IMPORTANT NOTICE
In order to use the full potential of the dock, it is important that the GPU
in the notebook supports DisplayPort 1.4 with DSC.
If the GPU in the laptop supports DisplayPort 1.4 without DSC, or DisplayPort
1.2, the dock will work, but with limitations in similarly maximum resolutions
of external monitors. See the SPECIFICATIONS section for more information.
DSC – short for Display Stream Compression – is a compression method that
allows for “visually lossless” video compression that allows for higher
resolution to be transmitted.
GLOSSARY OF TERMS
Interface / port / connector / input / slot – the place where two devices are
physically connected.
Controller – a semiconductor component (so-called chipset) in a notebook,
tablet, PC, ensuring the operation of one of the ports.
USB-C / USB Type-C – is a new symmetrical connector and standard introduced by
USB-IF in its USB 3.1 specification. Windows 10 (Microsoft), Mac OS X
(Apple) and Chrome OS and Android (Google) introduced native support for this
connector. It enables faster charging, power, so-called dual-role (not only
host but also a guest), support for so-called alternative modes – Alt Mode
(DisplayPort, MHL, Thunderbolt 3, Power Delivery), and error notification via
the device Billboard.
Alternative Modes (Alt Mods) – special modes for the USB-C connector that can
be supported. Currently the most popular are DisplayPort / DockPort, MHL, and
Thunderbolt. Devices with this feature of the connector and cable allow image
transfer while retaining the other functions of the connector (for data
transfer and charging via Power Delivery).
DisplayPort / DockPort Alt mode – this mode allows image transfer via USB-C
connector and cable.
USB Power Delivery (USB PD) – an optional feature of the USB-C connector.
A connector with this support can both charge and be charged and supports
loads from 10W to 100W (depending on profiles 1-5). In Windows 10, USB Power
Delivery cannot be applied to the former USB 3.0/2.0 A, B, and micro B ports.
USB 3.1 / 3.0 / 2.0 – standard for USB interface / port for connecting various
USB devices. Various USB devices can be connected to the docking station or
adapter using a USB Type-A interface. The USB Type B port is used to connect
the dock or adapter to a laptop, tablet, or PC.
HDMI/Display Port – A standard for a digital graphics interface/port used to
connect monitors and other graphic display devices.
Audio – a term for audio input (microphone) or output device (headphones/
speakers).

Note: 3 external monitors can only be connected when the laptop’s
internal screen is off. This is a limitation of the Intel graphics card.
The resolution, the frame rate, and the maximum number of connected external
monitors depend on the capabilities of the host PC/laptop.
CONNECTING TO THE LAN
The GLAN RJ-45 port is used to connect to an Ethernet network to a router
/switch / HUB and to the Internet, supporting speeds of 10 / 100 / 1000 Mbps.
USB DEVICE CONNECTION
Use the USB-C 3.1 port and USB-A 3.1 ports to connect a keyboard, mouse,
external drive, printer, and other peripherals, or use them to connect a HUB
for additional free USB ports. In this case, we recommend using a HUB with an
external power supply. In case the connected device is not charging or not
working, then plug the original/external USB-C power adapter into the power
connector of the parent laptop/Mac/smartphone/tablet or USB-C Power
The delivery port on the dock for power support.
NOTES ON USING THE USB-C PORT
Fully compatible devices/systems (Alt Mode & Power Delivery) USB-C is a new
standard with a great variety for use, while compatibility information is
complex. Some USB-C devices/systems support Alt Mode video output while others
do not. Some can be powered and charged via
USB-C Power Delivery, while others cannot.
Partially compatible devices (support either Alt Mode or Power Delivery, not
both)
Many current USB-C devices that support Alt Mode video output do not support
charging via USB-C Power Delivery. These devices still need their original
chargers for charging. Conversely, some USB-C phones and tablets can charge
via Power Delivery, but most do not support Alt Mode video output.
Incompatible devices/systems
The dock relies on new features introduced with USB 3.1 and as such, the USB-C
Power Delivery feature is not backward compatible with USB 3.0/2.0 for
charging older devices. Additionally, USB-A 3.0/2.0 (Male) to USB-C (Female)
converters are not compatible for connecting USB-C devices in the USB-A 3.0
ports of the dock. Most current phones and tablets with a USB-C port do not
support Alt Mode video output, and some do not support USB-C
Power Delivery. Check the device documentation or contact the device
manufacturer to verify suitability with these technologies.
CHARGING AND POWER SUPPLY
The adapter offers 1x USB-C Power Delivery port, which is designed to power
the connected “parent” device using the original/external AC adapter and to
charge devices connected via USB-C or USB-A 3.0 ports. The dock has the
ability to charge the host up to 85W via the standard USB-C Power Delivery
port. As mentioned above, some devices that support video output via USB-C
cannot be charged via USB-C. An original charger must be used for these
devices/systems.
