    Hyper-V, Windows 10 guest VM, console resolution limit 1920 x 1080


    I have a Windows 10 (10.0.18362) Hyper-V host and a windows 10 (10.0.18363) guest VM.
    The guest is a Generation 2 enhanced VM.

    It would appear that the recommended way to connect to the guest is via RDP.
    Unfortunately I can't use this method, I need to connect to the console.
    The reason is because I have a VPN client that won't run when you connect via RDP.

    My issue is this: the console uses a video driver (hypervideo.sys) that has a maximum resolution of 1920 x 1080 and I would like to use a much higher resolution on my 4K monitor.

    Is there an alternative video driver that I can use that will allow a higher resolution than 1920 x 1080?

    Hi there
    you could try using the video passthru although that normally needs 2 graphic cards - one for the Host and one for the VM - or 2 outputs on an existing graphics card. Then on the VM you can use the Native video driver --actually this way will improve the graphics capability of the VM significantly.

    For Console connection install openssl on Windows if you don't like RDP -- also for simple file transfer etc you can install filezilla as well as an excellent FTP client,

    Thanks Jimbo.

    I only have the one monitor right now, but maybe it's worth me pursuing your solution.

    Just to clarify, when I say 'console' I don't mean command console, I mean a connection directly to the VM UI as opposed to RDP.

    Thanks.

    Hi there

    You can still use dual (or more) HDMI outputs even if you have only 1 Monitor.

    Use an HDMI switching unit if you only have 1 monitor -- just switch the 2 (or more) graphic outputs into the HDMI switching box and switch between them.

    Manual ones are cheap --don't bother with expensive "Auto" things -- also the cheaper (usually the Chinese / Taiwanese / Vietnamese unbranded ones) ones won't have DRM problems with HDMI cables etc. OK you'll need proper HDMI cables between computer-->HDMI switching box-->monitor of course.

    For easy management simply set Windows Host to have openssh on it (add features) and from the VM for any Host commands use ssh - however just manually switching the HDMI connections to the monitor should work perfectly OK.

    Installing SFTP/SSH Server on Windows using OpenSSH :: WinSCP

    If during this "Cova -19 Lockdown period" you are stuck at home for long periods and want to try something new -- have a go with this !!!

    Use the opportunity to experiment with something new !!!

    (Actually this type of solution is so much easier running the HOST as a Linux machine and running the Windows VM's on it -- KVM/QEMU Hypervisor (Libvirt) runs brilliantly like this and passthru of graphics is no problem for Windows VM's --also Linux systems can easily run headless so even easier. !!!!)
