Re: 2. In what way is it disregarded? If we cannot replicate a problem here, then it's almost impossible to fix it, and we've never been able to replicate anything like this. Does working through the linked document help in any way?This has been my experience with the Pi4 as well. That when you reboot, it often comes up trying to write to the wrong monitor. When this happens, I just reboot it again until it comes up right.
Some notes:
1) My overall solution is to reboot the Pi4 as infrequently as possible. My current uptime is about 1 year. Basically, it gets rebooted only when we have a power outage (one long enough that the UPS doesn't cover it).
2) I've noted this behavior on this board on this forum a few times in the past. As expected, it just gets pooh-pooh-d.
3) As one responder says, it does probably have to do with the hotplug detection not working 100% correctly in all cases. In my case, I have a long (25 ft) cable connected to HDMI1 that is currently not plugged into anything at the other end. So the cable is kind of "non-terminated" - maybe that causes it to think there is something there when there isn't. When I did have a monitor connected to that cable, it was a sorta flaky monitor that never really worked 100% correctly and did eventually die (so I unplugged it and threw it away).
Re.3 A 25ft HDMI cable is a LONG cable, and you will get signal loss over it, so I would also check with a good quality shorter cable. Since its not plugged in right now though, I would not expect that to be a cause of problems.
