So I have 3 monitors:
Center-> 1920x1200
Left -> 1920x1200
right -> 2048x1156

I want a 5760x1200 eyefinity resolution. Additionally, the right monitor has a much greater ppi than the other two, so the only way to make a straight line match across all three is to resolve the right monitor at 1920x1080. What I want to do is "trick" eyefinity into recognizing the right monitor as 1920x1200, and render the image as an overscan. This way, I can use the entirety of my other two monitors and keep an even ppi. What I have in mind happening, then, will be an overscan resolution, so that the monitor will actually only render 1920x1200 on the right monitor and the extra 120 pixels will be cut off. Hopefully, nothing of gaming importance will be lost in that 1920x120 section.

Is such an overscan possible? How? Do I trick the Catalyst Center or simply eyefinity? I just hate to get stuck with a 1920x1080 1:1 on my 1920x1200's.

I have two other inquiries as well:
How is eyefinity set up?
Where can I buy a display-port to DVI active adapter? Amazon has one at $35 but it is only available for pre-order.

I just came up with the exact same question as you today, as I was trying out Eyefinity on 3 different sized screens for the first time.
I kind of doubt it would be easy, but it might be possible. Let's hope someone else has an idea.

To answer your second question - Eyefinity is really easy to set up. At least it was for me. Just plug in 3 monitors, turn on your comp, go into CCC, and "group" the three monitors. It's pretty intuitive.

Regarding the adapter - I've heard that you need the very expensive active dual link dvi to displayport to actually get it to work properly with DVI (I doubt the $35 one is really "active")
So I used a $30 Displayport to VGA, and just used the VGA port on one of my monitors. Seemed to work fine. The only drawback with VGA is that you're limited to 1920x1200, but this is no prob for me.
The monitor that I plugged that into seemed to be slightly off color-wise, but I'm pretty sure it's just the monitor's settings.
I have one 19" @ 1440x900, one 22" @ 1680x1050, and one 28" @ 1920x1200. They all defaulted to the lowest common denominator, 1440x900. The difference between the 28" and 19" is jarring, and not really worth keeping. But if your overscan idea worked, I could just cut the size of the bigger ones down.
