Help setting up eyefinity with xfire HD7970?

[Sega Mega Dave]

Hi Guys,

I have 3 Dell U2312HM monitors and I'm trying to setup eyefinity on my crossfire 7970's but I can only get 2 monitors to work.

Now I know I am doing something silly so if one of you lovely gentleman could guide me it would be much appreciated.

All the monitors work but soon as a third goes in one of the goes off with no signal.

Connections on the back are 2 display port, hdmi and dvi.

Now i have tried the following and no joy:

1 DVI, 1 HDMI (using adapter that came with card), 1 DP (using adapter that came with card. meant to be active)

1 DVI, 1 DP (adapter), 1 DP (adapter)

1 HDMI, 1 DP (adapter), 1 DP (adapter)

None of the above let more than 2 monitors work.

The monitors connections are DVI, VGA, Display Port. Unfortunately i don't have any DP to Mini DP cables so can't test that way yet.

So gents what am i doing wrong?

Thanks,
Dave

From what i have read, if i used DVI to all monitors and then connected using DVI, a dp adapter and a hdmi adapter to the card it should work but nope.
