I just excitedly downloaded the new 14.6 Beta drivers after I saw the new eyefinity mixed mode stuff, but I'm not seeing any way to change between fit/fill/expand. I'm stuck with the same old common resolutions that I had before. Hopefully it's not that my particular configuration is too "wacky" for it, or my card too old. Not the end of the world if this doesn't work, but I'd been quietly hoping for this feature for years now, so I'd love to get it working. Any ideas anyone?
