# Problem 1: get full 1440p resolution on my 2518 (as the VM's primary display)
# initially I tried 
VBoxManage setextradata Windows\ 8.1 "CustomVideoMode1" "2560x1440x32"
VBoxManage setextradata Windows\ 8.1 GUI/LastGuestSizeHint 2560,1440
# as well as some other stuff I don't remember, and it worked. I think that second line did the trick.

# Problem 2: get portrait orientation 1080x1920 on my 2414 (as the secondary display)
# this time I followed this: https://winaero.com/blog/set-exact-display-resolution-in-virtualbox-virtual-machine/
VBoxManage setextradata global GUI/MaxGuestResolution any
VBoxManage setextradata Windows\ 8.1 "CustomVideoMode1" "2560x1440x32"
