I have windows 10 guest os and it scales fine when connecting using virtual box, but when connecting via RDP the screen is windowed, But if i run the same guest os headless (BoxManage.exe startvm "" --type headless) then i get fullscreen in rdp.
Am I doing something wrong? are there some settings to adjust in the VBoxVmService?
I have added ("C:\Program Files\Oracle\VirtualBox\VBoxManage.exe" setextradata “” CustomVideoMode1 2560x1440x32) but with no result
