Questions about this item

Does the 90 W Ultra Dock run loud or hot when it powers a ThinkPad all day?

The dock is a passive aluminium unit with no internal fan, so it produces no audible noise and stays cool under continuous 90 W operation.

What must I already own to use this dock with my ThinkPad?

You need a compatible ThinkPad from the L, T, W or X series listed — such as a T440, T460, X250 or W550 — that uses the rectangular side docking connector and ships with a 90 W or smaller AC adapter.

Will my older DVI or VGA monitors work alongside newer DisplayPort screens on this dock?

Yes — the dock provides one DVI-D, one VGA, one HDMI 1.4 and two DisplayPort 1.2 outputs, so legacy and current monitors can be connected simultaneously.