The majority of problems with the docking station and the connected
peripheral devices can be solved by disconnecting the USB-C cable of the
docking station from the USB-C port of the PC / Mac/smartphone and
reconnecting after approximately 10 s.
USING IN WINDOWS OS
Advanced configuration for the graphics – after connecting the monitor and
clicking on the settings for “Image Resolution” in Windows, you can select the
monitor you want to use.
By clicking on the second monitor and moving it you can position this monitor
as required relative to the original monitor of your laptop/tablet
Now you can set Extend and Mirror mode:
- Mirror mode: on the monitor select the 2 nd Monitor, select Several monitors → Mirror this display → OK.
- Extend mode: on the monitor select the 2 nd Monitor, select Several monitors → Extend this display → OK.
Audio settings – this will allow audio settings in the Control Panels → Audio.
The Standby / Hibernate mode and the Video port – after the activation of the
laptop/tablet from the Standby / Hibernate mode the primary (original) monitor
is displayed, for this reason, we recommend using the monitor that is
integrated with the laptop/tablet as the primary monitor, so that you can log
on to the system again.
The Mirror mode – the additional monitor takes on the parameters of the
original monitor in the system, i.e., if you select the Mirror mode and the
original monitor resolution is e.g. 1280×1024 then the screen will be
displayed on the additional monitor with a resolution of max. 1280×1024 (even
if you set a higher resolution).
Pressing the keys „Windows“ + P you can also easily control the monitors – for
using a monitor in Win 10 you can select: Computer screen only, Mirror,
Extend, Second screen only.
USING IN MACOS X
WARNING!
Before installing, make sure you have the latest macOS for your device
installed on your Mac.
macOS does not support MST technology (2 or more monitors in extended mode).
No dock using USB-C DisplayPort Alt Mode supports connecting two or more
monitors in macOS, only Thunderbolt 3 docks and DisplayLink docks do.
A: After connecting the monitor, the screen on your Mac will glimmer, which is
a standard condition, after stabilization, it is possible to perform the
standard setting of the monitor here: System Preferences-Displays:
Click on Arrangement and in the default mode (Extended desktop) click on the
new monitor and drag it as necessary vis-à-vis the Mac monitor. If you select
Mirror displays the mode will change to Mirror (the resolution of the monitors
will be automatically adjusted according to their parameters and the highest
possible resolution will be set on both
monitors). By canceling the Mirror displays option you will return to the
Extended desktop mode.
Extended mode: The arrow indicates the possible position of the connected monitor vis-à-vis the Mac monitor.
Extended mode: In this mode, you can choose the Main monitor by dragging the
Menu Bar.
Mirror mode: This mode can only be used if supported by the Mac.
Click on Gather Windows: using this option you can choose the settings of the corresponding monitor – Scaled (offers available resolutions), Rotation (Standard, 90°, 180° and 270°) and Refresh rate (if offered). Below the following setting options are displayed. This may vary, depending on your monitor.
In Scaled mode click on the required icon, the resolution is displayed below
(which looks like this, 3008×1692 = [email protected])
Notes on using the docking station with monitors:
Working on a connected monitor while the Mac monitor is tilted is possible
with mains power (there is a partial limitation when using an HDMI monitor on
older versions of Mac). When battery power is applied, the use of the HDMI
monitor is limited by the Mac (in some cases, the procedure in the following
section can be used for display problems).
Most of the problems with screen refresh on a connected monitor after putting
the Mac to sleep, after using the screensaver, after restarting the Mac, or
turning the Mac off/on can be solved by disconnecting the USB-C cable of the
dock from the USB-C port of the Mac and reconnecting it after about 10
seconds.
B: After connecting other USB devices to the USB 3.0 port of the docking
station (USB external HDD, USB keyboard, USB mouse, USB HUB, USB graphics
adapter), these devices are used in the standard way. If the device does not
charge or does not work, then connect the original USB-C power adapter to the
USB-C port of the docking station to support power.
Most of the problems with the dock and connected peripherals can be solved by
disconnecting the dock’s USB-C cable from the USB-C port of the
PC/Mac/smartphone/tablet and reconnecting it after about 10s.
CHARGE
The docking station supports the charging of connected USB mobile devices such
as smartphones, e-book readers, media players, navigation devices, and
tablets. Simply connect the device to be charged with the original cable to
the USB port of the docking station. If the device does not charge, then
connect the original USB-C power adapter to the USB-C Power Delivery port of
the docking station to support charging.
AUDIO
The audio output device for listening via HDMI needs to be set/verified here:
System Preferences-Sound-Output – Set HDMI Audio Device.
The audio output devices for both headphones and monitor can be selected
in Open-Applications-Utilities-Audio MIDI.app – click on “+” at the bottom
left
– Create a Multi-Output Device and select the desired outputs from the options
on Multi-Output Device.
Most of the problems with the dock and connected peripherals can be solved by
disconnecting the USB-C cable of the dock from the USB-C port of the PC/
Mac/smartphone/tablet and reconnecting it after about 10s.
