Does anyone know which "standard" is used for the composite video
signal on the IBM color graphics adapter? I've looked thru the 1.0 
and the 2.0 Tech manual, and haven't found a thing.

We have a standard direct drive color monitor attached to our system.
For demonstration purposes we tried to connect a second monitor using
the composite video jack.  We did get the correct picture on the
second monitor, but the color information was all wrong. For example
an white picture, was white, blue, and orange on second monitor.
Initially we thought that the composite video circuit on the board
was defective as we interchanged differing monitors for the second
monitor with identical results. We also tried another PC system with
a second color graphics adapter with similar results.       

Any help or suggestions would be appreciated.
