My 2020 MacBook Pro is connected to an external monitor using the USB-C Digital AV Multiport Adapter (using HDMI). After I wake my MBP after being asleep, it does not recognize the external monitor. I have to disconnect the USB-C and reconnect, and then all is fine. Never had this problem with my old MBP. Anyone else have this problem?
MacBook Pro 13″, OS X 10.11
It didn't solve for me. I've been doing it for the past 3 days, it keeps happening at random.
My guess is that it tailors with the other problems on the USB-c port. 10.15.6 doesn't solve either.
Of note: I don't have those problems with BootCamp. So it's definitely a macOS problem.
Solved by Apple Support. Hold power button down for 10 seconds, wait a few seconds and restart the computer. It resets the ports and other system management tools.
