DisplayLink and obscure apsect ratio

Hello,

TLDR: Is 16:3 aspect ratio support by this DisplayLink?

I have a very obscure aspect ratio monitor I am trying to connect. It is a 16:3 aspect ratio running 1920x360 resolution.

I have the latest drivers for my Mac M4 mini running OSX 15.6.1.

I have confirmed that the USB displaylink dock is detected and that the displaylink manager is running. Once I plug in the monitor, the existing screen goes black locks and eventually the computer crashes.

WindowServer last exited with reason SIGNAL, code 6
then macOS watchdog panicked because WindowServer could not recover for 120 seconds.

If I plug in another 1920x1080 monitor, it works fine.
Is my aspect ratio not supported? I have a pluggable HDMI adapter and that works with some finesse, but it is ridiculously slow such that I bought this displaylink to resolve the issue but I cant even connect the monitor.

Is this something that DisplayLink just does not support?

Thanks.
