Got an issue here and I'm stumped. Had a successful 3X1 eyefinity setup with one R9 290. Recently added an R9 290X with it in crossfire. Now I can't get eyefinity to work. The 290X is the main card now so everything is plugged into it. I've got 2X dvi and 1X hdmi. I can get all three monitors into an extended mode in both Windows and Displayfusion. When I go to create an eyefinity group I can choose the orientation (3X1) and it just says "to continue, start a new task" but I have no idea what this means. Any help would be greatly appreciated!
This issue is now fixed - it was because I was using Beta drivers instead of Omega. Hopefully this helps someone else.
