Just purchased this from Amazon, so that I could use for dispalying two monitor).
When I connect the monitor’s HDMI to the Display 1, the monitor does not light up. When I remove the doc and use an Apple connector (HDMI to USBc) the monitor displays successfully.
I have already restarted my Macbook AIR and also, taken all the cables out then added back 1) the power cord, then 2) the usbc-6950u unit.
In our experience helping customers, most of the time, these kinds of display issues are related to the installation of the DisplayLink Manager App which is required in order to operate your USBC-6950U. The most common issues we see are the DisplayLink Manager App has not been installed, has been installed incorrectly, or is not currently actively running.
We advise stepping through the DisplayLink Manager Application installation process to see if this helps.
Below, I provide our helpful installation guide that can step you through this process.
****Please take note that the installation process does require certain permissions to be set in order for the app to install properly, so we strongly advise to follow each step carefully.**
Please let us know if this helps and if not I would be happy to discuss our next best steps.
