This is a post I made on the AMD forums and I am reposting it here to try and get the most input on this particular problem.
This is a game specific problem that leads me to believe it is a deeper issue. This is a rather long post and prehaps it should go in the Eyefinity forum section but it was a specific game that brought it up.
I am trying to figure out why I get no HUD centering or Eyefinity detection from Deus Ex Human Revolution and I'm starting to think that the problem may be deeper than just the game. The lastest patch for Deus Ex Human Revolution stated that is fixed the lack of HUD centering for Eyefinity users, but I still have no HUD centering or Eyefinity detection for the game despite having used Eyefinity for over a year now and thinking that my Eyefinity setup is fine.
However in trying to figure out why I am still experiencing this problem a helpful poster in my Steam thread about the problem gave me some insight into what may be soem problems with my Eyefinity setup.

The Steam thread eventually lead me to this thread and specifically the last page concerning improper Eyefinity detection.

Now I am wondering if I am doing something wrong in setting up the Eyefinity display and grouping and such. In the thread the discussion is about duplicating the desktop across all three monitors and the actual Eyefinity being incorrectly recognized.
Upon a fresh install of the current 11.8 drivers my setup in CCC and Windows look like the following:
After this I would always create my Eyefinity 3x1 group and then apply bezel adjustment to get a resolution of 6048x1080 and I always assumed it was working fine.
This is what things look like after creating the Eyefinity group:
But based on the Codemasters thread and the fact that I get no HUD centering or Eyefinity detection in Deus Ex Human Revolution I think I am doing something wrong and thus I get the extended resolution detection and it says 'Eyefinity Group' in the CCC but something is not detecting right. The Codemasters thread talked about duplicating the destktop across all monitors but I do not see that option available anywhere when setting up the monitor grouping. Also the third monitor does not appear to show up in the Windows display settings before or after creating the Eyefinity group.
Anyone out there who has a clue about this and can give me any more insight or help? I have a feeling I am doing something wrong but after assuming I was doing it correctly for so long I am not sure what I need to do differently. I use a Powercolor 5970 card and three Acer H243H monitors for my Eyefinity setup and am currently running the 11.8 drivers w/CAP4.
