I have a Dell T3600 workstation running Windows7, with 2 FirePro W5000 cards installed.
AMD Driver date is 8/16/2014
Each card has 3 outputs: 2 DisplayPort, 1 DVI-I
These cards are driving 4 NEC 46" X463UN monitors. (This will soon be expanding to 6 monitors.)
I currently am using 1 DisplayPort and 1 DVI output from each card, to drive my 4 monitors.
My problem is that one of the DVI outputs will just not work.
The monitor connected to that output will not see a signal and will go into PowerSave mode.
If I reboot the PC, or power cycle the monitors, then the non-working DVI output is normal, while the second DVI output stops working.
So only 1 DVI output will work at a time.
Any suggestions on what is going on here?
