描述
Hello,
I have connected a Camera and a Microphone directly to the monitor and was hoping to use the `USB-C` port connection to extend my laptop display to the monitor since the monitor supports `USB-C`. Unfortunately, only the Microphone and Camera are detected, but the display/video is not showing on the monitor.
The display works only when I connect the monitor to the laptop using `HDMI`.

I followed the postinstallation guidelines, and I have tested both suggestions from [this](https://github.com/AdnanHodzic/displaylink-debian/issues/228#issuecomment-467889348) and also [this](https://github.com/AdnanHodzic/displaylink-debian/issues/236#issuecomment-471213411) post, and none have worked, including completly removing the `.conf` file as suggested.
I appreciate any guidance towards making this work out of the box with `USB-C`. Thank you so much 🙏
