I have my monitors set up side by side in landscape mode. I've had an eyefinity setup for almost a year, but I wanted to try out doing portrait mode instead of landscape and I don't see any option to change that in the "Screen resolution" in windows. In CCC the orientation mode is grayed out.
Was anyone able to figure this one out? I have the same problem. I have three DP monitors and one DVI monitor and the only monitor that gives me the option to rotate is the DVI. No option to rotate for any of the DP monitors?
greyed out means your graphic card is capable of doing it, but some thing is preventing it from making it possible/happen. For example if you already select 1280x1080, this is by default landscape, so setting would grey out. Just an example, not saying that's the problem in your case. Portrait/landscape mode is set by the graphic card, not monitor or O/S. Seek the gx card manufacturer or help.
