Issue when wake from standby

[miller5369]

I have the same issue. I have two DisplayLink monitors controlled over DisplayPort -- one always wakes from sleep and the other doesn't. It is still recognized as a monitor within the Displays control panel but nothing will cause it to show the image until you reboot. It's similar to your situation where a reboot will take care of it. Hope that gets fixed.

Does it start working properly when you select a mode for the DisplayLink-attached screen? Please go to System Preferences -> Displays, grab all windows and select a mode for the screen that is recognized but shows nothing. If that fixes it, then it is a known problem which we already fixed.

Thanks,

I have the same problem and this doesn't fix it. System prefs sees the screen. Can still drag things onto it, but its completely black and only a restart will fix it. Tried changing resolutions and refresh rates; nothing.

Even still, having to reconfigure the screen every time you open your laptop would be an absolute pain, even if it did work!

Tried your workaround without success. If the computer return from the standby with the DisplayLink already connected, do not recognize the 3rd monitor. If I go to the Display > Arrangement shows only 2 minitors (Notebook + HDMI).

Only after an reboot without the displaylink connected and connect after login that work.

Tried multiple times in different machines, do NOT WORK all the times.
