Wheezy VirtualBox guest 1920x1080 resolution

I have Wheezy 7.5 amd64 machine running MATE 1.6.0-3+7.wheezy.  X 
automagically detects my 1920x1080 LCD monitor and the desktop displays 
at that resolution.


The machine also runs VirtualBox 4.1.18-dfsg-2+deb7u3.  I have a Wheezy 
7.5 amd64 MATE guest.  I would like to run the guest at 1920x1080 in 
fullscreen mode, but unfortunately the maximum resolution available via 
Start -> System -> Preferences -> Monitors seems to be 1600x989.


I've also tried creating an /etc/X11/xorg.conf on the guest with monitor 
settings, but that doesn't seem to have any effect:

Section "Monitor"
        Identifier   "Monitor0"
        VendorName   "LG"
        ModelName    "EW224T"
        HorizSync    30-83
        VertRefresh  56-75
        # 1920x1080 59.96 Hz (CVT 2.07M9) hsync: 67.16 kHz; pclk: 
173.00 MHz
        Modeline "1920x1080_60.00"  173.00  1920 2048 2248 2576  1080 
1083 1088 1120 -hsync +vsync
        Option "PreferredMode" "1920x1080_60.00"
EndSection


Any suggestions?


TIA,

David
