Eyefinty only in duplicate-mode

[Dalavor]

Hello!

I´ve got a sapphire 5870 1GB, 3 LG DVI-monitors and the sapphire active-DP-to-DVI adapter. The three monitors are workling fine in extended-mode as long as I did not try to group them (what is necessary for Eyefinity, I think). When I do so, I´m always getting the Eyefinity duplicate-mode without the option to extend the desktop over the three monitors. I also think it has something to to with my CCC, because when I try follow the steps from the ATI-manual, I´m missing the point, where after the first step a wizard should start. Also, al lot of buttons are not workling without a restart from the CCC. I´m using the 10.1 drivers and CCC

I hope, someone can help me.

After you have grouped the monitors. Close CCC. Go to your desktop properties (in Vista) or screen resolution (in 7). See if you can more the resolution higher to the ideal setting, e.g. 5760x1080. That worked for me.

at 2:27 of this video, he starts through the steps for grouping, this is what worked for me:

Thank you for the quick response, but it doesn´t work. When I try to raise the resolution above the max. of one monitor, the Win7 resolutionmanger chrashes.

I found some other threads in this forum concerning the "grouping problem" and i tried some solutions they offered:

1. The mystery button below the ATI logo: can´t find it.
2. TH2G registry stuff prevent the CCC from working correctly: I used a regcleaner, no results
3. Switching the USB power supply: no effect.

Sorry, I know this video. Would be too simple, did not worked.

I believe the total grouping resolution is bound to the lowest common denominator. In my case I have smallish monitors:
1X Dell 2007WFP @ 1680x1050 (DVI), 2X Dell P2010H @ 1600 X900 (1 DVI, 1 Display Port)

When I use eyefinity my resolution is 4800 X 900 ( so my 2007WFP is forced to also be 1600 X 900)

@FalconX: 3x the same LG Monitor (1680x1050)

So, news from my "Eyefinity Duplicate" problem. My hope was that 10.2 would solve my problems, but it didn´t. The CCC runs more stable but with the same problems. I called the ATI support and they suggested to use the 9.12 drivers. I will try it soon.....

I have the exact problem. I cannot create an eyefinity group with any drivers above 9.12. I'm using a 5870 under Vista Ultimate 32-bit. I have tried uninstalling and using driver sweeper but I had to resort to going back to 9.12 to fix this issue.
