Eyefinity problems with 5850 setup

[RazorHack]

Hello, I'm having trouble with my setup and was hoping some of you could tell me what is wrong.

I have a Asus 5850 stock graphics card.

3x BenQ 24" LCD screens, connected with 1xHDMI, 1x DVI-I and the last one to the Display port using the active Bizlink adapter from Dell.

When I try to choose 3x1 grouping setup in CCC, only 2 of the screens show a picture. The last one just turns blue. I've figured out that it must be the resolution is too high, because when I choose 4800x900, I can use all three screens, and it works fine. (tested in several games) But the 5760x 1080 option is greyed out when I right click the ATI icon in the system tray. I've read about people using the 5850 card for this resolution, so I'm wondering why it is greyed out for me.

Is it my dual core CPU that is the problem? (Soon to be upgraded, it's in the mail) or is it the card itself. I was told this active Dell adapter should work, but that may not be true? (Strange that I can use the lower resolution then)

I need your help guys.
Thanks in advance!

Hmm sounds like it should work,m you sure your adapter is running properly? Have you tried just using that one and the screen that is connected to it at 1080p? Only thing i could think of atm :/

What are the port options on the Asus card? Why can't you use 1xDP and 2xDVI?
