I have a similar problem.. I have 2 Dell P2310H's and my 3rd monitor is a Viewsonic, now during my last install of Win 7 I lost portrait mode at some point which came back permanently after I disconnected and reconnected the Viewsonic once. I'm pretty sure it had something to do with it rereading the monitor's EDID. Since I reinstalled Win 7 however (new mobo) I don't have portrait mode available for the Dell's if I have the Viewsonic plugged in at all. It's bizarre but if I disconnect the Viewsonic I get portrait back.. dunno what to do about it.

I don't play Eyefinity in portrait but I like to use one of the Dell's in portrait occasionally and having to disconnect a monitor to do it is a pain..

In a huge stroke of WTF.

I swapped the 2 DVI monitor cables. Like, with each other.

Got portrait mode back.

Now I just need bezel compensation...
