Q: Mid-2011 iMac won't boot Win 8.1 (BC) w/ ACD 30 attached

I have a 27" mid-2011 iMac Core i7 with two external displays, an ACD 30" and a 20" HP. I spent a great deal of time watching Win 8.1 in a reboot loop after install (Apple Drivers installed fine), sometimes with vertical lines down the ACD 30 (nothing on the HP). (I didnt expect Win to notice the more than one DisplayPort screen.) Finally I disconnected the displays and I booted into 8.1 fine.

 

IS this a thing? Others share this experience?

 

Thats not the end of my Boot Camp woes, but that's all tied to this issue.
