Ensure that the latest BIOS and drivers for your computer and
the docking station are installed on your computer.

Make sure your computer is connected to the docking station
securely. Try to disconnect and reconnect the docking station
to the notebook computer.
•
Disconnect both ends of the video cable and check for
damaged/bent pins. Securely re-connect the cable to the
monitor and docking station.

Make sure the video cable (HDMI, mDP or DisplayPort) is
connected properly to the monitor and the docking station.
Ensure to select the correct video source on your monitor
(refer to your monitor's documentation for more information

may support higher resolutions than what the docking station is
able to support. Please see the

If your monitor is connected to the docking station, the video
output on your computer may be disabled. You can enable the

If only one monitor is shown, while the other is not, go to the
Intel Graphics Control Panel, and under Multiple Displays,
select the output for the second monitor.

If three monitors are connected to the docking station, then
the docking station will only support a maximum of two external
monitors. Refer to the User Guide of your docking station for
information on how to select and activate the desired monitors.
•
Try with a different monitor and cable that is known to be
good, if possible.
•
Reset the monitor to Factory Defaults. Refer to the User Guide
of your monitor for more information on how to reset the
monitor to factory defaults.

Ensure that the video cable (HDMI, mDP or DisplayPort) is
connected securely to the monitor and the docking station.

C cable and then removing the power adapter from the dock.
