The 10.13: High Sierra Thread

[Shanesan]

For those on the developer release, please post here your tales. As this is a maintenance release for Sierra, and with the new Metal 2 architecture and their announcing changes to the Window Server right in their presentation, and the fact that it's not a public beta, there WILL be issues with the new version and current Displaylink drivers.

To maximize the help to DisplayLink, make sure you provide the following info:
MacOS Version (the first release is 10.13 17A264C)
Computer Make and Build Year (ex. MacBook Pro Late 2012)
Displaylink Driver Version
Displaylink Device
What You Are Experiencing
What is Expected

Also expect DisplayLink to not put major effort into supporting dev builds, as the beta will change a lot, very rapidly, and patching Apple issues only to be broken in a week isn't fun for anyone.

[Shanesan]

So I guess I'll start with what I got:

MacOS 10.13 17A264C
Macbook Pro Late 2012
DisplayLink 3.1 (uninstalled and reinstalled)
Device: Plugable USB 3.0 docking station UD3900
Experiencing: A black screen on the Displaylink-run monitor, but the mouse can be seen on it. Mouse runs very smooth.
Expected: Stuff more than the mouse on the display.

[Carlo]

Yes no pixels, but the contents are rendered if you take a screenshot. This means that we don't get updates from the OS. Analysing this now.

Another issue is the window server crashing when going to mirror. The same issue is reported to happen with eGPUs so we're optimistic on this being fixed soon.

There's another minor issue, a crash of one of our processes.

Has anyone spotted anything more?

Cheers,
Carlo

[Shanesan]

Has anyone spotted anything more?

Hi Carlo,

Love the fact you guys are tackling this as hard as you did with the Sierra beta.

See OP for specs.

Sometimes when the display is connected (over HDMI if it matters), the computer begins to heavily lag, mouse jumps around at around half a frame per second on all displays, and functionality of the computer becomes zero (clicks don't register, etc). After disconnecting the displaylink device, the system stabilizes.

Once I can reproduce this, I will try to provide process information...

MacOS Version: 10.13 Beta (17A264c)
Computer Make and Build: Year Mac mini (Late 2012)
Displaylink Driver Version: 3.1
Displaylink Device: Coredy USB 2.0 Display Adapter
What You Are Experiencing: Installed drivers (fresh). Display is detected. Mouse pointer can be seen and moves on the screen, but no windows can be displayed. Just a black screen.
What is Expected: Additional screen to be visible as a desktop.

[jpmiller03]

Black screen but registers in the Displays prefpane properly, and shows the mouse cursor.

[Carlo]

Some news on the bugs we have with Apple.
They main issues have been closed as duplicates of Apple bugs. So Apple is aware and is hopefully working on solutions.
As usual, it's useful for everyone with a developer account to raise the same issues to increase the priority for Apple.

This means that on our side we're left with looking at workarounds.

Cheers
Carlo

[jpmiller03]

Do you think there'll be a beta? I'd like to be a part of it if so.

[jamesbrobinson]

Now on developer beta 2 of macOS High Sierra.

Exactly the same issue. Screen is identified, mouse pointer works on the screen however it's an entirely black background, and I can't put anything on that screen.

[Lasse S]

Just installed the first public beta (which is the same as Developer Beta 2 Update 1) and I'm experiencing the same issues as everyone else - responsive mouse cursor but black screen.

macOS: 10.13 Public Beta 1 (17A291m)
Mac: MacBook Pro (Retina, 15-inch, Mid 2014)
DisplayLink Driver: 3.1

[M. Holkamp]

Black screen but registers in the Displays prefpane properly, and shows the mouse cursor.

Macbook Pro (Late 2013)

[jpmiller03]

Still have black screen that is registering properly. Also plugging a display into the DisplayLink hub crashed the logged in session back to the login screen.

[Lasse S]

Still have black screen that is registering properly. Also plugging a display into the DisplayLink hub crashed the logged in session back to the login screen.

I just updated to Public Beta 2 and I have the same problem - if I connect a display to the DisplayLink dock something crashes and I get sent back to the login screen. Everything else in the dock works though - ethernet, USB, etc.

