I know DisplayPort best as all of the fun getting a 6 way eyefinity setup working. Well now it might make your monitor a laptop dock thanks to AMD and Texas Instruments DockPort. Yep, I like this idea. Anandtech reports that it has been adopted officially as a DisplayPort extension.
With DockPort the VESA is initially targeting a slightly different series of use cases than what Intel and Apple have done with Thunderbolt, both for technical and pragmatic reasons. Whereas Thunderbolt is being used to supersede USB 3.0 in some cases, as DockPort is based on USB 3.0 there’s little need to supersede USB 3.0 as far as data connectivity is concerned. Rather DockPort will be focused on single-cable connectivity – and as implied by the DockPort name – as a docking interface for tablets and laptops. The latter in particular owing to the fact that DockPort carries power alongside its data and display components.
