I got my ISS-6020 Moome HDMI card running last night, but wanted to compare the output of my digital cable box using HDMI/Moome versus component. My XG will handle both component and RGBHV signals just fine, so I hooked the cable box component output into one of the ISS RGB inputs. I can't seem to get a signal output from this input. Does the ISS pass component signals through the RGB inputs/outputs or does it need to see the sync signals too?
