Troubleshooting • The orientation of a second 16:9 screen is not activated

Hello, I am faced with a problem that I am having trouble understanding. I currently have a RaspberryPI 4B with a 16:10 (1920x1200) screen which is plugged into the first port and a second 16:9 (1920x1080) screen which is plugged into the second port. I can't get the second screen to keep the left orientation.

My two screens are currently connected with micro HDMI to HDMI cables.

I started by doing it with the ScreenConfiguration, but it doesn't work.

I then tried by creating the file ~/.xsessionrc by adding the following command line: xrandr --output HDMI-2 --rotate left, it still does not work.

I then tried with a bash file in the /etc/xdg/autostart/ directory, making sure to make it executable (with chmod +x), still nothing.

However, the screen rotates if I run the command line: xrandr --output HDMI-2 --rotate left, but remains in lanscale resolution.

I'm wondering if it's not because the RaspberryPI isn't made to handle screen orientations that don't have the same aspect ratio, but I would find that really strange knowing that Windows does this without problem and knowing that it can display a total resolution of 4k.

Thank you in advance for your help!

Jonathan.
