Big thanks to the DisplayLink team for not giving up. I hope DisplayLink docks will be back to normal soon. Although you compress video data for USB and decompress on chip, have you explored this "hack" yet?

https://forums.macrumors.com/threads...-work.1974167/

What if you trick the macOS into "display port alt-mode" and transmit video data via the extra lanes? The DisplayLink SoC may needs a reprogramming for accepting data via Display Port than USB directly. The hack in the link above perhaps also requires macOS to allow support for MST – if you want to run two extended monitors, which it never did on Intel GPUs.

The downside is that USB 3 ports will drop to USB 2.0 due to lack of bandwidth.

I'm trying to give you ideas, although I might be wrong.


There are no alternatives. DisplayLink's business model (unique selling point) is solely based on their proprietary compression technology, allowing them to squeeze a broad bandwidth video signal through a tight USB cable.

It seems Apple has fundamentally changed how frame buffers are passed on to external displays. As far as I understand the DisplayLink driver was sort of a Man-in-the-Middle hack – hijacking the frame buffers and compressing them for the USB's bandwidth bottleneck. Apparently, that trick doesn't work anymore. Now, if that's the case it does take more effort than just a few new lines of code.

We just have to be patient, stick with 10.13.3 for now, and hope everything will be fine again soon.

Has this issue been resolved for you? I am experiencing the same problem and am wondering if you've found a solution.

Display does not work
 

I am operating High Sierra 10.13 and my display is stuck in sleep mode. Have uninstalled and reinstalled the driver several times to no avail.

Please help me find a solution!

Since this is a new solution, how about some quick documentation of how to choose and set which monitor is cloned? I'm not seeing a place to make that choice right now.

MCT makes similar but inferior products. I have one (within a J5Create USB dock) but I do not recommend them. Since upgrading to High Sierra their driver has consumed high amounts of CPU and neither J5Create nor MCT seem willing to give the matter serious attention. Even when it was working prior to High Sierra it was a rather poor solution.

I have numerous DisplayLink adapters (USB2 and USB3) and they're all working very well on this 2012 11" Air (running 10.13.3) and I'm confident that DisplayLink will have this resolved as quickly as possible.

10.3.5 Beta 1 - No change
 

Didn't think it would matter, but first beta of 10.3.5 does not change the DisplayLink problem.

I did happen to find a alternative solution, Matrox DualHead2Go Digital ME works with macOS 10.13.4 its a bit more expensive than a DisplayLink adapter but it works in 10.13.4. Basically splits the display in 2. The dock and title bar end up split between the screens but it works

Thank you! Please keep the pressure on Apple.

Is there anywhere Mac users can register their annoyance / frustration to help convince Apple to fix this bug asap?

I initially bought a pair of the apple USB-C to HDMI adapters, these were absolutely junk, each time I woke my brand new power mac it would hunt for monitors, connect them, then disconnect them, connect them again and get stuck in a loop requiring me to disconnect the monitors and add them back on, one by one.

I bought a nice plugable dock to overcome Apples useless dongles making my MacBookPro usable once more.

Apples latest update has me stuck using their crappy dongles again. There was a time when Apple prided themselves on their easy of use and quality of products (especially when using their own peripherals), these days they're bloody useless.

Since not everybody has an Apple's Developer ID, the only other way I could think of is via www.change.org

Alternatively, you can also vandalize in an Apple Store to express your frustration. :D

Does anyone know if you can clone the native display while its closed in Clamshell mode? I use mine thusly, so installing beta 2 would allow me to use 2 monitors (one displayport and the 'cloned native display') effectively. however if since the native display is off, and it wont work, doesnt help me much.

It seems that Apple retail employees are aware of this issue. I needed to drop some hardware off for repair at my local Apple store. One of the hardware repairers, who also does time on the Genius Bar, acknowledge the DisplayLink issue and confirmed that the hardware can come back with 10.13.3 installed (as per my request).

Just want to share my temporary workaround to continue normal life with 10.13.4 with 3 monitors connected to MacBookPro 2015.

I used one DisplayLink adapter, so 3 monitors were connected over: DisplayPort, HDMI, DisplayLink. All had worked fine with clam-shell closed. After upgrade to 10.13.4 I installed the latest DisplayLink driver 4.3 beta 2, opened the laptop screen and set it to be cloned to the monitor connected over DisplayLink. DisplayLink driver clones the "main" monitor, i.e. the monitor that has menu bar in "Displays / Arrangement" system preferences. If your built-in display in not the "main" one, just drag menu bar to it in display arrangement settings.

To fix wrong resolution of the cloned screen I used DisableMonitor v1.92 utility, https://github.com/Eun/DisableMonitor. It allows to set any resolution to any connected monitor. My monitor wired over DisplayLink was just 1920x1080, so I enforced the resolution using the utility instead of original retina resolution of the built-in display.

