You can set a default scale factor for all VMs.

Use the slider to select a scaling factor up to 200%. For multiple monitor displays, you can set the scale factor for individual monitors, or globally for all of the monitors. Scale Factor: Enables scaling of the display size.

You can configure the relationship between guest and host monitors using the View menu by pressing Host key + Home when you are in full screen or seamless mode. As a result, for full screen and seamless modes to work with multiple monitors, you will need at least as many physical monitors as you have virtual monitors configured, or Oracle VM VirtualBox will report an error. However, in full screen and seamless mode, they use the available physical monitors attached to the host. The output of the multiple monitors are displayed on the host in multiple VM windows which are running side by side. Up to eight such virtual monitors are supported. If a guest OS supports multiple attached monitors, Oracle VM VirtualBox can pretend that multiple virtual monitors are present. Monitor Count: With this setting, Oracle VM VirtualBox can provide more than one virtual monitor to a virtual machine. Extra memory may be required if display acceleration is used. A rough estimate is ( color depth / 8) x vertical pixels x horizontal pixels x number of screens = number of bytes. The minimum value depends on the number of virtual monitors, the screen resolution and the color depth of the host display as well as on the use of 3D acceleration and 2D video acceleration. The GUI will show a warning if the amount of video memory is too small to be able to switch the VM into full screen mode. Based on the amount of video memory, higher resolutions and color depths may be available.

As with the main memory, the specified amount will be allocated from the host's resident memory. Video Memory: Sets the size of the memory provided by the virtual graphics card available to the guest, in MB.

The following tabs are available for configuring the display for a virtual machine.
