Docking Stations
The HP Docking Station has three display output connectors and the HP Advanced Docking Station has five display output
connectors. The standard Docking Station has VGA, DVI, and DP connectors.
The Advanced Docking Station has VGA and four digital display output connectors (two DVI and two DP). Of those four
digital display connectors, only two may be used at a time (two DVI, two DP or one DP and one DVI). When used together
with the HP ZBook 15 G2, a maximum of five independent displays are supported. These five displays are the internal
panel plus four external displays connected to three display output connectors from the standard or Advanced Docking
Station, and the Thunderbolt™ 2
2
connector from the HP ZBook 15 G2.

DP 1.2 “daisy-chain” feature
DisplayPort v1.2 supports “Multi-Stream Transport”, which allows multiple video streams across a single DisplayPort
connection. This is commonly referred to as DP 1.2 “daisy-chain” feature where multiple displays may be driven by a
single DisplayPort connector.
The HP 2013 ZBook models, UltraSlim Docking Stations, Docking Station, and Advanced Docking Station support the
DisplayPort v1.2 “daisy-chain” feature. With the use of a DisplayPort 1.2 Hub or a DisplayPort 1.2 Display that supports
Multi-Stream Transport or “daisy-chaining”, a user may connect multiple external displays to a single DP connector on
either the ZBook or a supporting Docking station.
On all HP ZBooks, this capability provides for more flexibility on the type of displays that may be used. For example,
three DP displays may be connected with the use of a DP 1.2 Hub with all three DP monitors connected to the Hub, and
the Hub connected to the DP connector on the HP ZBook.
The maximum number of independent displays is increased to six with the use of DP 1.2 “daisy-chain” feature. This
requires Hybrid Graphics to be enabled, one monitor connected to VGA, and at least one daisy-chain connection on (A)
System DP, (B) Docking Station DP 1, (C) Docking Station DP 2.
