Sync timing adjustments on the XPression system are made through the XPression software to the Matrox card.
Navigate to:
Edit > Hardware Setup > 'Configure' Matrox XMIO2 > 'Board' Tab > Genlock > Timing Offset > Vertical
You can make changes to the horizontal timing of individual outputs on the Matrox card under:
Edit > Hardware Setup > 'Configure' Matrox XMIO2 > 'Output #' Tab > Horizontal Timing Offset > Fill & Key Offset
Try both negative and positive values in these offset fields, changes made to the timing offset will alter the timing of the Matrox card immediately
Let us know how it goes, or if you have any questions!
