Different types of stereo sync connectors
VGA pin 12
Some graphics cards use pin 12 of the VGA connector (which originally is used for transfer-
ring DDC data during monitor identification) as stereo sync.
At the time of writing this, most ELSA cards using the revelator drivers use this type of
stereo sync. The AP-converter may use this if selected using “SST” command.
Left/right sequence in frame sequential stereo
The left and right frame coming from a frame-sequential source needs to be output correctly
to get an optimal viewing condition.
When you have moving objects on the screen, it is especially important that the left and
right frames are output correctly.
Usually the frames come out in pairs, where the left and the next right frame were rendered
at the same point of time. These need to be output at the same time. To make sure this is
happening, you need to know how the computer does this. You may change this sequence
by using the SSEP and SSP commands on the serial interface.
