Issue: Attempting to get AMD Firepro w7100 to run 4 monitors. The picture below is the current set up. My understanding is that it can run 2 passive connections and 2 active connections fine, but I can't seem to replicate those results. I can only get three of my monitors to work. The passive DP to DVI is not working. Any ideas as to why this might not be working? Driver is updated to the latest.
