To extend the length of your Mini DisplayPort cable, you'll need an extension. Simply plug one end into the device and the other into the cable you want to extend. This cable gives you an extra 10ft to work with, plenty for most applications. This is helpful to reach monitors or TVs that are a distance away. Built to DisplayPort 1.2 standards, this meets the requirements for high-performance applications. The cable can even carry both an audio and video signal.
