“The Matrox MXO hardware is neat, but it would require an ADDITIONAL graphics card, an ADDITIONAL monitor and I don’t know that we have room for that additional PCI card in the G5 Dual 2.0GHz. Does anyone have any working knowledge of having tried this?”
no. between second port of the graphics card and your second monitor. then use the “Full Screen Playback”. Is cheaper than the MojoSDI…
