Do you see any corruption on the internal screen or the screen you have connected to the built-in external port on your MBP?

Many thanks,

Sooooo this morning, I felt a little feisty, so I tried a thing.

┌─[twisted@clarity] - [~] - [Mon Feb 26, 11:25]
└─[$] <> launchctl unload /Library/LaunchAgents/com.displaylink.useragent.plist
┌─[twisted@clarity] - [~] - [Mon Feb 26, 11:26]
└─[$] <>

As soon as I unloaded the useragent, the monitor sprang to life and began functioning. It's laggy, but it's working.

Attached is the output from the information tool you requested as well.

I just installed the DisplayLink v4.3 driver (mirror only) and it's at least working for me. Any news on how the "extended display" driver update is coming? and when it might be released?

Thank you,

Here is what I have done to get something working for myself again. I run 2 40" 4K monitors off my 2015 Macbook.

The first display is off the HDMI port from the AV adapter. The second display I was able to get back up and running by moving to the 4.3 Beta driver that only supports mirror mode. I then opened up the clamshell (which I usually keep closed) and load up SwitchResX. Now I can mirror the clamshell display which I can now set to run at 4K. So I have 3 displays (sorta) running on my macbook 2015 while I ignore the TEENY tiny fonts on the clamshell display itself.

Its not perfect, but why i hadnt thought about it before. Least I have 2 monitors again
Apple TV + HDMI = 2 monitors!

Such a pain. I switched to the Dell WD-15 dock as that doesn't use DisplayLink. It gets me one external monitor, but not two, even though it has the capability to run two monitors in Windows. It seems that Apple limits it to a single external display on a thunderbolt port for some reason. The only solution I've been able to come up with is buying two Thunderbolt (USB-C) to Display Port adapters and I will have to plug in 3 cables when I dock.

Yes Apple, unlike Microsoft, does not support MST through TB. Its an OSX limitation. This means you get mirrored monitors on TB but not extended.

According to this product, macOS does only support dual monitors on a single cable via TB3. I'm not sure if it's MST. But see for yourself: https://www.i-tec-europe.eu/index.php?t=3&v=480

I get cloned screens when I connect an MST adapter via USB-C (USB 3.0 Gen 1) on my MacBook ( not Pro). The pro models have Thunderbolt 3 ports so it should work as pictured on that site.

However, using a MacBook 12-inch – which only has one USB-C port – a DisplayLink docking station was the only solution to connect two external monitors via a single cable. It was the perfect single cable solution until Apple broke it.

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

[torimorris1]

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!

Read about the Airplay workaround but this fails too. I have DisplayLinkUserAgent approved as an app to control my computer in the Security and Privacy settings. I have a freshly installed macbook pro (2014) with no previous display link drivers. I installed new driver, allowed the Display Link software in privacy settings, set the DisplayLinkUserAgent to be allowed - and nothing shows up in airplay. Mirroring option is checked in Display Settings.

Now what?
