I've tried every combination of sync settings on both the d4 and xrgb 3 but I've only used a ps1 with luma sync scart cables to test the image. I'm waiting until next week for my Saturn to be repaired so I can try with that.Fudoh wrote:no, that's definitely not it. As mentioned before I had the XRGB-3/XSELECT-D4 combo running for a few years and I didn't have any problems. I think there one source which didn't work when connected to the D4's JP21 input (Mega Drive maybe?), but in general I routed most of the systems through the D4 before passing them to the XRGB-3's back-RGB input.
I guess you tried all the D4's sync options from the extended menu (sync tip etc) ?
Are you sure when you used that setup you weren't using d terminal connections between the 2 units and not dsub15?
