Sony LDI-100 Series HMDs
D100 Stereo Connection
The following information on hooking up the stereo HMDs (LDI-D100B and
LDI-D100BE) is provided by Sony:
Connector:
On the LDI-100B, the "AV In" connector on the back of the adapter is used
for composite video and stereo audio using the AV cable, which is a the
conductor connector with Video-Yellow, Audio Right-Red and Audio Left-White
RCA pin connectors. The AV In connector is used for "Control In" for the
D100B. The White RCA connector is used to input sync signal to indicate
the polarity for left eye and right eye. The rest of Red and Yellow RCA
connectors are used to select 2D mode or 3D mode. This will be described
in the printed documentation.

Sync Signal:
For stereo, you do not necessarily have to input a separate sync signal
as the LDI-D100B can automatically lock to the sync signal of SVGA. When
the polarity is not correct, please use the switch that you will find on
the side of the adapter that says "Polarity A-B". This allows you to flip
the polarity for your eyes. Still, 3D mode has to be selected to view in
stereo, which can be easily be accomplished by plugging "Mono 3.5mm Mini
Phone audio plug" to "Control IN" or connect RED and Yellow connectors
of the AV cables to each other.
In case you want to feed your own sync signal,
here is the signal format:
