Dynamic resolution allows the virtual machine to change resolution to match the current window size (including full screen window). It it only supported on QEMU backend virtual machines and requires guest tools to be installed.
- In the virtual machine configuration, make sure that “Auto resolution” is checked.
- Install the guest tools on Linux or Windows.
- Reboot the virtual machine.

iOS When you change the display orientation, it will request the guest agent for a resolution change. On iPadOS, resolution change will also be requested for Split View, Slide Over, and window resizing in Stage Manager.

$ xrandr --output Virtual-1 --auto
