NICAM transmitted signals provide stereo sound whilst viewing the TV in STEREO mode, thus giving the user even greater listening pleasure. The TV also provides 16:9 (Wide Screen Format) viewing capabilities, together with automatic wide screen detection software built in.

16:9 Features
Various broadcasting stations now transmit movies and programmes in true wide screen format, especially some satellite broadcasts. Built into your TV is software that detects these signals and automatically switches your TV to the correct format. However, some broadcasters do not transmit the automatic sensing signal, and thus the TV will not recognize the format being transmitted. The above problem may be overcome simply by pressing the 16:9 button on your handset.

example 1

First identify the type of signal being transmitted. If it is a 16 x 9 wide screen broadcast viewed on a 4 x 3 normal format, then objects or characters appear tall and narrow (see example 1). By pressing the 16:9 button on your handset the screen is compressed to a 16 x 9 ratio. This is the correct ratio to view true wide screen broadcasts (see example 2). If the 16:9 button is pressed once more the AUTO function is set. The TV will automatically detect the broadcast and switch to 4:3 or 16:9 ratio. We recommend AUTO is set for the majority of TV viewing.
