- - Displaylink ceases to work in 10.13.4 (https://www.displaylink.org/forum/showthread.php?t=65890)

As an IT support in company that has like 100 MacBook Pro devices i can confirm the following. New drivers 5.0 are working on all models except on models from 2018, where we can see only black screen with cursor on extended mode. Previous models are working like a charm. Because we suggested our employees not to update Mac OS version 10.13.4 to 10.13.6 they were using old 4.3 drivers, when they did an upgrade to Mojave now all the old drivers worked like a charm as well. So my question is how come all the models are working properly except for the ones made in 2018.. Isnt software the same? How come the hardware can make such a difference in a device that is only passing through and not doing any hardware acceleration? And when can we expect fix for devices made in 2018?

You might be, but no need to take it out on me ;)

The 5.0 cleaner was what did it for me.

Wasn't "taking it out on you" -- was simply asking what you considered proper cleaning, since nothing I tried worked. I think you misunderstood my comment/question.

I can confirm that DL 5.0 also works with upgrade to Mojave 10.14.

1. upgraded to Mojave
2. downloaded DL 5.0
3. ran uninstaller from 5.0 (and restart)
4. installed 5.0 (and restart)
5. plugged in dock, and it dual extended mode works
6. docked/undocked a few times and it continues to work.

Note: I had to do Steps 2-4 a few times.
1st time I did while docked.. this was unsuccessful.
2nd time i did while undocked, and only docked after install/restart and that worked for me.

My experience as well, now I think about it, I undocked it before trying the second time using the 5.0 cleaner.

The uninstaller that comes with 4.3 failed to uninstall itself, but by running the 5.0 uninstaller, that worked, so after multiple reboots, and a successful 5.0 installation, I have two monitors back up and running on my MacBook Air mid-2012. Prior to being able to clean things properly( but with 5.0 installed), I had the black screens, with just a mouse pointer and thought I was in a right pickle...

Performance is better, much, much better, the mouse no longer skips across the screen like it did when running 3D stuff in the browser (e.g. https://www.raf.mod.uk/aircraft/lightning/ ) . Previously it would slow down even if I de-focused the browser tab, or hid it behind another tab, now, I do still get a slow down, but nothing like before.

Checking activity monitor, when viewing the above page the DisplayLink drivers are hogging between 75 and 132% of CPU. I really don't think it should be doing that if I am honest with you.

So, at the moment, many, many steps forward (and a lot less cables) so definitely a win, but looking forward to 5.1 for sure.

For those with blank screens, try the proper cleaning routine and see what happens, nothing to lose but some time.

Thanks to the DL team.

Yay! You are my hero! I was having the black screen with just a mouse cursor on my early 2015 macbook air, and using the 5.0 uninstaller and reinstalling 5.0 fixed me! I would not have likely thought to try this if it was not for your post.

Well, no, I didn't. But I was also *trying* to inject some gentle humour in there, which also appears to have been lost ;):confused::D

:cool:

Good news, thanks krw1243! :)

Having been following this forum for 9 months now, I downloaded Mojave as soon as it was released. I then uninstalled beta 4.3. Installed beta 5. Uninstalled beta 5, Reinstalled beta 5. Undocked and repeated the cycle (probably 4 times now) and my external screen stll won't work. I'm not even getting a black screen with mouse. The screen doesn't even wake up.
MacBook Pro (13-inch, 2017, Two Thunderbolt 3 ports)
Anyone got any ideas?
Please help

Uninstall and reinstall without the DisplayLink device connected.

Under security & privacy -> accessibility, the DisplayLinkUserAgent box is ticked, yes. This was ticked from before and I did not have to re-allow.

Have tried uninstalling and re-installing without being connected to the dock (a couple of times)

Thank you for your suggestions though. Any more tips appreciated.
