Hi, I recently set up a 3 monitor eyefinity on a 6950 crossfire setup with 3 27" ve278q Asus monitors. Not as simple as I figured.
2 I connected with the DVI cables. 1 I connected via dp-mini-to dp-full size cable I purchsed.
This will work provided I NEVER turn off the DP connected monitor. If I do, when I reboot, I must unplug the power, then unplug the dp cable. Replug the power, reattach the dp cable. Then the 'puter sees the monitor again. Grrr....
The only fix? I purchased an "active" dvi-dp adapter. The Passive adapters will rarely work. I did extensive forum trolling to confirm this after my problems.
It sucks, but it does work. If you don't go over 1920 x 1080, you can opt for a cheaper option as I did.
Google the Accell B087B-006B adapter(DVI to minidp) - It uses power from the DP plugin from your card. It is a single link option(that's what limits the res to 1920x1080) - as will be your monitors.
It is short -about 6"//15cm you will need a normal dvi cable like you use with your monitors now.
You plug the dvi cable into your monitor and this adapter, then this adapter to your video card. For me, it worked - they are like 30.00.
I can now power my monitor on//off as I want
The nice thing to remember once you get set up is download the latest catalyst. It has an eyefinity section that allows profiles to be set up. I have 4.
1 for just the single center monitor -simple web browsing and such.
1 for all 3 displays separate at 1920 x 1080 -great for office apps/browsing at the same time etc
1 for 3 screen eyefinity goodness. 5760x1080 with the peripheral vision is incredible. - I'll never go back! I only wish there were affordable monitor options for 1920x1200 resolutions.
1 for my plasma - I ran a 50' Hdmi from the card and grabbed an extra wireless keyboard and mouse for my living room. Works very well. Be sure to get a wireless with good range though.
Set them all up with the Alt & F9. Alt & F10 etc... The flexibility is nice, and why burn more power than we need eh?
Hope that helps, and good luck with your set up!
