After hopelessly trying to attach an external monitor via 4 different usb-c Hubs. I happen to see some “detail” about usb-c port which says “only data-transfer capable”. Does it mean that this port won’t drive an external monitor via displaylink etc.? Afterall HDMI is “just” data transfer, I find the description somehow vague.
Btw. usb hubs I’ve tried worked with Dell XPS 15 (on Debian Buster). So should not be a driver issue as I’m running the same OS on my Librem 15v3.
