22.04. If I plug in a external high res monitor I do not get video output

So I was trying to configure 2 monitors. I wanted to use the new 34" as an extra (not simultaneous) workspace. When I accepted my changes, both go blank. I can unplug it and laptop display works fine.

A couple basic searches and '~/.config/monitors.xml' no longer seems to exist. Can anyone tell me where the monitor config file is, so I can fix my screw-up? In an attempt at getting an answer, I can add the following. I ran the following in terminal. First attempt was local laptop display, second attempt was blind (It all went black when I plugged in the bigger screen). I do not understand what this command is telling me yet, I am still going through the instructions. Does this help tell anyone what I need to fix?

I don't understand the downvote on this question - it's just asking about the location of a configuration option and how to reset it. All the needed info to answer the question is likely already there.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
