I just drag the VirtualBox window to the size I want but you can run it full screen if you wish, which is what you suggest by matching the host screen resolution.
Also make sure the Video memory is set at max.
Virtualbox Windows virtual machine has only a few display resolutions

I am running Windows 10 on a virtual machine, using VirtualBox. When I tried to change the display resolution it only gives me a few options, which are all 4:3 or 5:4. They are:
800x600, 1024x768, 1152x864, 1280x1024, and 1600x1200.
My PC has a monitor of 1920x1080 display, so is it possible to change the VirtualBox VM to match the screen display resolution?

2021-07-01T18:06:50+00:00 Yes, I just installed the VirtualBox guest addons, as well as the extension pack. Right now I could still see the same resolution options though, but no other options for wide screens. Am I supposed to change the settings of the virtual device?

Have you installed Virtualbox drivers? I believe the name for the same is Guest additions.
