Even with 14-inch and 16-inch screens, many MacBook users have already upgraded to two larger desktop screens at home or in the office—often using a laptop docking station to benefit from the extra video ports required for such a setup, plus extras such as multiple USB ports and Ethernet. Some hook up three monitors and there are even docks that support up to four external screens.
At CES, accessory maker Plugable unveiled the first docking station that can support five external monitors.
