This selection is for two PNY Quadro T600 graphics cards. Each card has four Mini DisplayPorts for a total of 8 with two cards. These PNY T600 cards come with adapters that convert the Mini DisplayPorts to full size DisplayPort outputs. To use the card as intended you must have monitors with a DisplayPort input. If you don't have monitors with DisplayPorts then you must purchase separate adapters to convert the DisplayPort to either DVI or HDMI, but we don't recommend this approach. We recommend customers purchase monitors with DisplayPort inputs for best results.