[Carlo]

Hi,

If you are logged out when connecting the DisplayLink screen(s) then you've likely hit a macOS bug that is triggered by mirroring screens. It's probably the same issue it's currently happening with the eGPU kit.

On some systems mirror may be already set for the external screens so every time they are plugged in you'll automatically hit this issue.
A possible workaround is to delete all persistence information, so at the next plug in a default extended state can be chosen by macOS.

This is how to delete persistence information from Terminal. Please note that the following commands if entered incorrectly may delete any file on your system:

To clean user preferences:

rm -f ~/Library/Preferences/ByHost/com.apple.windowserver.*.plist

To clean global persistence:

sudo rm -f /Library/Preferences/com.apple.windowserver.plist

After a reboot the display settings will reset to default, which should be extending to the right and not mirroring.

Best regards,
Carlo

[Shanesan]

sudo rm -f /Library/Preferences/com.apple.windowserver.plist

Morning Carlo! I followed this instruction to see what happens. The following result occours:

Running on 17A306f
Run command, disconnect DisplayLink device, restart the computer.
Computer boots normally with just the laptop and Apple Monitor plugged in over Thunderbolt.
Plug in DisplayLink with HDMI monitor attached.
WindowServer crashes, brings me back to login screen. Login screen is sky blue with a mild gradient, the background is not the standard background.
When trying to log in the WindowServer crashes and sends back to login. Repeat until you disconnect the HDMI and login screen returns to normal and login process is successful.

Hi All

For those wanting to try a new driver for High Sierra, it is now available in the Alpha forum here:

http://displaylink.org/forum/showthread.php?t=65395

Wim

[M. Holkamp]

I have installed the Alpha driver and so far so good.
The second screen gives me the right picture and the mouse is moving.
Monday at the office i will test the DisplayLink with 2 monitors.
Keep you posted.

[Lasse S]

I've installed the 4.0 Alpha as well and have been running it a couple of hours now. So far everything seems to be working great - dragging application windows to the DisplayLink screen and moving them around is very smooth. Maybe not quite on par with my Thunderbolt 2 connected displays but very close ;)

One thing I noticed was that the macOS menubar renders correctly now - no more faulty transparency and greyed out menu items are also readable now. I assume it has to do with the Metal optimizations.

All in all I'm very satisfied - great work guys! 👍🏻 :)

[scotty_insa]

With the DisplayLink plugged in USB w/1 monitor attached and a 2nd monitor attached HDMI via thunderbolt, the built in screen remains completely blank and requires holding down the power button and rebooting to get the built-in display working. This happens when in clamshell mode and the DisplayLink device, power, and thunderbolt are disconnected, then shortly after the built-in screen is opened. This only happens when DisplayLink is plugged in. If there is only a thunderbolt monitor and it is in clamshell mode, it wakes correctly.

Hi. I hope it's OK to join this thread.

I re-installed two Mac's (MacBook Pro, 2012) with macOS High Sierra and installed the newest DisplayLink software. I am using an HP 3005pr Port Replicator with two screens.

Everything was working well under Sierra, but my screens are not working under High Sierra. They are even not detected in System Preferences. The other functions, USB and Ethernet, worked plug and play as they should

Hope you can help me.

My Display Link display worked fine under Sierra. Upgraded to High Sierra, uninstalled the old version, installed the new version. No picture at all as the device is not visible in the USB section of the System Report. Tried connecting it to a powered USB hub, still not recognized.

Any next steps or am I stuck waiting for a driver update?

Hi,

If your device is not visible as a USB device then we need to analyse the HW and host controller configuration, it's not a driver matter as the driver has nothing to connect to.

We need to reproduce this as soon as possible. The best thing would be for you to send us the information gathered by our tool: http://support.displaylink.com/knowledgebase/articles/755301

We'd still need to know which kind of device (model and manufacturer) you are trying to connect and any information about how the device is connected (adapters or hubs).

Thank you

That did the trick! I didn't get the popup as part of installation, but uninstalling and reinstalling got me to where I could click the "Allow" button and enable the extension.

