FAQ
Why do I have no display when the dock is connected?
The USB-C port in your host laptop needs to support USB-C DisplayPort
Alternative Mode (DP Alt-Mode) for video viewing capability, otherwise the
docking station can only act as a data / Ethernet hub.
I have the dock connected with HDMI and MiniDP, but when I plug in the VGA,
only VGA works? Why?
HDMI and Mini DisplayPort (MiniDP) are digital signals, but VGA is analog
signal. The dock can only support one type of signal at a time. Therefore,
HDMI and MiniDP will work simultaneously, but VGA will work by itself.
Can HDMI and VGA work together?
No. HDMI and VGA ports will not function simultaneously as they are two
different signal types. HDMI is digital signal, and VGA is analog signal. Only
one type of video signal can be supported at a time.
Can MiniDP and VGA work together?
No. MiniDP and VGA ports will not function simultaneously.
Can I use a USB-C video adapter with this dock?
No. Video adapter converting from MiniDP, HDMI, or VGA to other type of video
interface will not work with this docking station.
When I connect to an Apple laptop, I can’t extend the display of my
desktop, why?
Apple’s Mac OS X does not support multiple display extension when on a USB-C
platform and/or connecting to a USB-C peripheral. USB-C Macbook with macOS
X 10.13.3 will only support one external display. USB-C Macbook with macOS X
10.13.4 will support two external displays in mirror mode. Thunderbolt 3
Macbook will support two external displays.
Why does the Ethernet connection not working on the docking station for my
Apple laptop?
Please check your Networking Preference setting (Apple menu > System
Preference > Network. The default Interface might set to Thunderbolt Bridge.
Click Add button “+” at the bottom of the list at the left. Click the
Interface pop-up menu, choose the “USB 10/100/1000 LAN” as network interface
and create a new
connection.
Can the dock charge my laptop?
No. The dock does not provide power to the connected computer or laptop. In
order for the connected computer or laptop to get charged, the computer needs
to be USB-C Power Delivery compatible and the dock needs to be connected to
an external USB-C AC power adapter.
FAQ
Can I use a bigger capacity AC power adapter with the dock to charge my
laptop?
Yes. You may use any available USB-C AC power adapter with the dock to charge
your laptop. When the USB-C AC power adapter is plugged into the docking
station, the docking station will consume maximum of 15W power when all ports
are connected and streaming data. The remaining power capacity will then be
directed to the connected laptop, with the maximum of 45W power.
Will this dock work when plugging into a Thunderbolt 3 port?
Yes, it will. The dock works when plugging into a Thunderbolt 3 port on your
computer. However, due to the supporting features by the operating systems,
the results will be different. For instance, Mac OS X supports only a single
display extension when using a USB-C peripheral, but Windows OS can support
multiple
display extensions.
Will this dock work when plugging into a Thunderbolt 2 port?
No it will not. The dock will only function when plugging into a USB-C port or
Thunderbolt 3 port. Please connect the docking station to your computer using
the tethered cable. The particular port on the docking station is not
compatible with Thunderbolt 2, but only Mini DisplayPort.
Will the dock work with Apple Super Drive?
No. The dock does not work with Apple Super Drive. The SuperDrive requires a
direct connection.
How many external hard drives can be connected to the dock?
Just one. The external hard drive must be connected to the USB port marked
with “BC 1.2” or Lightning logo. This USB port supports maximum of 1.5A power
and will be able to provide enough power to the external hard drive device.
My hard drive does not work when connected to the dock. Why?
Please make sure the external hard drive is connected to the USB port marked
with “BC 1.2” or Lightning logo. This USB port supports maximum of 1.5A power
and will be able to provide enough power to the external hard drive device.
Will this dock work with a Thunderbolt 2 display?
No. This dock’s Mini DisplayPort does not support Thunderbolt 2 display.
