When running VirtualBox guest in the full-screen mode in an external monitor attached to a laptop computer (HDMI) how can I choose the external monitor native resolution in the guest OS?
Only the internal screen maximum resolution (and lower resolutions) seems to be available. My external monitor native resolution is 1920 x 1200 (aspect ratio 16:10) and the internal screen native resolution is 1920 x 1080 (aspect ratio 16:9).
I've tried to re-install Guest Additions, switched between normal and full-screen modes,
VBoxManage setextradata "Windows 10" "CustomVideoMode1" "1920x1200x32"etc. but nothing helps.
- Host: Dell Precision 7510, Radeon HD 8890M, Debian Linux Stretch 64-bit, Xfce 4.12, VirtualBox 5.2.18
- Guest: Windows 10 Pro 1809 64-bit, VirtualBox Guest Additions 5.2.18
Kind regards,
Harri
