Frequently Asked Quesiton
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 DP, but when I plug in
the VGA, only VGA works? Why?
HDMI and DisplayPort (DP) are digital signals, but VGA is an analog signal. The
dock can only support one type of signal at a time. Therefore, HDMI and DP 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 a digital signal, and VGA is an analog signal. Only one type
of video signal can be supported at a time.
Can DP and VGA work together?
No. DP and VGA ports will not function simultaneously.
Can I use a Displayport video adapter with this dock?
Yes, DP++ allows DisplayPort to HDMI or DVI active adapters to function
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
Macbooks 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 charge, 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.
