With this adapter you can connect a 59/60 pin graphics card connector to two monitors with DVI-I connectors.
Connect your nVIDIA or PNY, Quadro, or Matrox QID multiple display graphics cards using this DMS-59 cable with gold-plated contacts that provide full conductivity with no data loss. Many high-end work stations utilize multiple display graphics cards that only have a single DMS-59 or DMS-60 (also known as LFH-59 and LFH-60) connection. A breakout cable is necessary to convert this single connection into two more common monitor interfaces such as DVI or VGA.
