COLGeek :
Are you sure you have CF enabled in CCC?
All right: thanks to all for their time and trouble. After quite a lot of searching and reading and trying different cable configurations, the definitive answer is:
If Crossfire is enabled, the cable configuration MUST include one monitor connected via the DisplayPort. Mine, right now is:
DVI-D to Monitor #1 (left) (Card #1)
DisplayPort to Active DP/DVI-D adapter to Monitor #2 (Card #1)
DVI-D to monitor #3 (Card #1)
Card #2 is not used for video output in Crossfire, so far as I can determine.
If Crossfire is NOT enabled, 2 DVI's from card #1 and 1 DVI from card #2 works fine. But only in 1920 X 1080 resolution for each monitor. In fact, at least with Win 8.1, I have a downloaded "Classic Sportscar" theme and the left and right monitors show 2 different cars/scenes while the center (working) monitor shows the desktop. Cool.
Tomorrow I'll play with Crysis 3 and 3-monitor play in Crossfire.
More to come. Thanks again
P.S. Why don't the different video card manufacturers provide at least SOME sort of guide for this. No manual of any sort was provided in the OEM Asus box.I found a video on AMD's website explaining this quite clearly. Asus support was bloody useless. And the various vids on YouTube were...sophomoric at best.
