Suppose the monitor is plugged into Outlet A when I turn on the computer; I have to unplug it and put it in Outlet B before it will work. I use the computer for a while and then turn it off. Next time I turn it on, the monitor is already plugged into Outlet B, but now it won't work until I unplug it and put it in Outlet A. So both outlets work equally well; the key point is that I need to change the outlet after turning on the computer. Changing it before turning on the computer doesn't work. Neither does unplugging the monitor and plugging it back into the same outlet again. Very occasionally, I have to move it to a third outlet before it will work -- but again, which specific outlet is the third doesn't seem to make any difference.
The monitor itself is not the problem. Other monitors used with this computer exhibit the same strange behavior. This monitor used with other computers behaves normally. All the outlets work completely normally if I plug anything other than a monitor into them.
I've had a computer technician and an electrician look at the problem. Neither of them has a clue what's going on. I'm posting this here on the off chance that any of my readers can solve the mystery.

That is utterly bizarre. For sake of thoroughness, did the electrician test the monitor power cables? Are the outlets in the wall or are you using a power board?
In this case, I think CGPT is actually correct. The computer clearly is the source of the error, not the monitor or the outlet. https://chatgpt.com/s/t_6931e4b8d5ac819193d58ae8ffdca2b0
Maybe you and I owe the non-thinking machines an apology?
I'll try plugging both devices into a power strip and see if that solves the problem.
Using a power strip has indeed solved the problem. Thanks to Leo and, begrudgingly, to the fake intelligence he used.
Can’t resist. This randomly came across my X feed today TWICE and I just have to post it. The first comment describes essentially the same problem you had with your monitor. https://x.com/onscreenlol/status/1996982375876575584?s=46
Without a Twitter account, I can only see the original post, not the comments, but I'll take your word for it.
I spoke too soon. With a power strip, the monitor now sometimes works without switching the outlet, whereas before it never did.
