Please be aware that a scan converter may be outputting a format and frame rate that the Ki Pro does not understand natively. Additionally, you mention RGB; the full size Ki Pro product only supports component analog Y/Pb/Pr input, not RGB.

We just tried going out of a folsom presentation pro, component out, 1024 x 768 59.97hz directly into the component input on the kipro and can not get a signal. We take that same cable right into a monitor and it's good to go, so the cable is good and the output is there.
We've tried all of the different syncs on the input selection of the kipro component input to no avail.
