@dskaram, have you got any thoughts on who is best to direct this towards?
This is holding back a knowledge worker roll out.

C720p doesn't support displaylink yet, it's WAI.
Status: WontFix (was: Unconfirmed)
@marcheu, would you be able to expand on C720p not supporting, and any intentions for it to be?

If there are any guidance docs for what is/isn't support regarding docking Chromebooks that you could point me towards that'd be greatly appreciated.
Toshiba Chromebook 2 is also performing the same. 

DisplayLink state support for:
Toshiba Chromebook 2
Acer Chromebook C740
