I have M2 MacBook Pro with two 4K Dell 27" external monitors. I connect them via TBT3-UDZ dock. The problem when I connect them to MacBook, the displays won’t show anything. But if I unplug dock power cable and plug again, then I see the display. This happens every time. Any solution for this. All the cables are connected to GE surge protector.
Hello there,
Thank you for reaching out on the forum!
I am sorry to hear that you are running into issues with your TBT3-UDZ, but I would be happy to help diagnose the issue here.
First, can you confirm that you are trying to connect to your laptop using the included Thunderbolt 3 cable that came with your dock? We’ve seen issues arise when a third party cable is used.
Next, some steps we’ll want to take are to perform a power-cycle of the unit to reset its internal hub chipset. I know that you mention that you unplug and re-plug the power cable to the dock, but this is a slightly more methodical approach we like to try. We’ve seen that this can often restore the dock back to a working state when one or more of its functions are not quite working. To do this, please follow these steps:
- Disconnect all USB peripherals and displays connected to the dock
- Disconnect the docking station from host machine, then disconnect the power adapter from power
- Leave unplugged for 1 minute for power to dissipate
- Connect docking station initially into power only
- Connect docking station to host machine, then connect USB peripherals and displays, then test for functionality
Please let me know if this helps at all.
Thank you,
Evan
