Okay..
So far I haven't been able to resolve the "unable to initiate the display wrapper problem".
These cards also heat like crazy.
Right now I have the rig set up with three cards, each spaced out so the air circulates and keeps the cards cool.
This set up works, but it's a bit disappointing to not have 4 cards running.
Does anyone have experience getting 4 6950 cards running without the display wrapper problem and without heating problems?
I haven't played with the bioses etc. but I don't think it'll help this one. Ideas?
Mining hardware comparison shows someone running 4x6950, but most of others like this video give me the impression that in general 4x6950 cards are not done.

I already decided to return the 4th card, but if I hear from you now, I'll keep it and make it work.
