Hi,
Nickbuol is quite correct in this. I'd be reluctant to try dual centers to either side of a video display. If you were centered in the sweet spot exactly mid-way between the two centers, then that would be fine. It would phantom image the dialog exactly at the screen center. But for anyone sitting slightly to one side or the other, the dialog would default to one of the dual centers closest to the viewer, which would move the dialog to the left or right of the screen--not desirable.
Dual centers only work well, above and below the display, not to either side.
Regards,
Alan
