I'm curious if the latest 14.9 drivers changed anything with this. Lists "Eyefinity Display Alignment" as an enhancement: Enables control over alignment between adjacent monitors.
I'm not 100% sure what this means, but I guess it doesn't mention rotation.
I saw another review of 14.9 Eyefinity stuff, and it mentioned PLP still didn't work.
It's easy to find lots of different forums with questions about this. Too bad AMD isn't listening.
I've replaced my AMD card, but would put back in or get a new one if I could do different rotations in SLS mode.
