There seems to be a lot of trouble with monitors not waking from sleep. Is there any definitive information on this problem?
I am having a problem with at least 4 UD-ULTCDL devices not waking the monitor connected to the port labelled 4K.
Each using a Microsoft Surface Laptop 3.
Having disabled the “USB selective suspend” settings, both on battery and plugged-in, the problem is partially eliminated. Now when Windows 10 is locked and unlocked the 1080p BenQ monitor wakes up as expected.
However the monitor still fails to wake-up when the Windows laptop wakes from sleep.
It becomes necessary to disconnect and reconnect the HDMI cable as others have reported.
I see the Plugable debugging tool is regularly recommended on this forum, but surely the problem is well understood by someone now???
The latest DisplayLink software is installed.
What other workarounds exist?
