Help with setup of 3x1 Eeyefinity + 4th extended desktop

post #1 of 2
Thread Starter 
Hello all,

I'm trying to setup a 4th extended desktop display to work in conjunction with my 3x1 Eyefinity setup. Here's my problem: ATI CCC will only let me output to three displays and not four. Every time I try to output to the 4th display, no matter the configuration, I get an error message from CCC informing me I cannot do so. It doesn't matter if I try to have all desktops duplicate one another, if I have 3 duplicate and one extend, or if I create the 3x1 Eyefinity group + one extend; all listed configurations require me to disable one of the 4 displays.

Here is some additional information about my setup / system -

My four monitors are connected in the following manner. 2 out of 4 monitors are connected through the mini-DP ports. The first one is using an active minidisplayport to hdmi adapter. The second monitor is using an active minidisplayport to DVI adapter. Both active adapters are "approved" by the ATI website. My third and fourth monitors are connected through the two DVI ports on the back of the card. Please note - I am only connecting these monitors to one card. I am not trying to connect them to two video cards.

Here are other specs on my system:
Windows 7 Ultimate 64-bit
ASUS M4A78T-E mobo
Crossfire XFX 6950s 2 GB
8 GB DDR3 1333 Mhz RAM
2x500 GB HDD
750 Watt PSU
HT Omega Claro Halo Sound Card

Monitors' make and model
3x Dell U2410 1920x1200
1x ACER T230H 1900x1080

Thanks in advance for any advice offered. Peace.

I personally run eyefinity but never have tried to hook up a 4th when I was running crossfire.

Not 100% sure could have sworn you can only have 3 monitors running out of 1 card though.
