System architecture
The HP Z1 G2 Workstation features the Intel® Xeon® processor E3-1200 v3
family and 4th generation Intel® Core™ processors based on the new Intel
micro-architecture. Upgraded ME9 manageability, Intel-integrated USB 3.0 and
optional ThunderboltTM 2 features deliver improved productivity and stability.
New technologies
New Intel Processor micro-architecture
The Z1 G2 supports Intel’s next generation processors, featuring a new micro-architecture and a new instruction set
including AVX2 (Advanced Vector Extensions 2.0) and FMA (Floating-point fused Multiply Add instructions) that help
deliver faster compute performance, with low energy consumption. Both the latest Quad Core Intel Xeon processor
E3-1200 v3 Product Family and the 4th generation Intel Core processors (dual-core Intel Core i3 and Intel Core i5
processors) are supported. The Intel C226 PCH (platform controller hub) chipset complements the Z1 G2’s core architecture.
Intel Advanced Vector Extensions 2.0 (Intel AVX2)
The new Intel Advanced Vector Extensions 2.0 (Intel AVX2) extends the Intel Advanced Vector Extensions (Intel AVX)
with 256-bit integer instructions, floating-point fused multiply add (FMA) instructions, and gather operations.
The 256-bit integer vectors benefit math, codec, image, and digital signal processing software. FMA can improve
performance in face detection, professional imaging, and high-performance computing. Gather operations increase
vectorization opportunities for many applications. In addition to the vector extensions, this generation of Intel processors
adds new bit manipulation instructions useful in compression, encryption, and general purpose software.
Intel Data Protection Technology with AES-NI (Intel AES-NI)
The Intel Advanced Encryption Standard New Instructions (Intel AES-NI) are a set of Single Instruction Multiple Data
(SIMD) instructions that enable fast and secure data encryption and decryption based on the Advanced Encryption
Standard (AES). Intel AES-NI is valuable for a wide range of cryptographic applications, such as applications that perform
bulk encryption/decryption, authentication, random number generation, and authenticated encryption. AES is broadly
accepted as the standard for both government and industry applications, and is widely deployed in various protocols.
Next generation Intel® Active Management Technology
New features for Intel AMT 9.0 include:
•The Intel AMT network can now be enabled and disabled.
•Any configuration software can now synchronize the Intel AMT network time to coordinate with UTC.
•The ability to configure a headless platform remotely without the need for local user-consent has been added.
•Graceful restart support.
––ME8 only supported hard power operations, which can cause unpredictable system behavior. ME9 adds support for
graceful power operations that include shutdown / Reset / Sleep-deep / Hibernate to improve system stability.
Intel HD Graphics P4600
The new integrated Intel HD Graphics P4600 graphics engine provides professional entry graphics performance.
Available on Intel Xeon® processor E3-12x5v3 models, it comes certified for selected popular workstation applications.
The Intel HD Graphics P4600 graphics core integrated in Intel Xeon processors has 2 graphics cores and 20 Execution
Units and offers higher performance than the previous generation Intel HD Graphics P4000, which has 16 Execution Units.
The Intel HD Graphics P4600 supports Microsoft DirectX11.1, OpenCL 1.2 and OpenGL 4.0. It supports expanded media
acceleration features like full hardware decode and encode acceleration as well as advanced video processing features.
1866 MHz memory
The Z1 G2 supports standard DDR3 1866MHz ECC and non-ECC unbuffered DIMMs. 1.5V and 1.35V DIMMs are supported
and both run at 1.5V. This is the same technology as the HP Z230 platforms. The speed that the memory runs is
controlled by the processors, which is 1600MHz for this generation. Future processor refreshes are expected to support
1866MHz. Offering 1866MHz now allows a smooth transition for customers when the new processors are introduced.
4
Touch
The Z1 G2 offers a base unit with a touch panel option. The touch panel is a 27” panel with glass on glass ITO. It supports
10-point multi-touch with finger or capacitive stylus input. The accuracy of the panel is 1mm to each target and 10% jitter

