Using screen via dp alt mode

[wzrd73]

Hallo,

is there a way to use an additional screen via dp alt mode (usb-c) in Qubes 4?

I'd like to attach an Asus Zen Screen to my laptop. The screen only has a usb-c port. My laptop has usb-a und usb-c and hdmi ports.

There are usb-c to hdmi adapters, but as far as I know they don't work in the other direction.

I'm driving a monitor from my usb-c port (although the cable converts it to HDMI). I would start with looking at the output of xrandr. On my computer, I
see a listing for DP1.

If you install arandr in dom0 you'll get an easier to use interface.

Message on the screen, when I connect it: "Your device does not support DP Alt mode, please install the latest driver and try again."

The device shows up as:
