The Thunderbolt 4 Dock’s Thunderbolt 4 downstream port supports up to 8K@30Hz resolution. If you cannot get your monitor working through this port, it could be due to an issue with the connected laptop, the connected cable, the monitor, or the dock itself.
Here are some troubleshooting tips that may help identify and resolve the problem.
For the laptop:
For the display cable:
For the monitor:
For the hub/dock:
① Use the Thunderbolt 4 cable that came with the dock to connect the dock's Thunderbolt 4 upstream port (with a computer icon) to your laptop.
② Plug one end of the included power adapter into the DC-IN port and the other into a power outlet.
③ Press down the power button, and the LED will turn green and then blue. If the light does not turn on, the dock may be defective.
