I have a Barco 701s usually connected to a Quadscan pro via a VGA to 5 x BNC lead (using 4 x BNC). I have today got an iScan pro on loan and have conneceted it up with a component input from my Denon AVC-A1SR and using the same VGA to BNC lead to the pj. Unfortunately I cannot get any picture at all on the pj on any source with the iScan set to either RGB or YPbPr. Anyone got any ideas? I'm trying to see how much better (or not) the iScan is over my Quadscan. Any help appreciated. Thanks.