Storage
Below is information on common storage features and new features specific to
the HP Z1 G2 Workstation.
Storage features
•3 - 6Gbps SATA connectors
– One for ODD
­­– Two for HDDs or SSDs
•Accommodates one 3.5” HDD (with 3.5” drive carrier)
Or
•Two 2.5” SFF HDDs or SSDs (with 2.5” driver carrier)
•2 - PCIe Mini Card connectors that auto configure as mSATA or mini-PCIe on power up
­­– One used for Wireless Lan
­­– One available for mSATA SSD or mini-PCIe card
•Toolless drive bay carriers. One drive carrier is supplied to support the configuration ordered. An optional drive carrier is available to support the alternate drive configuration.
­­– The 3.5” drive carrier accepts a single HDD and connects to SATA 0
­­– The dual 2.5” driver carrier supports two 2.5” HDDs or SSDs connected to SATA 0 and SATA 1
•SATA software emulation modes
– RAID1 (Default with greatest flexibility for most users)
­­– AHCI (Required when using SEDs)
– IDE (Legacy mode, limited functionality - Not recommended)
•RAID
­­– Two drive RAID 0 (Striped)
Or
­­– Two drive RAID 1 (Mirror)
•Intel® Smart Response Technology2 (SRT) OS Acceleration
•Intel Rapid Storage Technology drivers, RAID configuration Option ROM, and management GUI
(Graphical User Interface)
AHCI and RAID1 technology
The default SATA emulation mode on HP Workstations is RAID (RAID + AHCI) unless SEDs are installed. If SEDs are
installed, the SATA emulation mode will be set to AHCI. The SATA emulation mode can be changed in BIOS setup
Storage > Storage Options, but changing the mode is not recommended and can result in boot failure or data loss if the
SATA emulation mode is changed after the OS is installed or if a volume already contains data. Always back up your data
before making any storage system changes.
AHCI (Advanced Host Controller Interface)
AHCI is a technical standard developed by Intel for the hardware mechanism that allows software to communicate with
SATA (Serial ATA) devices. It is enumerated as a PCI device and transfers data between system memory and SATA devices.
AHCI provides many benefits over the legacy IDE (Integrated Drive Electronics) hard drive interface. Some of the
benefits include:
•Elimination of master/slave handling.
•Native Command Queuing (NCQ) that allows a SATA device to internally optimize the order of command execution
for increased performance.
•Trim command support for SSDs which keeps track of files that have been deleted but not erased on the drive.
This improves performance of the drive and helps extend the life of the SSD by preventing unnecessary writes.

