Second card inputs disabled. Crossfire 6950

Hello guys,
I recently upgraded my PC by buying a second graphic card.
Now am running successfully on Crossfire with 2 HD 6950
My drivers are all set up correctly. (running Battlefield 3 on medium with 70-100 fps on online mode)

But the problem is that i want to attach a 3rd monitor. (i already have 2)
My linked (second) card does not recognize the 3rd monitor.

:fou: The problem is also that if i put only one monitor on the second card it does not recognize it too. So the problem is not about the 3rd monitor but all in inputs of the 2nd graphic card are kind of disabled. :fou:

Please help me out and i appreciate you time:)

Greetings,
Nick

  1. In xfire the second card's outputs are disabled by default -- there's no way around it. If you want a third monitor you have to connect it to the top card via hdmi or one of the display ports. If your third monitor has a DVI plug, you will have to purchase an adapter to connect it to the card.

    I have 6850s in Xfires - ran into the same problem at first.
  2. Thanks for this info drjga,
    I have a passive DP adapter but is not working :(
    As i read i have to buy an active one that unfortunately costs around 100euros here.
    Thanks again!!!!!
  3. What are you using to connect the 3rd monitor ? Youll need to use a active adapter, such as this.

    I am using this and it works well: http://amzn.com/B004071ZXA

    Not sure if you can get in the UK though.
  5. abCasPeRR I am using an identical from other company but still I cannot enable all three monitors at the same time.

    I need to buy one USB powered, as i have read.
  6. Not necessarily. USB powered active adapters tend to be for those wishing to use a resolution higher than ~1080p.

    There are active adapters that are not powered via USB but still convert the signal (I'm using one now) for ~1080p and lower. These cost much less and work just as well.

    Such as http://www.amazon.co.uk/Accell-B087B-005B-UltraAV-Display-Certified/dp/B004071ZX0/ref=sr_1_2?s=computers&ie=UTF8&qid=1354143987&sr=1-2
  7. Thanks Spaniard!
    I will order asap :)

    I use the same works a charm. You do not need to buy a $100 one or one with a usb plug. This one works, passive will not.
  9. I just bought it! It has the logo of eyefinity so. Mines looks the same but it is a cheap one.
