Screenflow not showing displays when using DisplayLink

Hi,

I'm using a Macbook Pro 13-inc (2017) with BigSur 11.2.1 and also having 3 displays (DELL) connected through DELL DockStation WD 19.

 

The problem is that Screenflow (v9.07) is showing only 1 screen to record and not the 3 displays.

 

 

 

Am I doing something wrong?

A curious thing is that other softwares as OS Studio, Zoom, Google Meet, Skype, are able to find the other screens(displays).

 

Best,

  • Perhaps try reseting ScreenFlow's preferences. You'd need to do this in terminal though.
     

    Reset ScreenFlow Preferences:
    1) Make sure ScreenFlow is not open.
    2) Open Terminal and copy and paste this command and press Enter:To open "Terminal" (Finder > Applications > Utilities > Terminal).
    defaults delete net.telestream.screenflow9
     

    Then reboot the computer with the monitors attached and restart ScreenFlow.

      Fabio Lets see if the number of displays is a factor. Use only the MBP internal display and have only one display through the DockStation and reboot the computer.

      In other words, I want to see if ScreenFlow sees the internal MBP display AND one Dell display?

      Are all three Dell displays the same model?
      It's possible ScreenFlow can't tell them apart and is seeing only one display.
      If that's the case see if using one Dell and one different model if you can test that, will then show an additional display.

      Fabio Since your screenshot is showing "Display Disconnected" that indicates that you may not have actually deleted the preferences (which fixed a similar issue with another customer).

      Please try unzipping and running the attached file with ScreenFlow closed using the Reset ScreenFlow button (not the Gather button) which should reset preferences.

      CraigS did that, but Screenflow still the same.

      It generated a file. I've attached it.

       

      I still need to test only one display. I'll let you know as soon I do it.

      Fabio Thanks for doing the preferences reset and the diagnostics report.

      Fabio said:

       That would be important because of the possibility that multiple matching monitors might be confusing ScreenFlow's monitor detection.

      Fabio We'd also like diagnostics run with the monitors attached so we know what the computer sees. 

      Your screenshot shows that you had access to the monitors but are now disconnected. That would seem to indicate you had access to the other monitor(s) at some point. They'd like to see a video demonstrating what you are actually seeing when you try to add the monitors in ScreenFlow.

      Fabio Thanks for that. Please test without the dock and just directly connected monitors. 

      Is the dock a Thunderbolt 3 or Thunderbolt 4 dock?
      Is the dock using a driver? I believe it is but it may not be compatible with the information ScreenFlow needs.

      Also the 2017 13" MBP itself only supports two monitors.

  • Hi CraigS,

    I'm using Dell's Dock Station D6000 - https://deals.dell.com/en-us/productdetail/7mah

    It does not use Thunderbolt. This version uses USB C.

    I'm using the driver you've specified (DisplayLink).

    About the information of 2017 13" supporting only two monitors, that is correct when you plugin directly to the macbook pro itself. When you uses this Dock Station with DisplayLink you are able to use up to 4 displays.

    When you say "it may not be compatible with the information ScreenFlow needs" it means I'll not be able to use any of those monitors? Is there something planned to "adjust" this information into your software?

    Can I offer you any other information?

     The driver may not be compatible. ScreenFlow gets its monitor information from the operating system directly. 

    Fabio said:

     It may depend on what we see regarding what the driver is doing. It's a kext based driver and Apple generally is trying to move developers away from using those.

      CraigS thanks for your reply.

      Why can I access those monitors using Zoom or Google Meet? Shouldn't they work the same way ScreenFlow works?

      About the System, when I access System Preferences > Displays > Organization, I can see the 3 screens (attached). Shouldn't Screenflow recognize that as well?

     They don't work the same at all. And that may be the typical use they designed the dock and driver for. 

    ScreenFlow uses certain OS/GPU features in order to do screen recording including the ability to access all monitors simultaneously for multi-screen recording. It's quite possible the driver isn't designed to facilitate handing the information to ScreenFlow it needs to perform those functions. We need to determine that.

    That monitors seem to be showing as disconnected in the Configure Recording window is a clue. The only other time we've seen that was related to ScreenFlow preferences. Your resetting them did not fix the issue so it may indicate that it's related to the kext driver it's using.

      One more test. Can you confirm that you can use Quicktime File>New Screen Recording to record each monitor? We want to make sure Quicktime can properly record each monitor as it means more likely we can get this working.

      CraigS yes. I am able to select any of those 3 displays.

      Btw, it is the solution I'm using while I can't use Screnflow.

      Fabio Thanks for adding those details. We're looking at the possibility that an improved recorder will fix this. It's early stages, hence the test in terminal/unix to confirm what the new recorder sees.

  • Hi all,

    Has this been resolved? I have Screenflow 9 with a Targus dock going to an HP monitor and I can no longer record my screen. I have my MBPro screen closed.

    With ScreenFlow 10. Now at 10.0.5. You can always download the free trial and test.
    Generally, it's a good idea to test with the current version as most development ceases (with the exception of some OS compatibility fixes) with the older version when a new version comes out.

  • Yes it did work with v10. Any way I could get it working with v9? I've only just managed to get an upgrade to this version so not sure how easily I can upgrade to v10.

     We have to see where development is on 9. If there's an OS compatibility update to the upcoming Ventura it might be possible.

    List all the specs of your system including how the monitors are connected and what software on which monitor you're capturing so we can see if we can reproduce just in case we do an OS update. Again the issue with cursor interaction is usually OS related. A change in the OS usually requires us to make changes in ScreenFlow which is why it's working in 10 but not 9 as the latter doesn't have the changes done to 10. Keep in mind if an OS update happens it would be this fall at the earliest.

      Bob Mann-Francis While the developers haven't yet decided if they'll be a ScreenFlow 9 update if needed for Ventura (depends on the changes in Ventura) there won't be any additional fixes for ScreenFlow 9 that were done in 10. They would encourage you to upgrade to 10 given the fix.
