some prick mod on the AMD forums keeps locking threads about the bezel management.

I posted another thread about it, which I fully expect to get locked too.

Your not going to get anywhere. I'm afriad, unless you brought an Eyefinity setup from scratch (monitors and all) your stuck with a "poor man's" implementation. It seems the path many took from upgrading current setups is fraught with danger, from the whole DisplayPort adapter confusion to now with bezel management not being supported on "mixed" setups.
I'm now stuck on this boat and the only way I'm going to get anywhere near a pefect setup is if I bite the bullet and replace all my monitors with the same 24" LCD. In my case, I have an "old" Dell 2405 which is brillant monitor, the best I've owned for picture quality by far and it is still going strong. But unforunately, being so old, getting hold of another two 2405's isn't as easy as walking into a store and purchasing brand new. My only option is second hand, and even then do you really know what your getting? And to top it off they can be hard to get hold of due to still being very popular in the second hand market.
That's why I ended up going the cheaper option and getting a pair of 20" Dells on either side. Works an absolute treat. But then along comes little things like this which detract from the whole experience. Oh well, guess it's time to start saving....... :(
