External DisplayPort connection
The DisplayPort connection on the rear I/O supports DisplayPort 1.1 and functions as an output or as an input. As an output,
it can drive an external monitor with resolution up to 2560 x 1600 @ 60 Hz. As an input, an external source such as a
notebook can be connected and drive the Z1 G2's internal display. The HP MyDisplay application must be installed for
the input/output feature to function.
To switch from output mode to input mode or vice versa, use the key sequence "Ctrl+Shift+S+D".
Multiple displays support
The Z1 G2 supports multiple displays. The base unit supports two independent displays – one internal and one external
via the DisplayPort1.1a port on the rear I/O. With the optional Thunderbolt 2 module installed in the system, the Z1 G2
supports up to 4 displays when paired with NVIDIA professional graphics and up to 3 displays when paired with Intel HD
Graphics.
The Z1 G2 base unit supports:
• 1 internal display (2560 x 1440 @ 60 Hz max resolution)
• 1 display via the rear I/O (2560 x 1600 @ 60 Hz max resolution)
With optional Thunderbolt 2 module, the Z1 G2 support :
• 1 internal panel (2560 x 1440 @ 60 Hz max resolution)
• 1 display via the rear I/O (2560 x 1600 @ 60 Hz max resolution)
• 1 display via the Thunderbolt 2 port (4096 x 2160 max resolution)
• 1 display via the Thunderbolt 2 port (4096 x 2160 max resolution) - NVIDIA only
Thunderbolt 2 port can multi-stream up to 4 displays at native resolution with NVIDIA Professional Graphics. In this
scenario, other displays attached to the Z1 G2 are unavailable including the internal panel.
Thunderbolt 2 port can multi-stream up to 3 displays at native resolution with Intel HD Graphics. In this scenario, other
displays attached to the Z1 G2 are unavailable including the internal panel.