Technical white paper | HP Z1 G2 Workstation
HP recommends Windows.
RAID (Redundant Array of Independent Disks)
RAID provides a method of combining multiple disks into a single logical volume to increase performance or create data
redundancy. There are two levels of RAID configuration that can be implemented on the Z1 G2 depending on the user’s
need for performance or redundancy.
RAID configurations supported are:
RAID0 – Creates a single volume that has data striped across 2 drives. The size of the volume is based on the size
of the smallest capacity drive times 2, (the number of drives in the RAID0 configuration). RAID0 is typically used to
improve performance or create a larger volume from smaller drives. There is no data redundancy or parity in a RAID0
configuration.
RAID1 – Creates a single volume that is a mirror image of two physical drives. The size of the mirror is limited by the
smallest drive used in the RAID1 configuration. This configuration provides data redundancy protection against a single
drive failure, does not use parity, and does not improve performance.
RAID+AHCI
RAID+AHCI provides most of the benefits of AHCI with the added flexibility of RAID for configurations needing
performance or data redundancy. Even if you don’t use RAID today, setting the SATA mode to RAID (RAID+AHCI)
makes your system RAID ready for the future. RAID (RAID+AHCI) is the preferred mode and default storage
configuration SATA mode set in HP Workstation BIOS.
Acceleration with Intel® Smart Response Technology2 (SRT)
The Z1 G2 contains technology for using a Solid State cache drive (SSD) to accelerate the storage system. Moving
frequently accessed data to the SSD can improve overall system performance, increase read/write access speeds, and
reduce system start-up times. As the system is used, the driver learns which data is frequently used and moves it to the
cache SSD for quick access later.
Requirements for SRT
The Z1 G2 ships with processors, RAID controllers, and RAID-Ready BIOS capable of supporting SRT. The following
configuration specific requirements must also be met. The acceleration options will only be available in the GUI if all of
the requirements are met.
•Acceleration capable device. This must be a single HDD or single volume RAID volume consisting of only HDDs.
Single SSDs or RAID volumes that include one or more SSD cannot be accelerated. Matrix RAID volumes
(more than one RAID volume on the same set of HDDs) cannot be accelerated.
•Cache Device. The cache device must be a Solid State Drive (SSD) with a minimum available capacity of 18.6GB.
The SSD can be a standard 2.5” SSD connected to one of the SATA ports, or an mSATA SSD connected to one of
the mini-PCIe connectors. The maximum cache size is 64GB, so if a 256GB SSD is used as the cache device, the maximum cache size of 64GB could be set leaving 192GB available as a data volume.
•The OS must be installed on the device being accelerated. The OS cannot be installed on the SSD or RAID
containing SSDs.
•The SATA mode in BIOS must be set to RAID mode. SRT is not supported when SATA mode is set to AHCI or IDE
mode in BIOS.
•At least 10MB of unallocated space needs to be available at the end of the HDD or RAID volume being accelerated.
This space is used to store information and status of the cache configuration. This space only needs to be made
available the first time SRT is setup. During the setup process, SRT consumes the space and hides it from the
operating system. If you used Disk Manager to shrink the last partition on the HDD and create exactly 10MB of
unallocated space, after SRT configuration the complete 10MB of space will no longer be visible in disk manager.
If you already had significantly more than 10MB of unallocated space available at the end of the HDD, you will see
the unallocated space reduced by approximately 5MB to 10MB.
•The system cannot include a recovery volume unless 10MB of unallocated space is reserved at the end of the drive.
Recovery volumes are typically configured such that the remaining unpartitioned space at the end of the OS drive is consumed, which leaves no space for SRT configuration data.
11
Technical white paper | HP Z1 G2 Workstation
HP recommends Windows.
Other limitations when SRT is enabled.
•Only one disk or RAID volume can be accelerated per system.
•Once a RAID volume is accelerated, a second RAID volume cannot be added to the same array.
•Matrix arrays (more than one RAID array sharing the same set of drives) are not supported.
•Once a solid-state drive is configured to be used as a cache device, the option to create a recovery volume is no
longer available.
•The maximum number of volumes allowed in the storage system is four. If the system has more than 4 volumes, the RST application will not display options to accelerate.
Mini-SATA (mSATA) Solid State Drives
The Z1 G2 supports full length mSATA SSDs installed in the PCI Express Mini Card connectors. At boot, the mSATA card
will be detected and the interface will automatically be configured as a 6Gbps SATA port.
The mSATA SSD will appear in the option ROM (when multiple drives are connected to the systems SATA ports), and will
appear in the Intel® RST software GUI as any other SSD.
The mSATA SSD can be used for:
•OS Drive
•SRT* cache
•SRT* cache and data (256GB SSD > 64GB SRT cache + 192GB data)
•RAID with another drive for data protection
* Use with SRT is subject to the requirements and limits listed in the SRT section above
CAUTION: mini-PCIe memory cards and mSATA SSD cards look similar. Mini-PCIe memory cards require custom drivers
provided by the mini-PCIe card manufacturer. If you install a mini-PCIe memory card in your system, you will be able
to see the device in the Windows device manager, but the card will not function without custom drivers. The mini-PCIe
memory card is not compatible with mSATA and is not supported.
Frequently asked questions.
•I installed a Solid State Drive to use with SRT, but I don’t see any option for acceleration.
The most common issues that prevent SRT functionality are:
– Your OS is also on a Solid State Drive? You can only accelerate HDDs.
– If your installed OS consumes the entire disk and did not leave room for SRT configuration metadata, the option to
accelerate will not be available. Use disk manager to shrink the last partition on HDD by 10MB. You should then see
10MB of unallocated space. After SRT setup this unallocated space will not be visible in disk manager.
– RAID mode is not set in BIOS. SRT uses RAID functionality. RAID mode must be set as the SATA mode in system BIOS
for SRT to function. (Do not change from AHCI to RAID mode if your OS is already installed. Changing SATA emulation
modes after OS install may make the system unbootable because the correct drivers for the new mode are not installed
in the OS.)
– The system contains a Self Encrypting Drive (SED) and has encryption active. Software applications that interact with
SEDs require that the SATA mode be set to AHCI. SEDs and SRT functionality are not compatible. (Do not attempt to
change SATA modes if your system contains a Self Encrypting Drive. Changing modes may result in failure to boot and
unrecoverable loss of all data.)

