Firepro W9100 + 30" 4k NEC monitor stops working/crackles waking from sleep

Hello All!

 

I have a workstation built for graphics using 2 Firepro W9100 cards from Sapphire. 2 - 30" 4k NEC SpectraView and 2 - 24" NEC MultiSync monitors are connected via a display port to MiniDV ports on the card.

 

A hellish problem Ive been having, pretty much since the beginning of the build being on, is upon waking from display sleep, not full computer sleep, the 30" monitors will stop functioning and make a crackling sound from the NEC built-in speakers. The 24" NEC monitors don't have this issue however, they wake up just fine without error. To note, I have sound disabled on all the monitors.

 

To fix this issue I have to unplug the MiniDV end from the card and move to another unused port, sometimes trying 2 or 3 ports before finding one that does not continue the problem.

 

This has forced me to stop using my 30" monitors fully because if I step away for a short time the screens will be crackling loudly, disturbing my workmates. This is of course insane given the cost of this equipment and the need to use them without error.

 

This issue is driving me and those near me crazy! Has anyone experienced such an issue or do any AMD engineers have any ideas as to what may be the cause of this?? Im hoping to find a solution because this equipment is not cheap and I expect drivers to be solid with such an expensive GPU. I have reinstalled the driver 3 times, twice to try to fix this issue and with one patch for the infamous Photoshop CC GPU acceleration problem.