I have the latest-get mac mini, exporting to several screens at our church, and the USB 2.0 adapter outputting to a screen. I recently updated to 10.13 and updated to the latest software for the adapter.

Upon startup, all screens are dark, with no response. Once I unplug the adapter, I'm able to log in again and access everything, but plugging it back in immediately hijacks the system.

Any ideas?

I have been in contact with Tripp Lite support who say that the driver is currently only supported through 10.11. No word on when it might be addressed.

[Russ]

I've just installed the 4.0 driver and did not need to perform any unblocking - no prompts, no message to allow or anything.

I've found that if i have 1 external display connected, everything works fine. The moment I attach a second external display, the system tries to go into Mirrored mode and given that it is not currently working, everything fails. Is there a workaround for this?

For the bug itself, it would be very helpful if you could raise a defect with Apple.

I am running 2 x VGA displays via USB-C-to-VGA and HDMI-to-VGA adaptors from a late 2012 Mac Mini on High Sierra. I am trying to run a 3rd VGA display via a DisplayLink USB 3-to-VGA adaptor. The driver was initially blocked by security but I clicked allow. It is recognised in the System Hardware list - screen grab attached. Also attached, a Verbose report using your Support Tool.

The screens are being shared with other computers via an Adder KVM switch but I've tried adding the 3rd monitor/DisplayLink adaptor directly to a stand alone VGA monitor with the same result. All screens are fairly ancient 17in Dell IXODs

Connecting the adapter alone causes no change. Attaching the display to the adaptor causes the other two screens to go dark and the system to be completely unresponsive, after which a forced shutdown is needed. Hence, the report was created with only the adaptor attached.

[Volltage]

Same problem here.

[rmc2000]

I am experiencing a similar problem; you are not alone. For 2 years I have run 2 DisplayLink adaptors each driving a display without major issues while connected to a 27" iMac 5k. The machine is also connected to two external displays driven directly by the iMac. After updating to 10.13, evening running the latest driver, the machine is experiencing similar issues.

If I connect either of the two adaptors I regularly use, the iMac's built-in display and the additional two displays being driven by DisplayPort from the built-in ThunderBolt ports immediately blank. As soon as zero adaptors are connected, the built-in display and Display Port driven displays come back to life, but are at the login screen. If I log in and plug either device back into any USB port, immediate blank screens and back to the login screen once disconnecting the device.

Hi,

In case of log out when connecting displays, your system may be mirroring. This is not yet supported in High Sierra.
In some cases (for example VGA screens or projectors) this is the default behaviour so there is no workaround yet.

However in many cases it's possible to remove a saved layout by following the instructions in http://support.displaylink.com/knowledgebase/articles/1812676

Let me know if this works for you.

Regards,
Carlo

[rmc2000]

Hi Carlo and thank you for the script.

On rebooting, the two displays connected via USB did display an image for about 2 seconds. Then all displays went black. On disconnecting all USB displays, I was again presented with the login screen. Since the display preferences had been reset, all three displays driven directly by the iMac were now mirrored. On turning mirroring off and plugging the USB displays in, again all displays immediately blanked and will not return until the USB displays are disconnected.

An interesting artifact or side effect since running the script: the time and date in the menu bar are corrupt. They were not prior to running the script. I am not sure one has anything to do with the other, but felt it was worth mention in case there is a connection. To better explain this corruption, I've attached an image.

Displaylink Driver Version: 4.0.0

The graphics cards on the displaylink displays will not switch to the radeon 560 card from the intel card no matter the energy saving settings for auto switching. The built in display will switch to the radeon card but the displaylinks will stay on the intel card and the computer will try to use both cards.

This creates issues when I try to open a program that needs to use the radeon card like adobe premiere. It causes these high graphics demand programs to crash or freeze.

I have tried reinstalling a few times. It worked great on sierra and would switch appropriately. I tested this on another identical computer running sierra and the graphics card would switch for all displays when it switched.

Any thoughts? I did not get any message to enable anything in the security dialog preferences.

