AMD RX480 and Asus MB169B+ not connecting

[bulldogged]

Ah, my bad. That's clear in the docs.

I've uninstalled the AMD driver, rebooted and am now using the Gallium on llvmpipe driver.
For good measure re-installed the DisplayLink driver.

Plugged the monitor into the USB 3 port, ASUS logo appears then goes black screen, still not visible in System Settings to enable.

I've uploaded the latest support info based on using the Gallium driver.
