ASUS VA249 HE monitors on ASUS PRIME Z690-P D4 Motherboard

I have dual monitor setup. Both monitors are Asus models VA249 HE. They are connected to the Display and HDMI ports of the Asus Motherboard. I am running Ubuntu Ubuntu 22.04.1 LTS.

When I boot with one monitor the options to control the display are limited. I can't adjust the resolution.

If I plug both monitors I get a mirrored display. The option to extend the display is not available.

How I can resolve this please?

Link to the Monitor Specifications -- VA249HE

Additional Information

The video is on the Intel CPU.

According to Intel is it Intel® UHD Graphics 770

"Unkown Display", your system is not recognizing the display you are using. Have you tried installing available drivers? Look into it and update your question. I see that ASUS does not provide drivers for that display, but maybe some third-party does? Beware of the risk of using those.

I can plug the monitor into my Windows computer (migrating from a Windows environment to Ubuntu) but other than that I don't really know how to go about this. In Windows it is transparent and I never had to deal with drivers.

Take a look at this: https://askubuntu.com/questions/1069451/ubuntu-18-04-displays-issue-unknown-display . Update the question if any of the answers helped. Have in mind that Ubuntu is not Windows, drivers may differ, that's why maybe Windows works out of the box with your display config.

I followed the link. I updated the original question to add clarity. Point to note: The video is Intel on the CPU. I also added the output of various commands that the poster of the link you shared had mentioned.

I followed the guide at How to Identify & Find Graphics Drivers for Linux and the monitor is identified.

Dual Monitor Setup is working.

Glad you solved your problem. Seemed like a clear problem related to drivers. I should've asked (or at least thought) about your graphics card, experience for the future, though.

It makes one wonder how the drivers of a company such as Intel would not be packaged and detectable out of the box. But the community was fantastic.

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.
