As a Dell user, I couldn't get my _Dell_ monitor working with _Dell_ E-Port Plus Port Replicator docking station (USD 219) when used with my _Dell_ E7240 laptop - in Linux (and this laptop has the option of selling with Ubuntu). Dell support were very patient and after 1 hour and docking station firmware update later (done via Windows obviously), it still doesn't work. Works fine in Windows (but only after firmware update). Now I use the "hunk of plastic" as a tilting platform to let the laptop vent exhale easier.
