How to setup Eyefinity to support three monitors on HD 5700/5800 series card?

Monitors are connected the following way: DVI-DVI-DisplayPort

Currently driver does not allow me to do this. If I click on the third monitor to extended it, I get message to disable other one.

I am using DisplayPort adapter to DVI, so I do not have native displayPort monitor. Might be that a problem?

This question has been asked before and already has an answer. If those answers do not fully address your question, please ask a new question.

What kind of adapter do you have? Apparently you need an active one, as explained here: – Snark Nov 6 '09 at 13:10
Verly likely passive I have this adapter: – Peter Stegnar Nov 6 '09 at 13:12

To establish Eyefinity on three monitors you can only do this to use DisplayPort connection. You can connect on DisplayPort only a native DisplayPort monitor or DVI/HDMI/VGA monitor with ACTIVE DisplayPort adapter.

All credits should go to the Snark, since he gave the crucial hint.

Are anyone knows where to order this adapter (to Europe)? – Peter Stegnar Nov 6 '09 at 13:50
ATI Response: Currently you must have a Display Port monitor with no adapters. Passive adapters do not work. Active adapters are being tested and some are working, once testing is complete a list of Active adapters should be available online. – Peter Stegnar Nov 6 '09 at 20:44
