Default ThinkPad Hybrid USB-C - Macbook Air 2020


I just got a dock home from my workplace today, brand new, for my Thinkpad notebook T495.

everything works fine when I use my Thinkpad T495 with windows 10.

My Monitor is Asus ROG PG279Q 2560x1440- 144 hz

but when I try to connect the USB-C to my MacBook Air and close the lid of the MacBook, the display flashes black for 1-2 seconds about every 20-30 seconds.

if I keep my lid open, there is no issue.
i have been in "about Mac" and "system repport" and then "Extensions" I can't find a text called "Display link" at all, as I read you should be able too.

i am running osx version Big Sur 11.1

i have the displaylink software running in the upper right corner in OS X telling that "monitor detected" and login screen extension status: installed.

Thank you for contacting our support.

If you are using a DisplayLink Manager v1.x then its current limitation is lack of Clamshell mode support. This functionality is available in classic drivers only for Catalina. The only workaround we have for Big Sur is to keep the laptop lid open.

We are working with the OS vendor to add this functionality to the future releases of the software but it is not available just yet.

Please check the following article for more information:

Best regards,
