Nvidia Surround Portrait - Broken Menus

[xBlizzDevious]

It's not such a simple issue, this one...

Basically, some games have (what I think is) quite a useful feature where the menus will constrain themselves to a single display when using a Surround or Eyefinity setup.

However, they all assume that people are using a landscape Surround setup and I'm not - I use portrait. Personally, I prefer one big screen at a normal aspect ratio over the whole super widescreen thing and so I've stuck with portrait.

Games that have this "useful Surround feature" don't seem to have an option to disable it and so I always get my menus as super-tiny text and buttons on my middle 1080x1920 monitor.

Is there a way to fix this?

The game I'm wanting to fix it on most right now is Far Cry Primal, but the Battlefield series does it too.
