Help to connect 3x1 on my HD 6970

[asufeld_ins]

Hello, I'm new to your and I am a bit hidden.
I explain my problem.
I own a 6970 HD graphics card and three VGA screen.
Two 17 "and 23 ".
The provision of such screen is:

17 "> 23"> 17 "

Having already in my possession three DVI to VGA for my screens.
I buy an adapter to fill diplay Port put two DVI connections on the screen and a screen on the mini-DP (with the cable supplied with the graphics card).
My two screen appears but not the third.
I read that I may need an adapter to be "active".
But I'm not sure what type of connector to transmit the analog signal to my monitors.

If not then I connect the third screen on the HDMI output? (with an HDMI to VGA)

Thank you for your reply and sorry for my English, I use a translator ...

Apparently you didn't read enough.

#1 You need symmetrical display setup for all three displays. PLP doesn't work on Eyefinity.

#2: Mixing resolutions doesn't work on Eyefinity.

#3: You need an active adapter for the third display.

#4: You can't use two DVI and a HDMI at the same time. The card is not equipped to push three legacy signals out without an active adapter on display three. Two displays go from DVI, third from mini-dp port.
