Output configuration is Dual Link DVI-I supporting VGA with dongle supplied, HDMI and two mini-DisplayPorts, allowing a wide range of monitor types to be connected. AMD's multi-monitor SLS technology, Eyefinity is supported. For enthusiasts wishing to maximise performance of this graphics card, the latest version of the SAPPHIRE overclocking tool, TriXX supports this technology and is available free to download from the SAPPHIRE website.
