+Set the initial graphical resolution and depth.
+
+This setting may be masked by guest firmware temporarily.
+
+On PPC and SPARC, the guest firmware will configure the display from
+this setting, and the guest OS will inherit the display resolution
+and depth.
+
+On x86 and ARM, if the guest firmware is an edk2 (UEFI) platform,
+the firmware may initially configure the display according to its own,
+persistent, independent settings. The guest OS drivers, once loaded,
+should adhere to "-g" however, for virtio and qxl adapters.
