Adding more video modes

To add custom video modes for selection from the Screen object:

  1. Ensure that the VM has been shut down.
  2. On the host, open a command prompt or terminal, and type the following:
    VBoxManage setextradata global GUI/MaxGuestResolution any <Enter>
    VBoxManage setextradata "<VM-name>" "CustomVideoMode1" "<custom resolution>" <Enter>


    <VM-name> = name of ArcaOS virtual machine
    <custom resolution> = the desired resolution, e.g., 1366x786x32
    <Enter> = the <Enter> key (do not type this)

    and where all typed parameters are enclosed in quotes.

  3. Restart the VM and go to the screen object. Select the newly added resolution, and restart the VM.

More information concerning custom video modes may be found in the VirtualBox documentation.

You may add up to 16 custom video modes using this procedure (CustomVideoMode1…CustomVideoMode16). Adding and selecting a video mode which matches your display’s native resolution should result in a full screen VM with no filler bars and 1:1 scaling.