This is an interesting issue. Point is, with High Sierra Apple has introduced support for eGPUs. This means that applications will have to handle multiple concurrent GPUs very soon.
I'd expect professional grade apps to do that sometime next year: even Adobe has now quicker release cycles.

Apple has actually stated that full eGPU support should arrive this coming Spring. In DisplayLink we're looking forwards to this as there are some quirks at the moment while mixing GPUs (or not mixing them as in the case of the mirror issue).
For this reason GPU switching is not a feature of our drivers at the moment. We'll continue looking at it as the operating system evolves and the early multiple GPU issues are hopefully resolved.

Kind regards,
Carlo

[JimLondon1]

Hi Carlos,

Yes, I'm using the CSV-2604 via a DVI-to-VGA adapter and a standard VGA cable to an old Dell XIOD monitor at 1280x1024 (two of which are happily being driven by the HDMI and USB-C outputs already). I followed you instructions re uninstalling and reinstalling and also for running the script but all to no avail. Connecting only the DVI-to-VGA adaptor is sufficient to plunge all screens into darkness. As other have said, disconnecting the 2604 brings the screens back but to the log in screen.

While we await an Apple fix are there any other products you offer that would allow me to get a 3rd/4th screen from my Mac Mini?

Best,
Jim

I couldn't get it to work by making the external the main display. Same issue, adobe premiere will try to open and then crash. Unplug the displaylink and it works great. Plug in a different identical mac only sierra and works great.

Is there a way you can tie the displalink to the radeon card (or the higher graphics card) so that when it is plugged in it will only use that card instead of the intel integrated card? I am assuming most people that plug into a displaylink do not care about power consumption at that point as they are plugged into power too.

Do you have a timeline of when this will be sorted out? If it isn't soon I think I am going to revert back to sierra.

[jnl]

Add me to the list of High Sierra users with the same or similar problem.Before High Sierra all was fine for a year or two with 4 screens counting the DVI-USB one. Now problems since I began running High Sierra on 21.5 inch iMac. Before High Sierra and I had 4 screens working. In addition to the USB3-DVI screen, the other 3 working screens were the built-in iMac had one connected by HDMI from my Thunderbolt extender and another screen connected by Thunderbolt from the iMac itself. I was able to install newest 4.0.0 extension (85514) without security problem. When the USB-DVI adapter is plugged in all 4 screens are blank, and when I unplug the adapter, then the other 3 screens are working again.

I also have the exact same problem.

I have been running 4 external screens and my macbook pro late 2016 internal screen without issue and am using two displayport screens and two displaylink adapters. Everything is connected through a belkin thunderbolt 3 dock.

Now I updated to high sierra 10.13.1, and when I plug in all the display link adapters all screens go black.

However. If I plug in my two 4k 60p displayport screens and no displaylink screens, then it works as it should. Also if I only plug in the displaylink screens, but not the displayport screens it also works as it should. It seems to be the combination of two external displayport screens together with two displaylink screens. No matter if its though the belkin dock or usb c adapters.

Edit: Extra info
If I run two displayport monitors and connect 1 displaylink monitor all screens also go black.

If I run two display link monitors and 1 displayport monitor I get this situation where one displaylink is kind of ok, the other not ok, displayport screen and the internal screen black.
Mouse can be moved.

Hi,

If you are logged out when connecting the DisplayLink screen(s) then you've likely hit a macOS bug that is triggered by mirroring screens. It's probably the same issue it's currently happening with the eGPU kit.

On some systems mirror may be already set for the external screens so every time they are plugged in you'll automatically hit this issue.
A possible workaround is to delete all persistence information, so at the next plug in a default extended state can be chosen by macOS.

This is how to delete persistence information from Terminal. Please note that the following commands if entered incorrectly may delete any file on your system:

To clean user preferences:

rm -f ~/Library/Preferences/ByHost/com.apple.windowserver.*.plist

To clean global persistence:

sudo rm -f /Library/Preferences/com.apple.windowserver.plist

After a reboot the display settings will reset to default, which should be extending to the right and not mirroring.

Best regards,
Carlo
Carlo,

Many Thanks for the hints about mirroring! This was the last piece of the puzzle in order to get my DisplayLink adapter working once again after I upgraded to High-Sierra.

