M1 Mac Intermittent Problems with Plugable Displaylink Doc

zoltansz · 03-19-2022, 07:57 AM

Hi, I have an old Plugable UD-3900 that I am using with My Mac mini M1 via USB-A.

When it is working, it uses quite high CPU, but otherways it is perfect. It is working after boot automatically.

However, typically after the mini goes to sleep the DisplayLink Manager ceases to work, just a black screen.

I can open the DisplayLink Manager UI, but it freezes when I want to quit.

I want to save my USB connector so what I am doing is to Force quit DisplayLink Manager and restart t manually. It is working 100%, but I hate it. I have to do it 3-4 times a day.

Another bug is that many times a day the default monitor swaps by itself so my DisplayLink monitor becomes the default while I am editing my code.

Also, Flux is working on my "normal" monitor only. DisplayLink doesn't support it. Yet. Only on Macos. (On Windows it is fine.)

Please do something about this bug.

Thanks,
Zoltan
