Correct resolution in VirtualBox

I have to set the correct resolution in the config. I was fixed to a 640x480 resolution.

With xrandr i can view the possible resolutions and with xrandr -s 1920x1056 i cloud set it manually, fwvm2 did not adapt fully to the new resolution.

Therefor i have a xorg.config.

/usr/local/etc/X11/xorg.conf.d/monitor.conf
