Some external monitors have native drivers that power some components or features of the device. Follow the below steps carefully to reboot and reconnect the devices: Turn on your HDMI device (Speaker, TV, etc.) and then turn on your PC/laptop. Switch the cable to a different DisplayPort if the adapter has more than one port. If using a DisplayPort adapter on your computer, ensure the cable is correctly plugged into the adapter and the adapter into your computer. Use a can of compressed air to remove foreign materials from the DisplayPort on the monitor and your computer.

Since the display signal on the docking station is DP, it suffers from the same issue with the Mini DP port as is described above.Ībout reproducing: You may be able to reproduce the problem on your machine either with a cable connected to the Mini DP port or with a Thinkpad docking station since its display signal is wired through Displayport. This is somewhat unfortunate since otherwise the Thinkpad docking station works even without any USB injector kext. Known issue that is listed in README.md related to this problem? On my machine (T460s with FHD, macOS Big Sur 11.0.1 (20B29)) the HDMI hotplug works fine (using your 0.6.3 configuration) however the Mini DP doesn't - plugging it in causes the internal display to go black and the internal screen will not turn on even if the external (Mini DP) monitor is disconnected.
