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.
