Eyefinity Displayport problems, no bezel comp

I just got done setting up my friends Eyefinity setup, but i've run into some big problems.

His computer specs.

Phenom II X4 955
Asus M4A785TD-V EVO
4GB DDR3
Sapphire 5850
(being honest for diagnostics sake) non-official Windows 7
Catalyst 10.5
3x ASUS VH242V (HDMI-VGA-DVI)


Mine

Phenom II X4 965
MSI 790FX-GD70
4GB DDR3
XFX 5870s Crossfire
Official Windows 7 Home
Catalyst 10.4
3x ASUS VH242H (HDMI-VGA-DVI)

1. Ok, number one problem being i keep running into display port link failure. Whenever I try to run most games, it shuts off the middle (DP>VGA) display. The only way I've been able to recover it is to unplug and replug it from the graphics card. Eyefinity still is running, the middle display just doesn't show anything.

Perhaps it's the dongle (he bought a ATI certified Accell dongle)? I tried my own dongle (Accell) which i've been using with eyefinity for months now and still no luck. Maybe the VGA cable? Still nothing with different cables.

At this point i'm thinking that maybe the non-official version of Windows 7 is conflicting with the ATI drivers. Maybe, I don't really know. We both use the same monitors and the same hdmi-vga-dvi setup.

2. The second problem i'm having is that Catalyst won't give me the option to compensate for bezels. I got eyefinity up and running with no problems, but his...not so much. What also doesn't make sense is that our computers are damn near the same.
