Solves Eyefinity Issue with Mini Active Display Port Adapter
In a nutshell, this cable is required for anyone who buys a ATI card supporting Eyefinity Technology and wants to run the extra (3rd) monitor that has only HDMI/DVI inputs
Card below is for the 3 monitor system. Remember, both DVI ports = 1 display each. DVI2 or HDMI maybe used for 2nd display. Mini Display Port is for 3rd display. Normal Mini Display Port cable can be used if the monitor has Mini Display Port connector ONLY. Otherwise, they must buy the above adaptor.
