USB to HDMI on desktop: am I dreaming?

I have a desktop with a Asus Prime X670P mainboard. I bought a USB-C to HDMI on a lark, hoping that DP-alt might work since nothing in the specs seemed to say one way or another. It did not, presumably because I don't see many desktop boards that have alt mode enabled on C.

So I'm looking at alternatives, and there's a Starteck USB3 (A-type) to HDMI (USB32HDES) that they specifically say only works in Windows. Now, knowing Linux people, that sounds like a challenge but I haven't had much luck finding the vendorID/chipID for this to see if there's any success at using it in Linux.

Does anyone have one of these working, or able to suggest something else to get me an additional HDMI without having to put in another GPU? It does not need to be blazingly fast, it's just used for an extra reading monitor.
