Custom Resolution Utility (CRU)

[520st]

Hi, I am newto the forum and I have a special request.

I have 3 LCD monitors 1680x1050 running Eyefinity. This makes:
- resolution = 5040x1050 (to make thinks easier I do not take into account the bezels widths)
- ratio = 48:10

Is it possible using CRU to make:
- resolution = 3360x1050
.......... 1680x1050 on the middle screen
.......... 840x1050 on the right and left screens
- ratio = 32:10

Please see the attached picture to understand what I'd like to do.

This is a good balance between resolution/ratio/FOV for games. I prefer having this rather than a 21:9 monitor.

My 3 monitors are 22" Iiyama Prolite B2206WS.
I have 2 ATI HD7950 crossfire, Win7-64.

Please tell me whether this is possible or not

Thanks a lot for your help !!