ThunderboltTM 2 technology overview
The Thunderbolt 2 module provides transformational high-speed, dual protocol
I/O that enables unmatched performance over current I/O technologies with
20Gbps bi-directional transfer speed. It provides flexibility and simplicity by
supporting both data (PCIe) and video (DisplayPort) on a single connection that
can daisy-chain up to six devices.
Thunderbolt3 2 technology overview
Thunderbolt 2 technology key features
The Z1 G2 provides Thunderbolt 2 technology via an optional module that replaces the ODD in the side I/O bay.
This module uses the Intel® DSL5520 Thunderbolt 2 controller and provides two Thunderbolt 2 ports when used
with NVIDIA professional graphics. When pairing the Z1 G2 Thunderbolt module with Intel HD Graphics, one
Thunderbolt 2 port is available.
Thunderbolt technology dramatically increases the data transfer rate enabling faster backup, editing and file sharing,
significantly reducing the time to complete key tasks. Thunderbolt technology was specifically designed with inherently
low latency and highly accurate time synchronization capabilities. These features enable extremely accurate audio and
video creation, playback and editing that no other standard interconnect technology can match.
Each Thunderbolt 2 port provides:
•20Gbps bi-directional data transfer
•Data & Video on a single cable with dual-protocol PCI Express and DisplayPort
•Daisy-chaining of up to 6 devices
•Uses native PCIe and DisplayPort protocol software drivers
•Power over cable for bus-powered devices
•Compatible with existing DisplayPort devices
•DisplayPort 1.2 capability with Multi Stream Transport (MST) support that enables the transport of multiple
A/V streams over a single connector
•Maximum 4096 x 2160 resolution at 60 Hz (8-bit display) or at 30 Hz (10-bit display) to a single display
•Maximum 3840 x 2160 resolution at 60 Hz (8-bit display) or at 30 Hz (10-bit display) across 4 displays

Protocol architecture
Thunderbolt technology is based on a switched fabric architecture with full-duplex links. Unlike bus-based I/O
architectures, each Thunderbolt port on a computer is capable of providing the full bandwidth of the link in both
directions with no sharing of bandwidth between ports or between upstream and downstream directions. The
Thunderbolt protocol architecture can be abstracted into four layers as shown in Figure 5.
Figure 5. Thunderbolt Technology Architecture
Application specific
Protocol Stacks
PCle
DisplayPort
Common Transport Layer
Electrical/Optical Layer
Connector and Cable
ThunderboltTM technology
A Thunderbolt connector provides dual protocol bi-directional 20Gbps of bandwidth enabling the connection to
Thunderbolt products or to DisplayPort devices. Compatibility to DisplayPort devices is provided by an interoperability
mode between host graphics controllers and DisplayPort products. If a DisplayPort device is detected, the Thunderbolt
controller will drive compatibility mode DisplayPort signals to that device (e.g. native DisplayPort signaling). Support for
DisplayPort also enables easy connectivity to other display types, such as HDMI, DVI or VGA with an adapter.
Thunderbolt cables may be electrical or optical; both use the same Thunderbolt connector. An active electrical cable can
be used for connection up to 3 meters in length and can provide up to 10W of power delivered to a bus-powered device.
An active optical cable would be used for connections greater than 3 meters in length and up to 100 meters in length.
Optical cables do not provide power for bus powered devices.
The Thunderbolt protocol physical layer is responsible for the link maintenance including hot-plug detection and data
encoding. The physical layer introduces minimal overhead and provides a full 20Gbps per channel of usable bandwidth to
the upper protocol layers. The Thunderbolt protocol architecture transport layer includes a high performance, low-power
switching architecture, a highly efficient, low-overhead packet format with flexible QoS (Quality of Service) support that
allows multiplexing of bursty PCI Express transactions with isochronous DisplayPort communications on the same link.
DisplayPort and PCI Express protocols are mapped onto the transport layer. The mapping function is provided by a
protocol adapter which is responsible for the efficient encapsulation of the mapped protocol information into transport
layer packets. Mapped protocol packets between a source device and a destination device may be routed over a path that
may cross multiple Thunderbolt controllers. At the destination device, a protocol adapter recreates the mapped protocol
in its native format. The advantage of protocol mapping in this way is that Thunderbolt technology enabled devices
appear as PCI Express or DisplayPort devices to the operating system enabling the use of standard drivers.
Controller architecture
A Thunderbolt controller is the building block used to create Thunderbolt products. The Thunderbolt controller contains
a high performance cross bar Thunderbolt protocol switch, up to two Thunderbolt ports, up to two DisplayPort protocol
adapter ports, and a PCI Express switch. A Thunderbolt controller acts as a junction in a daisy chain of Thunderbolt
products, as well as a point of entry and an exit point for the encapsulated interconnect protocols (PCI Express and
DisplayPort).
The host Thunderbolt controller is responsible for managing the connections in the Thunderbolt daisy chain, plug
events, and wake events. The Thunderbolt controller high performance cross bar switch routes traffic in the converged
I/O domain between the PCI Express input, the multiple DisplayPort inputs and the multiple output channels. The high
performance crossbar distributes packets to the protocol mapping engines or the downstream ports enabling maximum
flexibility.

