Seriously, use OCuLink. It costs $15 for the pcie card, $10 for a cable, and $100 for a GFX card dock, and a PSU.

OCuLink doesn't even use drivers. It's literally just a PCIE passthrough. All usual tools apply, whereas DisplayLink encrypts all data, so a big fuckyou for getting logs.

Quit giving trash companies pounds of money for abuse at scale.
