MacBook Air (M1) does not detect monitor after reboot
 

Hello,

I'm using macOS Version 11.2.2 (Build 20D80) and I am using the Dell D6000 docking station which I purchased yesterday. I'm experiencing the following issues with DisplayLink software and/or hardware:
DisplayLink driver does not detect my Dell P2419H monitor when I reboot my Macbook Air 2021 (M1). :( I then need to disconnect the dock and connect back again each time to detect it. Then again when I shut down my macbook and start again the issue comes back. I have tried both HDMI cable and DisplayPort cable. :mad: I am using the latest DisplayLink driver v1.4 and I have done all the steps like giving permission for screen recording etc. Any idea why I am having this issue?

Thanks
Raj

I have already created topic about this issue: https://www.displaylink.org/forum/sh...1876#post91876

It's answer from official support (Kate):
It looks like the bug is happening on the OS side, As detection is unrelated to our software.
It is something that we've already reported to the OS vendor but did not receive any updates yet and there is nofix as of now unfortunately.


Another words after Macbook can't detect Dell D6000 as usb device after reboot.

Thanks Dmitry. I have also logged a ticket with DisplayLink and this what I got back:

Thank you for reaching out!

Please check if the docking station or adapter that you have your monitor connected to is detected after starting the computer.

If your device does not work, the first thing to check is that the DisplayLink device has been detected by OS X. This can be done by checking that the DisplayLink device appears in the System report. To do this:

Choose "About this Mac" from the Apple menu on the top left corner of your main screen
Click on "More Info..."
On Lion and later: click on "System Report…"
The System Information application will open
Select the USB information from the Hardware category as shown in the screenshot:

In the USB devices list, locate the DisplayLink device. Make sure that it says DisplayLink (UK) Ltd. as Vendor ID.

If no devices are shown, then follow the steps below to try and make the device appear in device manager.

Unplug all cables from the device, then reconnect power (if needed) then the USB cable.
Check the USB port with another device to make sure other devices are recognised.
If using a Wireless USB product, ensure the wireless USB drivers are installed separately. The wireless USB link is not part of the DisplayLink technology and will need separate drivers to be installed.
Check that the USB cable works with other devices.
If using a USB bus powered device, make sure that the device is connected to an externally powered USB hub (the hub has a USB cable and a power supply connected to it). This will ensure that the device an receive enough power from the USB bus.
Try the adapter on another computer.

If it still does not appear in the system report then you should contact the original manufacturer, not DisplayLink, to discuss a hardware replacement of the product.

I hope someone fixes this problem soon.

I have a similar issue - I have two displays. One is USB-c connection, which I have my Dell D6000 and HDMI monitor plugged into (daisy-chained).

After a reboot my USB-C monitor is not recognised. However, everything plugged into that display including the D6000 works fine. I have to unplug/plug the USB-C monitor to get it working.

So I think the OS issue is with initialising / turning on the 1st external display after a reboot.

I am not able to get my two monitors to connect, only one of them will work at a time.

Can you please tell me what is the DisplayLink powered device that you have?
How are your two monitors connected to that device exactly?
