MacBook Air external displays are mirroring
 

Hi, I am using a MacBook Air (2019, Catalina) with a StarTech dock, DisplayLink 5.2.1, and two BenQ GL2460 monitors. However, the two external monitors act as a mirror of each other instead of two separate displays. I've followed the steps listed here https://support.displaylink.com/know...k-display-on-m , but it has not solved my issues. Any guidance on how to proceed would be great!

Thank you!

Hello,

First I would like to make sure, did you install the driver linked in the instruction or the latest one available on out website?

Thank you,
Katarzyna

Hi,

Thank you for replying. I installed the latest version of the driver.

Hello,

Please verify in System Preferences, click Displays. Click the Arrangement tab.
Make sure that the Mirror Displays checkbox isn’t selected.

Thank you,
Katarzyna

Hi, I tried that and it is not checked. I think if might be a problem with the dock I am using as the triple screen works on a different one in the office.

Hello,

Could you please collect logfiles that will show a bit more of what is going on in the background?

Thank you,

I am having the same issue. I checked all the settings and restarted multiple times. I also uninstalled and reinstalled with restarts after each action. It kept mirroring the displays. The mouse could move over to the second display, but I could not interact with anything. Only on the primary display could I select anything. It was an odd mixed state. FWIW, I do also have my laptop open, so I am using 3 screens in total. I am on macOS 10.15.4. After wasting almost an hour trying to get it to work, I ended up going back to 5.2.1.

Experincing the Same issue on MBP 2019
 

I currently have three screens and the laptop. Mac OSX shows all of the displays, however the two that are connected to the displaylink system are mirroring. This is with the latest version of the mac drivers, previous version was working properly.

Catalina 10.15.4

I am also having the same issues. I just sent the logfiles as instructed in earlier post in this thread. I installed it this morning.

DisplayLink USB Graphics Software for macOS
Catalina 10.15, Mojave 10.14
Release: 5.2.4 26 May 2020

I paid attention and it is now working!
 

Thank you to Jakub for putting a post out early this morning. It is at the top of the Mac Software section. Putting it here as well. Once I installed the new "DisplayLink Manager App 0.5 Beta", it figured things out on its own.

Plans to distribute Displaylink App on App Store or brew?
 

Hi Folks,

Thank you for sharing the fix by using the Displaylink App.

I am curious if there are any plans to distribute the Displaylink App on the Mac App Store or via brew?

Also, if I want to use the Displaylink App, do I also need to install the driver or does the App take care of the driver? I'm hoping to not have to install both.

Thanks again :)

got the same problem with two monitors attached with HDMI to An USB C HDTV adapter with multiscreen display, my MacBook see both displays as one and they mirroring. and that is not what I want

maybe try using the displaylink app as described in this post?: https://www.displaylink.org/forum/sh...90028#poststop

good luck

Yes, there is a plan to add the application to Mac App Store we do not have any dates set yet but we are aiming to get it added there.

All you need is the application, there is no need to install the classic driver.

If this issue happened after upgrading to driver 5.2.4 please try out the Beta driver.

Thank you,
Katarzyna

Thanks! :)
 

Thank you Katarzyna :)

Is there a Beta driver to fix the mirroring problem in MacOS 10.14.6 Mojave?
I downloaded the 0.5 Beta but its only for Catalina. Thanks

Downgrading to v5.2.1 solves the problem
 

I had the same problem with my MacBook Pro (Retina, 15-inch, Mid 2014) which is running on macOS Mojave V 10.14.6 (18G5033) and DisplayLink drivers v5.2.4.

I downgraded to v5.2.1 and everything works fine right now.

Release Notes of v5.2.4 states that;

Clearly bug 30765 is not resolved correctly, still has this problem (maybe at least on Mojave)
