch to the correct screen ratio.