So after trying and trying and trying, and 2 sleepless nights I managed to revert my Mac to MacOS Sierra 10.12.6 and finally managed to get my 2 external displays to work.

MacBook Air (13-inch, Early 2015)
1.6 GHz Intel Core i5
4 GB 1600 Mhz DDR3 RAM
Intel HD Graphics 6000 1536 MB

This is as far as close I could get to MacOS High Sierra 10.13.3

For any poor soul like myself (just before now) who is still trying to get their Macs working with display link adapters and trying to downgrade, this might be helpful.

Steps:
1. Install the OS that came pre-installed with your Macbook (pro, Air etc. etc.). If you are at 10.12.4 or higher (which I am guessing you are, otherwise you won't be looking at this post), there is a nifty feature that you can use to revert your mac back to factory defaults.

PS. ALL YOUR DATA WILL BE LOST, SO MAKE SURE TO BACK IT UP BEFORE ATTEMPTING.

Restart your macbook, press and hold: SHIFT + OPTION + COMMAND + R keys (you would need both hands, I tried to use one but could not, maybe you get lucky, lol).

2. Once the rotating globe appears, you can let go of the keys and it will download just a bunch of bootable files to kick off the installation.

3. In the new window that appears, click on Disk Utility and Erase/format your main disk (format with Mac OS extended).

4. Quit the Disk Utility and click on Recover Mac OSX (in my case it is OSX Yosemite, 10.10.5 with which my Mac was shipped). Let it do the rest, once the installation is complete, you can follow the on-screen instructions and get into the OS.

5. Next part comes from App Store. From this link, https://support.apple.com/en-us/HT208202, click on "Get macOS Sierra." in the middle of page somewhere (it will be in blue highlighted text) which will opn App Store. Click on "Get".

6. From here, follow the onscreen steps once the download completes. It might take a lot of time depending on your internet connection, download is about 5.6 GB.

7. Once all is set, you can download DisplayLink drivers version 4.1 and it will work.

I have tested it with my Mac and it worked like a charm.

I downgraded from High Sierra to Sierra but at least I got my two external screens working.

Any comments/corrections are welcome.

Thanks.

Installed the new beta driver and it mirrors. Works as noted, however my screen resolution is not adjustable. I have a black bar on each side of my external monitor as there is no place for adjustments.

You need to go back read the advice.

The mode in the beta driver is not mirror mode its clone mode, therefore the resolution and the aspect ratio cant be changed. The software is doing exactly what DisplayLink say.

in 4.3 beta 2 there is no mirror and no extended desktop just clone mode.

The resolution of cloned monitor can be changed, please read my post above. The utility DisableMonitor, https://github.com/Eun/DisableMonitor does the work.

And I was able to change my resolution through SwitchResX (http://www.madrau.com/). When I plug in my DL device, it automatically changes to 4K resolution (which is unreadable on my laptop) and clones it perfectly to the connected monitor.

gave up!
 

Returning the USB-C docks and have Thunderbolt 3 docks on the way. Two monitors vs. three, but at least more than one!

It works for me.

Sorry, my comment got separated. I was referring to clamshell mode, which works for me. At least I don't have to stare at a dead monitor.

If I am not mistaken its been 12 days since any official word from DisplayLink on this matter. Its really beginning to look like these are now toast. Even over in the apple support thread the focus is on finding different solutions rather than holding out that Apple will assist to fix this. I don't think anyone thinks that Apple even wants to try to support those that created a separate industry that assisted in use of its devices in cross platform environments. Anyway, I've had to jettison my DisplayLink dock and go to an elgato due to the fact there is no known date when this will be fixed and no comms from DisplayLink on any kind of progress.

10.13.5 Beta 2 does not fix the issue.

We've been here many times before. It takes time, often weeks before a set of drivers are released that offer a fix or partial fix but considering I've been using the same DisplayLink device since 2011 I can't complain about the support.

I agree, DisplayLink is trying their best. They created 4.3 beta to clone displays pretty quickly. With adjusted screen resolution that provides workaround for me. Likely the proper solution depends on Apple side, while Apple seems to care not too much of the issue.

Yes agree they may try their best but its now 3 months since the start of this thread and in that time there has been minimal information from DisplayLink on any progress. Thats a quarter of a year. If they can not manage to get any prospect that are worth informing people about in 12 weeks then I can not hold my breath for another 12 weeks to return to having multiple dislays. I had to purchase something else. It was my choice I agree but the lack of support engagement drove me there.

You're getting a bit overemotional here, but it's totally understandable. As a private person at home you have more options to choose from, in enterprise environments you have to stick with the approved hardware a while longer, which is even more frustrating.

