Displaylink ceases to work in 10.13.4

[Pbowater]

OK, so not entirely smooth, but am back up and running.

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.

What do you consider the proper cleaning routine? Brand-new MacBook Air (2017, 13") with Mojave freshly installed. Downloaded and installed v5.0, then rebooted: black screen. Ran the uninstaller and rebooted: black screen (as expected). Re-ran the installer and rebooted: black screen. Repeat with various combinations of dock attached and unattached, monitor attached and unattached, etc. Add in some zapping of PRAM and resetting of SMC and you've got a picture of most of my evening last night. If there's a "proper cleaning routine" I'm missing, please point me in the right direction. Well beyond frustrated here.

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.

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

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.

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

Did you give permission to installed drivers in privacy and security?

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.
