I use 2 external displays on my work computer. My MacBook Pro (15-inch, 2018) connected with two USB-C devices connected:
- a Dell docking station: Dell WD15 Monitor Dock 4K with 130W Adapter, USB-C, (450-AFGM) that connects my Samsung external monitor, and it powers my Mac.
- Cable Matters USB-C Multiport Adapter with Ethernet that connects to my Dell external monitor, my Ethernet connection.
When my Mac wakes from sleep (while both hubs are connected), quite often my Dell monitor 2408WFP does NOT reconnect. Clicking the "Detect Displays" in System Preferences > Displays does not detect the Dell display, even though it is plugged in and turned on.
My frustrating workaround is to physically unplug the "Cable Matters USB-C Multiport Adapter with Ethernet" from the Mac. Wait about 5 seconds. Then I physically plug the "Cable Matters USB-C Multiport Adapter with Ethernet" back in to the Mac. At that point the Mac notices that the Dell display is available and it connects, as expected.
Does anyone know a good KM solution to wake the Dell display and automatically reconnect after waking from sleep?
As a possible solution, is there a macro that can:
- simulate "unplug" "Cable Matters USB-C Multiport Adapter with Ethernet" from the Mac,
- pause 10 seconds,
- simulate "plug-back-in" "Cable Matters USB-C Multiport Adapter with Ethernet" into the Mac
Here are some of the details of my 3 displays that could help in script triggering...
