Default Dell D6000 issues with 2 screens MacBook M1

Hi

Ive been using a Dell D6000 with 2 LG screens for ages with no issues

Recently started using my MacBook Pro M1 2020 (Ventura 13.2.1) with these screens (LG27UL850W) via the D6000 dock and the experience has been patchy to say the least

Main issues are:

Only one screen recognised

When 2 screens are recognised, 1 will be perfect with no issues and 1 will be grainy/blurry

Need to disable DisplayLink Manager multiple times and unplug USB C cable from Mac on multiple occasions to get anything to work

Nearly impossible to wake the computer up when in clamshell mode

Takes about 10 minutes each day to get the bloody thing to work!

Thought it was firmware on the D6000 so upgrade that (on my old laptop as cant be done on mac) but that doesnt help

Getting close to flogging the mac at this stage now and getting Mac Mini M2 that natively supports 2 displays

Any ideas how to resolve this?

Thanks a lot !
Jim

Hello,

The logfiles show that the two available monitors are running in 1920x1080 resolution, is this correct?
Is this the resolution you would like to use?

As for the logfiles I will need them to be gathered when the monitors are not working - so before you recover from the issue as now I see that everything is working. Also there is a lot of other events in the logfiles that are not related and I would like to narrow down the number of information in the log so please clear/reset those.

Do that while the issue is happening - run the DisplayLink Support Tool and in the upper left top corner of the menu bar you will see Advanced. Expand it and select Clear logs and reset verbosity. After the process finishes if the issue is still ongoing please run the tool to gather the logfiles again. if not, then reproduce the issue.

Thank you

OK and did support reach a positive conclusion to jimrudd problem?

I have a very similar setup as him but I'm postponing my upgrade of macOS just because of this issue reported in this thread.

My current setup:

Device: MacBook Pro M1 2020
OS: macOS 12.6.3
DisplayLink manager version: 1.6.1
DisplayLink Device:
Dell D6000S
2 X LG UltraFine Ergo 27UN880-B connected by DisplayPort