Performance
The Z1 G2 Thunderbolt module implements Thunderbolt 2 technology. Thunderbolt 2 technology provides 20Gbps
of combined bandwidth in each direction for both inbound and outbound PCI Express and DisplayPort protocols. The
20Gbps bandwidth is capable of transporting DisplayPort 1.2 4k video streams as a single stream or four 1920x1080 HD
streams via the MST protocol. 4k video capture input can be achieved simultaneously with 4k DisplayPort output by using
Thunderbolt’s integrated PCI Express capability.

Audio features
The HP Z1 G2 All-in-One form factor provides additional audio features not
present in traditional tower workstations. Most notable are the high quality
stereo speakers and the integrated microphone array.
The Z1 G2 implements DTS Studio Sound which provides audio enhancement
features. These digital signal processes augment the sound stage, creating an
immersive audio experience. The DTS Studio Sound User Interface (UI) is
available to customize/optimize these features. It is supported on Windows 7
(32 and 64-bit) and Windows 8.1 (32 and 64-bit).
DTS Studio Sound provides listeners with wider stereo sound, by expanding the
size of the audio image in both the horizontal and vertical sound field. DTS
Studio Sound brings out rich sounds and nuances buried in the recorded or
streamed multimedia content, creating a more natural audio experience with
clearer definition, dynamic center control, and deeper bass.
DTS Studio Sound UI
The DTS Studio Sound UI can be opened from the Taskbar or from the Control Panel. There are four tabs within the DTS
Studio Sound UI:
•Volume
•Listening Experience
•Recording Experience
•Advanced Settings
Figure 6: DTS Studio Sound UI Volume tab
Active devices and gain can be selected in the Volume tab (Figure 6). DTS enhancements and EQ can be adjusted in
the Listening Experience tab (Figure 7). Jack Configuration and re-tasking is found in the Setup tab (Figure 8). Controls
for the integrated microphone array are found in the Recording Experience tab (Figure 9). The Advanced Settings tab
(Figure 10) has options for Power Saving State, a shortcut to the Sound control panel, and a Reset button to restore all
audio settings to default.

Listening experience
The DTS Studio Sound UI contains many controls for optimizing the audio experience on the Z1 G2. These controls have
been pre-set to sound best for a wide range of audio content. However, depending on the audio content or personal
preference, adjustment may be desired. After the controls are adjusted, it is always possible to return to the original
settings: use the Reset button found in the Advanced Settings tab.
There are two portions of controls in the Listening Experience tab: the Graphic Equalizer and DTS Studio Sound Audio
Enhancements. The Graphic Equalizer adjusts the gain of different frequency bands in the audio spectrum. The default
pre-set is a flat (ideal) frequency response. There are many other pre-sets for various music genres. Or the user can
define a custom Graphic EQ pre-set.
Figure 7: DTS Studio Sound UI Listening Experience tab
The Graphic EQ should not be considered as a volume control. The result of pushing all the sliders to maximum gain
could be increased audio distortion. This is especially true for the low frequency bands (125Hz and lower). If extra bass
is desired, either use the Bass slider in Audio Enhancements or connect an external subwoofer (to the orange jack in the
rear I/O panel). The Z1 G2 is acoustically tuned to be used with the HP Pulse Subwoofer.
The Audio Enhancement portion of Listening Experience tab controls the DTS Studio Sound effects. These are
psychoacoustic effects produced by digital signal processing. These effects can be enabled/disabled with the checkbox
next to “Audio Enhancement.” These effects can be adjusted separately for three modes: Music, Voice, and Movie. These
effects apply to the internal speakers, headphones, and line-out.
Descriptions of the DTS Studio Sound effects are as follows:
Bass
Increasing this value will provide a greater TruBass effect (more low frequency information). Decreasing this value will
provide less of an effect. This is a psychoacoustic effect (not the same as increasing the gain of the low frequency bands
in the graphic equalizer).
Definition (Treble)
Increase the value of this control if the perception of clarity and acoustic space needs improvement. Decrease the value if
the high frequencies are too sharp.
Center
Center affects the volume of the center channel. Increasing this control will result in a louder center channel image.
Decreasing it will lower the center volume.
Space
Space affects the apparent width of the stereo image. The higher the value of this control, the louder the stereo space
effect.
Focus
Focus affects the apparent vertical position of the sound. Increasing this control will raise the elevation of the
soundstage. Decreasing this control will lower the elevation down to the physical level of the speakers.

