I cannot detect my HDMI monitor on ubuntu 20.04 using a HDMI port provided by a usb-c adapter (Dell DA200).

There are similar questions such as Fixing Ubuntu USB-C to HDMI DELL DA200 and Dell DA200 Adapter not working on Ubuntu where the answer is to update the kernel. However, I believe am already using a far newer kernel.

Ubuntu 20.04.3, kernel: 5.11.0-43-generic

Dell XPS 15 9500
