According to this document (http://download.lenovo.com/pccbbs/options/tp_ultra_dock_sp40a02135.pdf) it should be possible to attach 3 (three) external monitors/displays to a docked Thinkpad.
It should also work with 1 Display in the DisplayPort , a second one in the other DisplayPort and the 3rd monitor in the VGA port, is that correct? (So all monitors connected to the dock, not to the Thinkpad)
This should definitely be possible with a Thinkpad W540 right?
Is it possible to use daisy-chaining (DisplayPort 1.2 MST) to get MORE than 3 external monitors running?
You should also definitely update this page http://support.lenovo.com/en_US/detail.page?LegacyDocID=MIGR-76617 or add a new one for the new docks and thinkpads where one can easily find out how many monitors one can connect and how.