Also found in Listening Experience is the Setup tab. This gives a visual indication which jacks have devices plugged in.
The right microphone and rear line-in jacks can be re-tasked as alternate functions. Right click on the jack icon in Setup
tab to select the function.
Figure 8: DTS Studio Sound Setup tab
Recording experience
These effects apply only to the integrated microphone array (not to external microphones). The features are as follows:
Noise Cancellation
Cancels background noise
Acoustic Echo Cancellation (AEC)
Removes audio coming from the speakers
Beam Forming
Removes some of the sounds outside of a 30 degree cone, starting at the microphone array

Advanced settings
There is a Power Savings State which allows the user to define a delay before the system turns off the audio analog
power supply. This delay triggers once audio playback has ceased. The system recognizes when playback ends/begins
and automatically turns audio power off/on accordingly. When Power Saving State is enabled, runtime beeps are
disabled, but diagnostic beeps during boot are not affected. This audio Power Saving State has no effect on other OS
or BIOS power savings states.
Device Notification enables the jack monitor for side microphone and rear line-in. These jacks can be re-tasked to
alternate functions.
Multi-Streaming allows two distinct audio streams to be played simultaneously. This is useful for making conference
calls and playing music at the same time.
Figure 10: DTS Studio Sound UI Advanced Settings tab
The Z1 G2 takes the AiO audio experience to the next level: high quality hardware combined with DTS Studio Sound
algorithms result in an intense and immersive audio experience. The Z1 G2 was painstakingly tuned for optimum
acoustic performance. Also, the intuitive and simple DTS Studio Sound UI allows the user to fully customize their system
to their own preferences. The final result is an audio system destined to impress!

Battery charging technology
The USB Battery Charging Specification v1.2 (USB BC 1.2*) defines a special USB
port that will allow some devices to charge (tablets) and other devices to charge
faster (cell phones). This USB port is called a Charging port and supports at
least 1.5A of charging current under normal operation, sleep, hibernate, and
shutdown modes. The USB charging port can be identified by the lightning bolt
icon shown below.
Charging Port icons
For USB 2.0 Battery Charging Ports
For USB 3.0 Battery Charging Ports
Charging modes
A USB Port that supports Battery Charging can be placed in to one of three modes:
•Standard Downstream Port (SDP)
SDP allows the USB port to work as a traditional USB port that supplies 500 mA (USB 2.0) or 900 mA (USB 3.0). USB communication is supported in this mode. This mode will allow some devices to charge slowly.
•Charging Downstream Port (CDP)
CDP allows the USB port to follow the USB BC 1.2 Specification. This allows the USB port to supply up to 1.5A
for charging and provides USB communication simultaneously in this mode.
•Dedicated Charging Port (DCP)
DCP allows the USB port to follow the USB BC 1.2 Specification and provides up to 1.5A. Dedicated Charging Port does not support USB communication.

DisplayPort bussing
The HP Z1 G2 Workstation was designed using DisplayPort interface bussing to
provide the necessary capabilities to deliver greater display resolutions (up to
4Kx2K), better color depths, higher data transfer rates and support for HD
video-audio formats. DisplayPort supports compatibility to VGA, DVI and HDMI
with use of DisplayPort adapters.
DisplayPort uses a more reliable connection method to improve signal
connectivity with easy mate/unmating capability.

