I am using the two LG 27UD58 monitors with two Displayport cables. When I wake my MacBook Pro (2019) out of sleep mode, often only one monitor is recognized and comes back on. I will have to unplug the USB-C cable from the MacBook, and then plug it back in, to get the second monitor to be recognized and turn back on. Any help you can offer so that I might better understand what is occurring is appreciated.
Thank you for contacting Plugable support! Sorry to hear about this issue. I’d be more than happy to assist you.
Since these displays are connected directly via DisplayPort, I wouldn’t expect you to encounter this sort of behavior. Normally, this kind of behavior is only seen on occasion when using a DP to HDMI conversion for the displays.
We have a troubleshooting tool that helps us find out what is going on in situations like this. Please plug the dock with your displays attached into your computer, then go to this page and follow the instructions there:
