Hi mate. This has been driving me insane too. Unlike you though I still cant get mine to work.
I am using View 5.2 and Grid K1 card
The only way I can make the K1 card activate is if I unistall the svga card from device manager and for rest of that session the k1 card is used. If I restart, it detects the svga card and defaults to it and I have the problem again.
I have gone into the Workstation>View system topology>EDID Monitor. But it does not allow me to export. Only import. This does not exactly correspond to what you were saying. Any ideas?
