Hi, I have AMD FirePro 2460 video card with 4 mini dp outputs & it came with 4 mini display port to DVI pigtail converters. http://www.newegg.com/Product/Product.aspx?Item=N82E16814195099 I have been using Four Dell U2412M High resolution monitors ( 1920x1200 )with it. Now one of the mini DP to DVI converter doesn't works so I have been searching for it & came across similar converters but they all say it is for Apple Cinema Display, to a Mac Pro (2009), Mac mini (2009), iMac (2009), MacBook, MacBook Pro, and MacBook Air etc. It looks almost identical to mine except the color, which is white & mine is Black. I am also not sure if mine is an active conveter or not. Apple's isn't. Here is what Apple's looks like : http://www.ebay.com/itm/Mini-Displa...=US_Video_Cables_Adapters&hash=item3f17998cea Here is what mine looks like except I am not sure i mine is active. http://www.ebay.com/itm/VISIONTEK-9...=US_Video_Cables_Adapters&hash=item27ca3c2faa So would Apple's adapter work in my Video Card ? Also how do I know if my adapter is active or Passive & what is the difference ? Thanks P.S. Scat & others who replied to my other post of using a second video card, If I can just get the right adapter, I don't want to take a chance on running a second video card.

Thank you Bolimomo. Very informative. AMD said it is Passive. They did not recommend the ones that state" it applies to Apple." as I posted the links. Active ones usually have Active written on them as following making it much easier to identify. Why can;t they do the same for Passive so that people who have never seen active can easily tell the difference. http://tommynation.com/displayport-dvi-adapters-explained/ From my experience with AMD, they don't make your life easier even when it comes to finding the right drivers. They refer firepro as firemv ins ome places & I have heard even pros getting confused about it.
I have mini display port & now I know I have a Passive adapter & it runs 1920x1200 on 24 inch monitors. I do have full size DP to DVI conveter & FirePro 2260 card. Now knowing what you said, I guess I am not going to try that video card with the current FirePro 2460. Any one having the experience of an original AMD Conveter going bad in less than 4 months of use ?
For $5 why not try it out? I had a few of those video cards and bought the white apple display port >> DVI adapters you listed and they worked fine for me - until I couldn't get modern drivers for the cards so I sold them all.
