Hi Richard,

The MAC is a 2.66Ghz MAC Pro Running 10.4.8.


The peferences are set up correctly as per your screen shot.

In the catalyst control it reports 4 video channels.

In the HUd, inputs section there are 4 boxes and they show that all video inputs are off. If I tick the box it appears to try to load some settings and then returns back to off. I have tried versions 111 and 097.

Thanks

Ian
