manually set virtualbox guest display resolution #380

I'm running i3 window manager on ubuntu 16.10
I'm trying to run a win 7 guest @ 4k res on my xps 15 9550
adjusting the screen by dragging the mouse is not working at all -- the window always auto-adjusts to this 2x4 form factor (odd)

I found this workaround, to manually set the guest's display resolution from the host command line:

vboxmanage controlvm "windev" setvideomodehint 3840 2160 32

I've had the most luck on my setup by making the guest window float, running this command on the host, and then dragging the window to scale the screen.

the dimensions are a bit off still at full 4k though, so to account for the window title bar, edges, and virtualbox icons at the bottom of the window, it helps to remove a bit of the guest screen resolution:

vboxmanage controlvm "windev" setvideomodehint 3820 2130 32
