In hopes that this could help someone else. I have been running eyefinity on my 5770 on 3 asus 1920x1080 monitors using the dell bizlink active adapter for the last 4 months. In order for it to be stable every time I boot into windows I have to yank the dp adapter, and uplug the usb power, plug the usb power back in, and then plug in the DP adapter again. As long as I don't change resolutions my DP attached monitor will stay "lit".

Fast forward to today; I purchased 3 x HANNS G 28" monitors, mainly because I really don't like the 1920x1080, and much prefer the 1920x1200.

I hooked up the 3 monitors in place of the old asus, and suddenly my DP monitor looks terrible. I go into the OSD of the monitor and find that it is actually outputting 960x1200?
I found several other instances of people having this issue with the HANNS G monitor, here is what I did to fix mine;

Completely uninstalled ATI control center, drivers, the whole package.
I noticed on reboot I was still using the ATI drivers, and my DP monitor was functioning correctly at 1920x1200. Unfortunately I couldn't create a display group. I then proceeded to reinstall the ATI catalyst suite, but ONLY installed Control Center, not any other option (I believe it required the .net framework, and couldn't uncheck it)
I was then able to create a display group successfully at 5760x1200, and the DP monitor working correctly.

I still have to unplug my DP monitor and back in every time I boot windows, but at least it's working.
