I tried -device VGA,vgamem_mb=32. I did not see any resolution above
1080p on a Windows 10 guest.
virtio-vga has many more resolutions available, it was just missing 4k.
I have the virtio-win-0.1.190 driver pack installed.
I don't use qxl, because it makes the Windows GUI sluggish for me. I
don't have problems with VGA or virtio-vga.
