Had a similarly frustrating experience trying to connect a new gaming PC to a LG Ultrafine 4K. The all-USB C aspect of the monitor was fine when I only used it with my Macbook, but made it terribly painful to use with anything else. In the end I found a HDMI to USB C dongle which worked, also included a plain USB 2.0 cable for audio. Apparently I was ‘lucky’ to have the 4K rather than 5K, because, from my research at the time, nobody knew of any dongles or cables that would support the latter at full resolution (I think this is the same issue as in your article)
