When the TV picture format is set to AUTO ZOOM, the picture will be displayed according to the broadcast format, i.e. TV will display a 4:3 broadcast in the 4:3 format & a 14:9 broadcast in the 14:9 format.
If you wish to set a specific format, proceed as follows:
NOTE:
This TV does not have a 4:3 option in the list of available formats. If you want to view TV channels or material from other sources according to the broadcast format, you need to set the picture format to AUTO ZOOM
If the picture from external sources does not display in the correct format, you have to set the format on the external device
