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.
Kind regards,
Alban

Needless to say, please work with Apple and try to fix this asap. Multimonitor support via Displaylink enabled dock is utmost important to me and to my colleagues.

What a great beta driver. A beta, a bad beta indeed, of a cloned blurry and blinking monitor...
This is ridiculous! Anything with DisplayLink technology or even relations from now on is in my darkest deeper and dirtier blacklist and I will do my best my world to know this. -

So Eamon, the blame belongs to the customers who put their fate and money in a company that fails to comply with the deadline of an upgrade announced 3 month in advance.
What is your job in DisplayLink ??? -

Nightmare Weekend!!!
Ok Look if you're like me who needs their screens for vital work. Then there is only 1 solution. DOWNGRADE.
Sounds simple right!!! NO it's not. Apple have removed all links to 10.13.3 or any of the 10.13.x versions and only now support 13.4 so you need to take drastic action if your screens mean anything to you.
Here's how to get around it all.
1) go here and download these old versions of 10.13.1... What are you waiting for do it now.!!!
https://drive.google.com/drive/folders/1VuY3ormZ5XORFaa8hdILus83RZ4Aqdsk2) Backup everything onto a USB-3 drive *** speed is everything here, if you don't have one pop out to the shops, it'll be faster than waiting for USB2.
3) Now you have those files downloaded, you need to un-rar tehm, download UNarchiver from apple store. once files exposed you will see an app called "Install...High Sierra.app". Remember it's location because from here things get tricky.
4) Now you have a copy of 10.13.1 (and thank god this guy has a copy) you need to put this onto a bootable USB drive (follow this guide https://support.apple.com/en-gb/HT201372). Whatever you do, you must from this point onwards disable the internet. trust me I tried this several times and the damn internet version took over the usb drive and updated automatically to 10.13.4. Saving you all the hassle here, disconnect the internet at this point.
5) If you do not have a USB drive here's a cheeky way around it. Go to Disk Utility and create a partition on your main drive for about 10GB. make sure that you do not erase anything on the disk!!!!! if it tells you that it will erase anything you need to STOP... and go buy a usb3 stick.
6) Boot up using the OPTION KEY / ALT only press this do not press CMD+R. I repeat DO NOT USE RECOVERY MODE. You're not recovering jack shit, you're about to wipe your system clean and REINSTALL 10.13.1. Maybe now you will learn about partitions and wished your system had them so you didn't have to wipe the entire disk. So while you got the chance in the next part CREATE A FEW.
7) The boot assistant will load giving you 4 options. Simply go to Disk Utility. Find your previous disk and then erase it. MAKE SURE YOU HAVE BACKED UP BEFORE YOU DO THIS. Then in Utility, create a partition for your system and normal root files, might as well do this now so if you ever have to mess with the OS you can simply wipe just the OS partition. Create 2 partitions one called "iMac HD" and the next called whatever you want to call it. This new partition is where you will keep all your files from now on.
8) once you've done with the Utility close it and then click on the Install High Sierra option.
9) DO NOT INSTALL DRIVERS YET... once you're home dry, let's make sure we never see 10.13.4 in app store again, or so we do not accidentally update that again. follow this tutorial https://9to5mac.com/2017/01/02/how-to-hide-and-show-mac-app-store-updates-video/ Also if you can disable App Store from downloading or installing anything without you saying so. Go to Preferences on App store and change these to suit you.
10) Start to isntall all your applications or if you were smart you copied them to the disk then just drag them over to your Applications folder. Now you have a choice???
11) Optional, upgrade to 10.13.3 (i didn't) go here https://support.apple.com/en_GB/downloads/10.13.1, Be very carefull and read this document as there are different updates based on you machine spect, for example there are different updates for Pro and Imacs as wells as lappys. So READ this carefully. Once your update is done.
12) install driver, but make sure the driver is the latest on displaylink's site, the one on the 6th April. Do not download the others, they will stick your machine for days/hours...until you restart and remove the device. So download the latest driver.
That's it a very long drawn out way back to normality and the quiet existence you live, with your monitors back.
What a long weekend but happy my screens are back and business is unaffected.

Yesterday I wrote:
"To make this work go to System Preferences -> Displays. You'll see 2 displays and a menubar. Disable 'Show mirroring options ...'. Then move the menu bar indicator to your primary (e.g. laptop). The display driven by DisplayLink will then mirror the laptop, giving you more than 1 external display. "I tried using my 21" external display with this setup for a while. But is so blurry that is is worse than my 13" laptop screen. I tried all possible System Preferences -> Displays -> Display -> Scaled settings. Therefore, this driver is not useful, and I've returned to using my laptop display and 1 external display driven dvi - VGA.

1. As soon as DisplayLink new there was an issue with the MacOS update and email should have gone out to all registered users. Just like when a Driver update is available. So many users could have avoided this scenario if this was simple communicated via email.
2. How probable will there be a fix?
I would like to know so I can decide if I should do a MacOS reinstall. -

The best way, and I feel the only way, to get back functionality is to restore your system to the last time machine backup before you updated MacOS to this version. If you do not have one then short of a reinstall you may be SOL...

From Mac Forums:This happens with the with the current DisplayLink driver [4.1] installed. Does Apple plan to address this and when can we expect a fix?
The answer is 'No, NEVER'. Apple again forces industry to adopt new standards without taking in consideration consumers preferences. With this move Apple push USB C as the only means to connect devices to a computer and put in the death row other standards like DP, HDMI, USB 2.0, USB 3.0, VGA, Mini Display Port, and others. Good job!!!

I just upgraded to macOS High Sierra 10.13.4 and am having the same issue. After downloading the update I now have a cloned screen between my 2 monitors. Is it possible to just download the old macOS High Sierra 10.13.3 and it will downgrade me?
