I've already got two of these Diamond BVU195's running at 1920x1200. My calculations indicate I have exceeded the USB 2.0 bandwith by 7 times . I am looking to utilize this firewire port that is doing nothing to reduce the load. I've already got the mini displayport utilized. I'm running 3 monitors possibly 4 in the future not including the laptop LCD. Where can I find firewire adapter?
