Can you please gather logfiles while this is happening?

To do that you can follow the article here: How to Report MacOS Issues to DisplayLink

Thank you

I just sent the email to support team. However ill send here the updates and STR the error:

My Setup:

- MacBook Pro 16 Inch - Chip M1 PRO / Monterrey 12.4
- Screen: SAMSUNG C27JG5X
- Screen: SAMSUNG C27fg70
- Screen: Dell Up218Q
- Dock: Plugable UD-3900PDZ
- Ipad 9th generation - iOS 15.4

STR:

1. Connect your screens via DisplayLink:
In my case:
- Main screen on HDMI 1:*SAMSUNG C27fg70- 2 screen on HDMI 2:*SAMSUNG C27JG5X- 3 screen on HDMI 3:*Dell Up218Q
- My laptop*is closed in a vertical dock:*2. Try to connect the IPAD via UniversalControl. Moving the mouse to*the side where the iPad is but no luck. There is no indication that the iPad is there to connect.*
3. I can connect the IPad as an external*monitor (4 in my case) but I can not use the keyboard/mouse to control it.

I found a way to fix the issue:

1. Disconnect the monitors from the DisplayLink
2. Open the laptop*
3. At this moment*i am able to use the iPad in UniversalControl mode (I can use the*keyboard and mouse)4. Connect the DisplayLink dock again
5. Close the laptop
6. The iPad continues working on UniversalControl. At this point I can use the feature w/o problems
7. But if I disconnect the ipad or the DisplayLink Dock the feature stops working and I need to do all the process again.

I hope this can help to fix the issue or understand what i'm doing wrong
