Hi,
i have been using an Lenovo USB-C Dock for about 1 ½ years with my macbook Pro.
Two external displays connected via HDMI.
So when i connected to the Hub and closed the Laptop it would automatically switch of the internal display and only use the two external monitors.
Since the Update to Mac OS 11.4. i am having troubles.
At first the external displays would not show ANYTHING. I solved that problem by installing the lates Display Manager (1.4. Build 57.120).
So now the ext. displays show content again but if i close the laptop the displays come back to life after a few seconds bit the internal display is still shown in the control settings as an active display AND the external display are going black every 15-20 seconds.
I tried all the trouble shooting from display Links help page....non of them worked.....
anyone with the same problem? or ideally with a solution ?
Thanks!
best
ben