Hi,

I just bought a Ugreen USB 2.0 to VGA adapter for my iMac 27 2010 running on High Sierra.

I have installed DisplayLink Installer 85514.dmg drivers but the display is broken into the finder, please have a look at this screenshot :

Hi,

Unfortunately this issue is expected on any systems not supporting Metal. This is due to a limitation in macOS.
Metal-compatible systems use the new Window Server that avoids this issue.

Hi Carlo,

Thanks for your reply, so this is a software bug that I will encounter with all adapter using the displaylink chipset ?

Hi Carlo,

So for those of us with Mac's without Metal or Metal 2 support our USB DisplayLink Adapters will see some display artifacts, correct?

Do any impair the functionality of the display/cause panics or are they for the most part cosmetic in nature?

Hi! Any news on why screens go black when using display port screens together with displaylink screens?

Its super frustrating to be back on only two external screens after the upgrade to High Sierra.

[Johan]

Turns out my black screen issues were the cause of mirroring as well. I did not think it was the issue since this setup was without mirroring before upgrading to high sierra, but it seems my display settings where reset during the upgrade and for some reason, osx defaults to mirroring.

Trouble was that my mouse cursor got locked when I logged in (after getting kicked out), so I couldent deactivate the mirroring even with system settings open. Tab just took me to the search input field.

I solved it by finding the shortcut for toggling mirroring, which was cmd+"screen brightness down". For newer macbook pros, expand control strip and its to the far left.

After that all screens came alive. Puh!

Anyone having issues with Apple Watch not unlocking the system anymore?

When I have the device plugged in and drivers installed, Apple Watch can't unlock the Mac anymore.

Removing the device and installing drivers - Apple Watch unlocks fine....

Hi,

We haven't tried this directly, but what we know is that as soon as a virtual screen is connected to the graphics subsystem, macOS disables content protection from ALL screens.
This may include information potentially accessible through the Apple Watch security, it would make sense.

We have contacted Apple and this is apparently as designed. This in our opinion unnecessary: the internal screens support content protection and should be kept running as usual. We are also disappointed of course since we do support HDCP in our products and there is no way for us in macOS to offer content protection capabilities...

Anyhow, I'd suggest to open a bug with Apple about this issue: the more tickets, the higher the chances of changing the OS behaviour.

Regards
Carlo

[paultzirides]

Thanks for the explanation, that makes sense. I agree that it should still allow for watch unlock and HDCP-protected content playback on supported screens.,

So I finally got my screens working, but now Im getting logged out everytime I pull the plug on my external screens, when going to meetings with my computer etc. And sometimes when I get back to my desk as well. Everything I was working non gets reset, like connections to vpn, ongoing builds, vnc connections, my virtual machines get super crashed etc.

Really frustrating. Only happens when using the display link screens.

Any progress on this issue?

My issue is, that i cannot unlock my MacBook Pro with my Apple Watch when i'm connected to my CableMatters USB 3.0 to HDMI Adapter in Black or White Video Adapter.

I'm working with my MacBook Pro (Retina, 15-inch, Mid 2015) with macOS High Sierra 10.13.1, my Apple Watch Series 3, my Henge Dock and 3 DELL monitors.

1 monitor is directly connected via HDMI, 1 through mini displayport and 1 through my CableMatters USB 3.0 to HDMI Adapter in Black or White Video Adapter (SKU 103046 with latest DisplayLink USB Graphics Software for OS X and macOS 4.0.0 drivers).

My system works great but i can't unlock my MacBook with my Apple Watch if it's docked to all monitors.
When i disconnect the CableMatters Video Adapter, everything works fine and i can unlock my MacBook with my Apple Watch.
Without the monitors and undocked, the unlocking works perfect.

I think the problem is the CableMatters Video Adapter. But it works fine with macOS Sierra! After i upgraded to macOS Hight Sierra, the problem appeared.

