will remove all limits on guest resolutions.
VBoxManage setextradata global GUI/MaxGuestResolution >width,height<

9.15 Configuring the BIOS DMI information
The DMI data VirtualBox provides to guests can be changed for a specific VM. Use the following commands to configure the DMI BIOS information:
VBoxManage setextradata "My VM" "VBoxInternal/Devices/pcbios/0/Config/DmiBIOSVendor" "Host BIOS Vendor"
VBoxManage setextradata "My VM" "VBoxInternal/Devices/pcbios/0/Config/DmiBIOSVersion" "Host BIOS Version"
VBoxManage setextradata "My VM" "VBoxInternal/Devices/pcbios/0/Config/DmiBIOSReleaseDate" "Host BIOS Release Date"
VBoxManage setextradata "My VM" "VBoxInternal/Devices/pcbios/0/Config/DmiBIOSReleaseMajor" 1
VBoxManage setextradata "My VM" "VBoxInternal/Devices/pcbios/0/Config/DmiBIOSReleaseMinor" 2
VBoxManage setextradata "My VM" "VBoxInternal/Devices/pcbios/0/Config/DmiBIOSFirmwareMajor" 3
VBoxManage setextradata "My VM" "VBoxInternal/Devices/pcbios/0/Config/DmiBIOSFirmwareMinor" 4
If a DMI string is not set, the default value of VirtualBox is used. To set an empty string use "<EMPTY>".
