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.