Some other people have got the same issue: https://discussions.apple.com/thread/7679903

[paultzirides]

I think the issue is related to the way Apple is handling secure/protected content when a DL display is connected. It appears that they prevent any secure content from passing to the workstation (HDCP-enabled content, Apple Watch unlock, Apple Pay authorizations, etc.). I seem to recall reading somewhere that this is something that Apple is aware of and is going to be making adjustments to, I just don't know the timeline.

I'm in the same boat. It's frustrating to have to type my (very long) password every time I need to unlock while docked, but I'm adopting a patient approach, since things have been slowly getting better, I'm going to remain hopeful.

Late to the game here as my org asked us to hold on High Sierra until they could sort out some of the related bugs. Updated to High Sierra 10.13.1 while at the home office last week knowing some have had HS installs go awry.

Upon returning to home office and plugging in the USB it was a no go for my two external monitors - both blank but could mouse into them and it even appeared that I could move move app screens to the monitors but not seeing anything on either. Tested each monitor individually without the adapter in the mix to see if there was problem between HS and the monitors - both monitors worked no problem.

Downloaded the newest version of DisplayLink, loaded it up and still the same problem. Uninstalled DisplayLink, then reloaded the driver and boom I got two externals that I could now see backgrounds for (read not dark). I have been able to extend the displays but have not been able to extend and mirror my MacBook Air to what I use as the primary monitor - upon attempting it flashes, asks me to log into the MBA again but upon logging in all things are the same. Workaround for me is to make one of the external monitors the owner of the menu bar for ease of viewing and use. At this point all is well just which the extend and mirror would work - change is hard :).

Any insights as we progress forward are much appreciated.

Try turning off mirroring, extending the desktop to all displays, and making sure "Displays have separate spaces" is enabled (under "Mission Control" settings in System Preferences).

I finally upgraded to High Sierra a few days ago and the Dynadock stopped working. No worries I downloaded the drivers and installed them and back up and working perfectly no issues.

Fast forward to today and suddenly my 2 external HP displays were both solid green. I then restarted my Macbook Air 2013 and now the screens won't even light up. Sound etc is still running through the dock.

I have tired unplugging it all and restarting several times. I have uninstalled the software and reinstalled it twice, still the screens don't even power up, they simply are in the dormant "nothing connected" mode.

I have run the Displaylink diagnostic tool and have the results available.

Help!!! :)

You must be using the 10.13.4 beta right now. There is no solution yet. We have another thread for this here: https://displaylink.org/forum/showthread.php?t=65890

Any update on this? I am tired of staring at 2 monitors that i cannot use. I am searching for my box to ship my dock back and avoid anything to do with display link software in the future.

Me too with the display being detected, black, and only seeing the mouse pointer.

MacOS Version 10.13.3

I use 4 displays. Internal Retina, 1 HDMI, 1 TB, and the displaylink. All worked fine under Sierra (except for some artifacts in Outlook 2016 on the DL display).
I have a colleague with a very similar setup (same HW, same OS build, also startech). His works perfectly. This may help diagnose

I've tried:

resetting display preferences
uninstall and reinstall of driver
manual sniff about and uninstall of remnants (didn't find any)
separate spaces for each screen
disabling mirroring etc

Just received the Asus monitor today.

I have followed the instructions to a "T". The first time I tried to install, I got the prompt to go to Security & Privacy to allow the extension. I didn't even press the "Allow" button when the driver finished, and reported that the Installation was successful. I have uninstalled then reinstalled many times, and allowing at least 20 mins in between to allow the timer to reset. The proper reboots have been done at every step. I believe that the issue is that the extension wasn't properly installed (not allowed properly) but I cannot get prompted again to allow it.

I really need for this monitor to work - any help is appreciated!

Update 03/16/18: Please disregard this post. I returned the Asus monitor, and have replaced it with a plug and play which works beautifully. Your "support" (and I use the term loosely) is non-existent and will avoid any product supported by DisplayLink going forward.

What plug and play are you using? I'm in the same situation. Purchased a brand new ASUS that will not work.

I believe the chipset is too new and hasn't been implemented in Dec. 2017 drivers. It supports 4K and uses a more efficient compression.

The alternative would be the previous model: HP Elite USB-C G2 (X7W54AA). I'm currently using it on 10.13.3.
