Trying to help someone fix their Digital Performer setup. They have a Mac Pro with two video cards, one Nvidia and the other Radeon. They're running four monitors off this setup. Two of them are connected to one card and the largest (looks like a 52" Sony HDTV) is devoted to one card. The third monitor is hooked to another Mac Pro (has all the synths and music libraries) that can be accessed by the other computer via the network.
Here's the problem. The output to the 52" monitor isn't working.
Additionally, they want to be able to toggle between the three screens so they can get them up on the 52" monitor individually and go back and forth between them.
What do you think?
I'm guessing it's the two different video cards and the drivers are conflicting.
