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. Ubuntu Screen Display

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?

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

Dual Monitor Setup is working.
