That setup of yours looks quite comfortable!
I’m aiming to hopefully get 2, possibly 3 screens running off my ultrabook. I don’t mind shutting down the ultrabook screen either.
My ultrabook specs are:
Model: X520793AU – Dell XPS 13
Graphics: Intel HD Graphics 4400
I’ve got 2 USB3.0 ports and a micro display port to play with.
Oh! And my current OS is Ubuntu 14.0.1 LTS
