3x1 portrait setup

[Xenolith]

I currently have 1x3 landscape set up. The control center won't let me rotate to landscape... rotation is grayed out. It still won't let me rotate if go to basic mode, and only have one monitor enabled. The only time I get rotation as an option, is when I extend to another monitor. I've had a 3x1 extended setup in portrait mode, but once I try to do an eyefinity grouping, it reverts back to landscape. Any pro-tips? This is on a 290x

This is why I use Catalyst 13.12. I had the same issue in 14.4. With 14.6 portrait works but bezel compensation doesn't.
