Macbook Air M1 connect to external LCD Monitor through USB-C hub
I have 3 Macbook Air M1 (base model), all connected to its external LCD monitor. So, basically 3 MBAs connects to 3 LCDs through 3 USB-C hubs. They all have similar issues. On the other hand, my old MBA (Mid 2013 base model) does not have any of the following 3 issues.
The 1st issue is most server, around once in a few days. It goes beyond annoying. Both the external LCD and MBA's display turn to pink flash then crash and reboot. Sometimes it doesn't have anything, directly jump into reboot. The problem is, it is unpredictable. It can happen anytime without any prior symptom. I can't recreate the situation as well.
The 2nd issue is, from time to time, the external LCD turns to all black for less than a second, while the MBA's display still on. This happens like once or twice a day.
The 3rd issue is the external LCD will start 1 or 2 seconds behind the notebook display after wake up. This happens every single time.
There is no way to reset NVRAM or PRAM for M1 chip machine. So I don't know what to do. Welcome any suggestion.
