Black screens on macOS High Sierra 10.13.4+ and Mojave 10.14 Early Previews
The driver (DisplayLink Installer 4.1.11) doesn't work anymore withe macOS High Sierra bêta 10.13.4 (17E139) and newer.
Dear DisplayLink macOS users,
We are pleased DisplayLink 5.0.1 driver for macOS enables multiple extended display support on the latest Apple macOS 10.14.2 with additional features (clamshell and clone). We continue our strong support for the Mac platform and are working on delivering future updates with further performance improvements.
Driver 5.0.1: https://www.displaylink.com/downloads/file?id=1257
If your DisplayLink enabled device does not seem to work on 10.14, this is most likely due to the OS blocking our kernel extension. Please ensure our kernel extension is enabled by the OS as described in our FAQ: https://support.displaylink.com/knowledgebase/articles/1188004
Should you still miss extended displays on latest macOS with latest DisplayLink driver, please create a support ticket so your particular case can be investigated. Here is how: https://support.displaylink.com/knowledgebase/articles/755301
Due to changes in 10.13.4-10.13.6, it is not possible to enable DisplayLink extended displays, except one using Apple AirPlay. If your Mac is from 2011 running 10.13.4-10.13.6 and can’t update to macOS 10.14, you should remain with DisplayLink macOS driver v4.3.1 to enable one extended USB display using AirPlay, with additional displays cloned. An FAQ details how to enable Apple AirPlay with DisplayLink display for extend or mirror mode: https://support.displaylink.com/knowledgebase/articles/1854724
Audio and Ethernet functionality, where supported, stays unaffected in all versions.
We thank you for your feedback on DisplayLink products that helps us further improve our product offering.

With deep regret I have to announce that ThinkPad USB-C Model 40A9 stopped working after upgrading to MacOS 10.15.3. Installing the displaylink driver v5.2.1 had no effect.

Just open a terminal and run /Library/PrivilegedHelperTools/DisplayLink/DisplayLinkUserAgent.app/Contents/MacOS/DisplayLinkUserAgent
Let the terminal on till u wanna disconnect ur external monitor

Wow 2077 comments. 107 pages. Every day I have to restart the computer after sleeping and failing to wake up properly. Black screen, nothing works. Hard restart. Fuck.
Same issue as most, running Mojave 10.14.6 and (trying) to run a MG169b+ with it. Have tried everything mentioned below and no luck I am using an Apple branded USB-C dongle, the extensions are loaded and the USB is being recognized. Why the heck can I STILL not use this monitor!??
I was forced by my company to upgrade to Catalina and ran the latest driver and would only get one screen back and the other (2) were black. I ran this fix from your knowledgease and BAM. Fixed.. https://support.displaylink.com/knowledgebase/articles/1925041-macos-catalina-10-15-black-screen-or-only-one-mon
Gram....thanks for posting the workaround. Mirroring and unmirroring took care of the problem for me.
I am not tech savy enough to know why this worked, but if you mirror the displays and then unmirror them, it brought my display back the way I had it working before as an extra desktop. Again, not saying it will work, but it worked for me after having a black screen with only the cursor showing up.
Running MacBook Pro mid 2012 16gb ram , 500gb ssd. Just updated to Catalina 10.15 and now I get the black screen of death and can only see my mouse pointer move.
I HAVE THE FIX for the MB168B and Mojave with USB C Macbooks
If you are using a macbook that requires a usb c ->usb hub (dongle) make sure you plug your power source (lightning cable) into the dongle. You have to power your usb hub (dongle) in order to get enough power to the mb168B. I hope this works
I want to be constructive, but you guys are just really terrible.
Look at all the people with this problem, find the issue and solve it...
If there is a known issue, let the community know.
Your product is terrible. Your support is terrible.
I also got 10.14.6 on a MacPro (the trash can) and can no longer get more than 2 monitors to work.
Have tried all kinds of tricks....

Having issues with my WL-UG69PD2 using MacBook Pro on OS 10.14.6. Tried 5.2 and 5.1.1 as well as 5.0.1 and all I get are black screens. Check the kern to see if it was loaded and it is. Not sure how to proceed with this since I have done everything I can possibly do.
@Des I'm having the same problems (among other) and I've been trying to get answers for a long long time now, without results. I guess you won't be getting any either…
Anyway, my issues as posted before:
1. Unlocking with AppleWatch does not work when displays are connected via dock
2. NightShift doesn't work when displays are connected via dock
3. displaylinkmanager.app has high CPU usage. (20-30% not unusual when scrolling in Safari, and I'm on a high-spec MBP 2017 i7.)
4. Built-in screen is _not_ disabled when lid is closed
It's unbelievable that DisplayLink can't even appropriately address those basic questions. I mean, if you know you messed up your implementation – tell us. Are you planning on fixing it? Tell us. You can't just stick your head in the sand forever.
Mojave 10.14.6 with latest DisplayLink driver on 2014 MacBook Air. Display is displaying correctly.
DisplayLinkManager is hogging between 70% and 150% of CPU. Macbook fan is going crazy. Just a couple of static web pages on screen, no background tasks.
Is this normal and expected?
Mojave 10.14.6 fixed via: Uninstalling, installing, allowing via Security Panel. See: https://support.displaylink.com/knowledgebase/articles/1188004
Display link not working. Have nothing but black screens for weeks. Running beta Mac OS Catalina 10.15. I see the pointer on the 2 external screens but that’s it. Found a work around (?). Go to displays and turn on mirror screen. All now work but then need the change setting of 2 screen. Then turn off mirror and all are now on. Only good until you restart or plug in monitors to MacBook.
Confirming 10.14.16 and displaylink isn't working AGAIN.. ugh.. this is killing me. I have 5 monitors and only 1 works right now. insanely counterproductive. I have 5 monitors for a reason. Someone save the day! please!

Reporting this. Running mojave 10.14.16 and latest DisplayLink update. All i see is a black screen
This issue was actually never fixed. It is now just worse than before.
I hate displaylink and my macbook nowadays.

Issue is back with 10.14.6 for me too. It either goes blank or there is vertical colour lines. Tried pretty much everything again, and again to de-install, reinstall, verify permissions. Nothing do.
