virtualbox.org

Hello
My Hostsystem is Kubuntu 13.10 x64 and i have Virtualbox 4.3.2 installed. My Guest OS is Windows 8.1. But I need on my Guest System a Full HD Resolution.
I have tried to set, the following command:
VBoxManage setextradata "Windows 8.1" "CustomVideoMode1" 1920x1080x32"
But there is no change into the Resolution Properties in Windows 8.1

What can I do to have on my Guest System a Full HD Resolution?

Please Help me.

Remove the CustomeVideoMode1
Install the guest additions (in the guest) and then use the host+F toggle to go in and out of full screen.

Thanks! That works!!!
