My second monitor is not showing up in the display settings using an RTX 3090 nVidia GPU, see the first screenshot, I am using Ubuntu 20.04.

I have tried using all of the drivers shown in the screenshot below,

Running Xandr I see:

The second monitor is connected by display port and has 4K resolution. Any insights on what to try next much appreciated, I'd be happy to give more information.

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.
