| Only use the original Thunderbolt 3 cable, which comes with your dock!|
USB Type-C cable is not compatible, as USB Type-C does not support all features. For details please see below comparison
Thunderbolt vs. USB Type-C comparison:
The power delivery indicator on the front panel glows white when the computer is being supplied power from the dock.
HDMI and DisplayPort output on dock requires computer with DisplayPort over USB Type-C support. Please contact your computer manufacturer for more information.
Some computers might not immediately recognize that the dock is connected upon start-up. This is related to the computers BIOS start up sequence but not a malfunction of the dock. If this occurs, do the following:
1. Turn off the computer.
2. Disconnect the dock from the computer and wait approximately 30 seconds.
3. Turn the computer back on.
4. Connect the dock to the computer once the operating system of the computer has loaded.
Disconnecting/Undocking your computer

Configuring Audio Ports
You can play back or record audio either through the audio port of the dock or the docked computer. However, you cannot use the audio ports on the docked computer and on the dock at the same time. Upon connection, the audio port on the dock might become enabled and the audio ports on the computer disabled. When you undock the computer, the audio ports on the computer are re-enabled automatically. To change the default settings, you might need to adjust the audio settings in Windows manually, as described in this section.
Configuring Video Ports
The dock provides the following video ports:
HDMI for connection to HDMI (using the HDMI cable which is not provided) interface monitors.
DisplayPort for connection to DisplayPort (using the DisplayPort cable which is not provided) interface monitors.
VGA monitor port for connection to VGA (using the VGA cable which is not provided) interface monitors.
Mini DisplayPort for connection to Mini DisplayPort (using the Mini DisplayPort cable which is not provided) interface monitors.
Note: Upon connection, the video output ports on the dock become enabled and the video output ports on the computer become disabled. When you disconnect the dock from the computer, the video output ports on the computer are re-enabled automatically.
Connect the monitor cable (not provided) to the video output port on the dock and the external monitor. This cable can be connected and disconnected any time without disconnecting the dock from your computer. You can customize the video settings of the dock. See Adjusting Video Settings section for more information (contained in user's manual).
How Standby/Sleep/Hibernation Mode Affects Devices Attached to the dock
The external monitor connected to the dock goes blank if the computer enters standby/sleep/hibernation mode.
When in Duplicate mode, the external monitor retains the settings it had previoulsly when the computer resumes from standby/sleep/hibernation mode.
When in Extend Mode, windows that were previously on the external monitor might appear on the built-in display of the computer when the computer resumes from standby/sleep/hibernation mode. You might need to reposition the windows by dragging them to the external desktop again.
Also, if the external monitor is in Extend mode and the computer requires you to log in after resuming from standby/sleep/hibernation mode, the login screen appears on the primary computer display, not the external monitor. This is consistent with Windows Operating System standards.
If another device is connected to a port on the dock and the computer goes into standby/sleep/hibernation mode, that device does not function.
