Question about Chromebook 11 - Slimport

Hi guys,

I recently bought a Chromebook 11 and I love it.

But one think I'm missing is a HDMI-Port.

So 'm thinking of buying a Slimport Adapter for it. Something like this:

I want to store the black big bulky think behind my table so I Need some kind of Extension for the micro-usb cable.

That's not the problem. But is Slimport a normal usb-connector or has it more Pins so the micro-usb Extension will not be able to Loop the hdmi-signal through?

I hope you know what I mean. And sorry for me english, I'm not a native speaker.
