Using Second Monitor causes system to loop between displays

I use Zorin OS 16 with dual boot on a Win11 Laptop. When I connect a second monitor display. Zorin OS turns one display "off" and the second one "on" and vice versa. This doesn't stop. It loops between two monitors.
Thank you in advance.

Can you please post the terminal output of

sudo lshw -C video

Are you using Nvidia Graphics? If so, please try changing the driver to a different one. You can launch Software & Updates then the Additional drivers tab.
I am using the 525 Proprietary, as it works much better than the 535.

I don't know what graphics the PC is using. Is thereca command to check that?

I found the cause of the problem.
I switched the power source from my laptop USB port to electrical outlet. I guess my laptop wasn't able to provide power to both monitors. Interesting.
