How do I make skyrim a different aspect ratio than 4:3 in triple monitor setup?

[vogen]

I am using Haydens solution 0.9 at the moment, and I am using eyefinity on my crossfire radeon 6950s... Well it seems that it is defaulting the aspect ratio in game to 4:3 because everything is WAYY stretched out. I know each of my monitors supports 16:10, but I can not seem to get it to do 48:10. How do I make this happen? I watched videos of others playing at 48:10 when it isn't stretched... so I would like to play like that as well.. I believe my desktop is set up properly.. I am kind of new to eyefinity... So any help would be GREATLY appreciated.

Thank you so much for the help guys.
