I had an open thread with you already on this topic, but you closed it out. The problem persists after all of your previous suggestions.
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.
