Ubuntu 22.04 No Monitors Detected
 

I am setting up with the VT 4000 on a Dell Latitude 5520 imaged with Ubuntu 22.04, have two monitors connected via HDMI. Am able to use all connected peripheral deices but unable to detect monitors. I have tried versions 5.6.1, 6.5 and 5.5 of the DisplayLink driver to no avail. Suggestions?
