Default Display Port to Dvi adapter Question

I currently have a couple of HP 48409-001 display port to dvi adapters and were wondering if these were active (will work with eyefinity) or passive. So far i can't find anything on google about that.

To my knowledge, for it to be active it would have to be drawing power from somewhere, like a USB port. If it's like a DVI->VGA adapter, I'd guess it'd be passive.

Googling that didn't help much, but anyways... If it has a USB connection on it, it's active. A smaller dongle (like one that looks like a straight cable, no "box") is passive and will not work with Eyefinity.

So these things are kinda useless for my desktop if my 5870 has 2 dvi connections and an hdmi connection (i know i cant use more then 2 without the third being an active dp one)

Pretty much... Unless you get and Eyefinity6 card at some point, which only comes with mini-DP to DP i think. Then you could use two of your adapters for the first two DVI outputs and then active ones afterward.

Do not use an active converter to DP. Usually ends horribly. If you want eyefinity bite the bullet and buy dp monitors, or one atleast.

You might find this an interesting read: Mal's Eyefinity Project (Info, Pics, Vids) (Using PASSIVE DP to VGA adapter!) - Overclock.net - Overclocking.net