Technical white paper | HP Z1 G2 Workstation
Graphical Sources
The Z1 G2 DisplayPort bussing provides the capability to use 1 of the 2 Internal Graphical Sources to drive up to
4 displays (Internal LCD panel and 3 external monitors) simultaneously, and the capability of an External Graphical
Source to drive the Internal LCD panel.
Internal Graphical Sources
Several of the Intel® CPUs offered on the Z1 G2 support Intel integrated processor graphics, such as Intel HD Graphics
P4600, Intel HD Graphics 4600 or Intel HD Graphics 4400. The Intel HD Graphics engine provides up to 3 DisplayPort
1.2 source outputs to drive a maximum of 3 displays simultaneously. The DisplayPort assignments are the Internal LCD
Panel, the Rear DP port and the Thunderbolt 21 module’s port 1.
The NVIDIA Professional Graphics card in the MXM slot provides up to 4 DisplayPort 1.2 source outputs to drive a
maximum of 4 displays simultaneously. The DisplayPort assignments are the Internal LCD Panel, the Rear DP port, the
Thunderbolt 2 module port 1 and the Thunderbolt 2 module port 2.
Due to the functional operation of the DisplayPort bussing only one Internal Graphical source can be used at any time
and it is based on system configuration and the detection of NVIDIA MXM Graphics card presence. The table below lists
Internal Graphics Source based on system configuration.

External Graphical Source
The Z1 G2 can be used as a large display with video input through the Rear DP port from an External Graphical Source.
This External Graphical Source is supplied by an external system such as a Workstation, or a Workstation Notebook, or
Desktop system with a DisplayPort output. The DisplayPort output from the external system must be connected to the
Rear DP port on the HP Z1 G2 with a DisplayPort cable only.
To enable graphics from external source, the Z1 G2 must be running a Windows OS with HP My Display software
installed. The external system can be running any operating system but must support driving a DisplayPort output.
Once both systems are running and connected via DisplayPort cable, a key sequence of “CTRL-Shift-S-D” entered on the
Z1 G2 keyboard will switch the Internal LCD panel from displaying the Internal Graphics Source to the external system’s
graphics.
Another iteration of the key sequence followed by a space bar press on the Z1 G2 keyboard will return the Internal LCD
panel displaying the Internal Graphical Source.
When the External graphical source drives the Internal LCD panel, all Z1 G2 power and sleep controls are disabled.
DisplayPort outputs
Internal LCD panel
The Internal LCD panel has a native resolution of 2560x1440 @ 60Hz, so this DisplayPort port only needs to be
configured as DP1.1a and is driven/controlled by any 1 of the 3 graphical sources. The graphical source should be able to
change the resolution of Internal LCD panel, based on the Internal LCD panels EDID and Graphical source driver.
Rear DisplayPort
The Rear DP Port uses a standard DisplayPort receptacle with latching and is configured as DP1.1a. This port has the
capability of being used as a source to drive a monitor to max resolution of 2560x1600 @ 60Hz. Additionally this port can
be used as an input from an external graphical source to drive video on the internal LCD panel, the rear DP port drives
DisplayPort 1.1a signaling out to an external monitor. The rear DP port supports all interfaces to a monitor --DisplayPort,
VGA, DVI, HDMI and dual-link DVI-- via DisplayPort cables and adapters (DP2VGA, DP2DVI, DP2HDMI and DP2DLDVI).
Thunderbolt DisplayPorts
The Thunderbolt 2 module ports 1 and 2 are mini-DP ports and are capable of sourcing DP1.2. Since the Intel HD
Graphics engine only has 3 DisplayPort outputs, only Thunderbolt 2 module Port 1 is available. If NVIDIA Professional
Graphics card is configured in the system, both Thunderbolt 2 module ports 1 and 2 are available. The Thunderbolt ports
support all interfaces to a monitor --DisplayPort, VGA, DVI, HDMI and dual-link DVI-- via a mini-DP to DisplayPort cables
or mini-DP to DisplayPort adapter plus the appropriate adapter (DP2VGA, DP2DVI, DP2HDMI and DP2DLDVI).
