Q2. Does it support dual monitors 144Hz?
Q1. Why isn’t there a display image when connecting to the HDMI/DP ports?
Display Issues
If there is no display image after connecting:
1) Please check whether the driver has been properly installed.
2) Ensure the HDMI or DP cable works properly and the connection between the
devices is secure.
3) Ensure the HDMI and DP ports are in different “Display”. The HDMI and DP ports
in the same "Display" can't work together, please choose "HDMI 1+HDMI 2", "DP
1+DP 2", "HDMI 1+DP 2", or"HDMI 2+DP 1" to use.
4) Adjust the display resolution, as the monitor may support lower resolutions
than the docking station can support.
5) Ensure the correct input signal is selected on your monitor.
6) Restart your computer.
7) If the problem persists, try connecting to another monitor to ensure an image is
being displayed

Q4. What should I do if I restart my Apple computer and the HDMI/DP port does not display
properly even though images displayed properly after the first-time driver installation?
- 06 -
If after restarting your Apple computer the monitor doesn’t display properly:
Step 1: Enter the driver software "DisplayLink Manager" > Check the "Automatic
startup".
Step 2: Enter "System Preferences" > "Users & Groups" > "Login Items", Click the
"+" > select the "DisplayLink Manager".
Step 3: Restart the computer after adjusting the settings as detailed above. This

Q5. Is it normal for the connected monitor to display a black screen before projecting/
extending the correct screen after plugging/unplugging the docking station?
Yes. The monitor will display properly after it completes its EDID reading for screen
size, color properties, frequency range limits, etc. This usually takes about 10 sec-
onds.
Q6. What should I do if the display screen on my external monitor is black and flickers?
If your display screen is black and flickers after connecting to the docking station:
1) Try lowering the resolution and refresh rate.
2) Update the driver to the latest versions.
3) Try another HDMI/DP cable.
4) Restart your laptop.

Q7. Why does my screen display intermittent blanking, blurring, or color casting
when connecting to the HDMI/DP port?
Q2. Can I charge my devices via the USB-A port?
While it is possible to charge your devices this way, the USB-A port is primarily
used for data transmission, so charging speeds will be slow. If you want to charge
your devices, please connect to the PD power supply port.
If your laptop does not charge when connected to the docking station:
1) Ensure the external power supply is connected properly to the "PD" port and the
laptop is properly connected to the port.
2) Ensure the laptop’s USB-C port allows for power charging.
3) Disconnect then re-connect the dock cable to your computer.
Q1. Why doesn’t my laptop charge when attached to the docking station?
Charging Issues

There is a chance that the video signal has been distorted after it is transmitted to
the monitor. This issue can be caused by the cable, monitor, laptop, and/or the
docking station. To troubleshoot where the issue is exactly, try using a new HD-
MI/DP cable, another monitor, or another laptop to check whether the display is
normal.

In order to ensure proper performance from the docking station ports, please
download the driver before use, as the RJ45, HDMI, and DP ports are all managed