My guess is that without Apple support there is no easy way to fix this. Hopefully, with the final release of 10.13.5 both parties i.e. DisplayLink and Apple, will have sorted it out. I'm still on 10.13.3

There is one positive thing I noticed with the latest beta driver. It seems audio is now being directly delivered via HDMI, no need to plug in AUX jack separately. :) If only HDCP would have also worked eventually... But you still can't watch any HDCP protected movies via DisplayLink. *gasp*

Actually I think I understand how I feel and I am not getting over emotional. I was over emotional when this became an enterprise issue and the company I worked for decided that this was the straw that broke the camels back and now no longer supports Macs within the environment at all. You see there was nothing publised in release notes by Apple that upgrading would break anything and so the extra work to rollback alot of Macs resulted in getting given a windows machine instead. They waited a couple of weeks and then decided that they could not continue on without support of knowing it would be corrected and the easiest, fastest, and cheapest solution was to get rid of Macs.

So, its at home now, becoming less of a work horse into a home use only paradigm. This seems to be what apple wants.

So not over emotional at all. I now have a windows machine for work that functions with DisplayLink even after microsoft push out updates. It also has USB-C ports so my Apples accessories function with it. My only loss is needing to use windows during a working day.

so you expect apple to release notes how EVERY third party driver and plug in will function after the update?

The only thing I can criticize is the poor information management from Apple and DisplayLink! There was no warning ahead of the new update.

DisplayLink posted a warning on their download site way too late. Although, this topic existed for months already. A few people even thanked me at Macrumors forums for pointing out this severe bug. I guess, too many people updated carelessly and ended up with a useless DisplayLink device.

Most enterprise IT departments are hostile towards Macs. It has always been like that, because Macs are a niche product and expensive compared to cheap Dell/ HP laptops which you buy in bulk anyway. However, Windows is not always an option. Some software doesn't run on Windows e.g. design tools like Sketch, Flinto, and Xcode.

DisplayLink technology is being used across many major vendors. It's not some small 3rd party chop shop piece of hardware. So yes, Apple's QA failed here big.

Apple has not respect for the ecosystem that their products are part of except when those products are apples. It has resulted in the decline in Macs over the years and its going to continue to be the decline of Macs. If Microsoft can perform major upgrades without crippling everything that is integrated their OS then only reason that Apple can not is because they do not wish to.

Unfortunately Microsoft can't perform an update without crippling entire machines. Just do a Google for "Windows 10 Creators or Fall Update won't boot" and you'll see a host of unhappy users rebuilding their machines or performing PC voodoo to resurrect their computer.

However I agree it is a great pity that Apple steamrollers architectural changes without working more with 3rd parties.

displaylink.com also down?
 

I came here with the same issue. But it sounds like there is a beta version of the driver that may work? Unfortunately displaylink.com seems to be down at the moment.

Don't expect Apple put anything in there release notes about it being fixed.

Not even going to attempt to try it on my now home Mac to even find out. I don;t trust Apple and whatever else they may have packaged in here that will result in me loosing hours. I'll wait to see someone else offer up whats broken in forums.

Apple update did not work for me
 

Steps I tried:

1. Downloaded update
2. Confirmed did not work with restart (still showing cloned desktop)
3. Uninstalled DisplayLink beta driver
4. Restarted
5. Confirmed did not work (black screen)
6. Installed current latest release of display link driver
7. Restarted
8. Confirmed did not work (black screen)

Hello,

I can confirm that:

- After removing the beta drivers and reboot
- Download Apple Security update 2018-001
- Install DisplayLink 4.1 Drivers (not beta ones)
- Reboot

Thats was working for me.

Dear DisplayLink macOS users,

As we previously advised, we are aware that installing macOS version 10.13.4 will cause DisplayLink connected displays to go blank after the OS update, with the latest DisplayLink driver release 4.1 installed.

Extended displays continue to work as expected in macOS 10.13.3 - this is why we recommend remaining on macOS 10.13.3 or earlier at this time. Functionality such as Ethernet and audio, where implemented, is unaffected on macOS update.

DisplayLink has committed significant resources to finding a way to restore extended mode display support in a future release of macOS.
We have made solid progress towards identifying a solution, however our team needs to complete more work before we can communicate a release plan for a driver that will restore extended mode displays.

In the meantime, DisplayLink driver 4.3 Beta 2 enables clone mode, but not extended mode, displays in 10.13.4. Users who have already updated to 10.13.4 should install that driver.

We will update you on this thread as soon as we have further details to share.
Thank you for your continued patience and we appreciate your feedback and support.

Kind regards,
Alban

This did not work for me...
