Info-Mac

I have purchased this software and absolutely love it only problem I have is spanning I don't know what offset to use I am on a Mac Pro that is hooked up to 8 43 in Samsung Monitors running 720 P what offset would I use for Top Bottom Left and Right to fill the screen I played with it but can't quite get it to work any help would be greatly appreciated

That depends on how you have the monitors arranged. Ideally you would have a video that is rendered to the same aspect ratio for your monitor arrangement, thus not needing any offset.

So what would the ratio need to be I have two rows 4 on the top and 4 on the bottom?

Well that would be twice the width of a standard video, so 32:9. Basically make a video twice the width of a standard HD video.
