DISPLAY PORT--What is DP/Display Port and why do I care?
This is a new 'open source' technology for transferring data between your computer and monitor.  It will be replacing DVI/VGA at some point in the not too distant future and as a far better technology if you currently have the ports on either device it's well worth taking advantage of.  And if you nave a video card which supports this technology adapters are available to connect your DVI/VGA monitor using these cables and technology.
