Reply To: No Sync Intellivision


Hi…I had the intellivision -> scart cable -> scaler -> hdmi monitor setup working. The scart cable is some generic one I bought off ebay to demonstrate my mod is compatible with Genesis 2 rgb cables. Pulling one of the V1-V4 wires verifies the scaler is processing rgb and not composite video. The picture quality is better than in the photos below but is still not super sharp. The scart cable is neither 75 ohms or ground shielded so that is the first thing I want to try changing. It’s also a cheap scaler so it could just be that. Either way I’m happy that my mod works with standard unmodified equipment.
