Run Virtual Box in full screen mode for optimal visibility.
I've tried this many times, but I'm not sure how to change the window size for a VM. I just need the windows to match my monitor's resolution.
Optimize the view?
In system or virtual machine configurations It might be related to OS or VM adjustment settings
You just resized the host window to increase its size.
The virtual machine needs Guest Additions enabled to access scaling features.
Ok thanks
It only affects the appearance of the window, not the actual operating system's resolution.
The guest operating system is not specified, but extensions are available for installation.
