[PVE-User] Maximal resolution with -vga std in windows-vm

[Nils Privat]

Hello,
i set up an windows vm (server 2016 and win10) with the default option -vga
std. Inside the VM i cant edit the resolution, neither higher or lower
(fixed resolution: 800x600). Thats a bit low and as i understand the -vga
std allows resolutions higher than 1280x1024 (see:
https://wiki.gentoo.org/wiki/QEMU/Options) but as i said i cant change it.
I do not installed any graphic-drivers, only virtio-network (NetKVM),
virtio Balloon, virtio guest-agent and virtio vioscsi.

I prefer to use -vga std. and not vmware or qxl where extra drivers are
required.
Any suggestions?
Thanks
