INPUT CIRCUIT CONFIGURATION
Display device uses an internal
source such as a built-in tuner to
provide a video signal.
Display device uses a video signal
from the SCART connector and sets
the display to 16:9 aspect ratio.
Display device uses a signal from the
SCART connector and sets the
display to 4:3 aspect ratio.
