Thank you for the additional information. Since it works on USB 2.0, the behavior is probably caused by the USB 3.0 controller drivers on your system.
If you’d like us to check the driver version and suggest updates, we will need to look at some system log files.
Can you please download and run our log-gathering tool from the page below:
Please run the tool after you have woken from sleep mode with the monitor connected but not awake. It will save a .ZIP file to your Desktop. Please email the .ZIP file to email@example.com, Subject: Ticket 137878
We’ll have a look at the logs and determine if there are driver updates that might help.
