DisplayLink and obscure apsect ratio

[DK_123]

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.

Just to set honest expectations up front, I am not a DisplayLink employee. I am a volunteer moderator.

With that said, your current macOS minor version (15.6.1) is very out of date. The latest release of macOS 15 Sequoia is 15.7.5.

As a first step, I would suggest updating your Mac to macOS 15 Sequoia version 15.7.5 in order to rule out the operating system version as a contributor to the current behavior.
