16-inch MacBook Pro on macOS Catalina 10.15.5 - Closed Lid/Clamshell mode issue

[OldLnyx3]

Clamshell mode does not work for me. The built-in display stays active no matter what. Additionally, this means that 144hz monitors using DisplayPort will render at 60hz.

When in clamshell mode the machine periodically tries to sleep, and then wakes up again. Very annoying.

None of the fixes mentioned work.

macOS 10.15.4
MacBook Pro (15-inch, 2018)
5.2.4 drivers

I am also having issues with clamshell mode on an 13 inch MBP 2019/4-Port with Dell D6000 attached (one at work, one at home).

Running Catalina 10.15.5 and DisplayLink Manager 1.0.0. The device only has one built in graphics adapter (Intel Iris Plus Graphics 655 1536 MB)

When entering clamshell mode, the system automatically asks for a login, then after login periodically tries to sleep and wakes up on mouse movement. So the screen gets dark sometimes (at least once per minute) and comes back after 3-10 seconds.

Also, the 27 inch display (ASUS PB287QV) which is connected via DisplayPort is an "Unknown Display" whereas in "About this Mac > Displays" it shows with correct name but 41 inch size. So maybe there are handshake issues as well?

I might have solved this issue for me:

1. Reinstalled the DisplayLink Manager 1.0.0 first.
2. Then reinstalled the DisplayLink USB graphics driver 5.2.4
3. Restarted

The screen works just fine without interruptions.
The ASUS is now recognized as 27 inch.

Hello,

Please keep in mind that our DisplayLink Manager App does not support Clamshell Mode at this time. We are actively working on including this functionality to the App but currently it only works with classic drivers and not the application. We do not have any dates set for this functionality to be released yet.

Best regards,
Katarzyna

Any way to circumvent the issue for now?
Or atleast a rough estimate on when this might be resolved?

Clamshell Mode will right now work only in classic driver so version 5.2.4 and earlier. There is no other workaround as of now. As for estimate on when this may be resolved, we are working with OS vendor to get the functionality added but we really do not have any time frame set for now.

Classic driver has to be uninstalled prior to installing DisplayLink Manager App.

I don't know what I did, but it works like a charm with my configuration.* All screens are supported: two displays + one MBP screen. When I close the lid, the MBP screen goes dark and the two other displays work just fine (at home + at work), without the two active screens going dark. So for me, the D6000 supports clamshell mode with your drivers. Even rotation (pivot) works. I really hope it stays this way for a long time.

Thank you for the support on this forum and continuing DisplayLink support for macos!
