Trouble Shooting

Monitors not Working
This docking station uses a technology called DisplayPort Alternate Mode (often referred to as DP Alt-Mode) to send your computer’s video signal to connected monitors. If the monitors connected to the docking station are not working, your computer’s USB-C port may not support DP Alt-Mode.
Please check with your computer’s specifications to see if your computer’s USB-C port supports DP Alt-Mode. All USB-C ports look physically the same and some manufacturers label their USB-C ports to indicate if they support DP Alt-Mode or not, however many do not have any labels at all. Your owner’s manual or the  manufacturer’s website will help you find if your computer’s USB-C port supports DP Alt-Mode. If your computer’s USB-C port supports Thunderbolt 3 or Thunderbolt
4, then it also supports DP Alt-Mode and will work with this docking station.
Connection Issues
If you are experiencing connection problems, unplug the docking station from your computer and replug or unplug and replug the connection that is experiencing problems.

* Computer’s USB-C port must support DisplayPort 1.4 with DSC
