Solved HYPER-V - cannot resize console screen

Hi folks
running Windows 11 HOST and installing a Linux VM (could be Windows - same prob)

The console screen can't be re-sized e.g :


But in Full size -- it then only has one small display -- I want 1920 X 1080

Works via RDP but I don't really want to use RDP.

Any ideas

Cheers

You can only resize the window of a Hyper-V VM when connected to the guest in an Enhanced session, and that is only available as an option if the guest is a Windows Pro edition, or higher. For a Windows Home or Linux guest the window size (and full screen size) is fixed at the resolution set within the guest OS. Enhanced session is greyed out and the only option in the VM connection window is 'zoom'.



So to get your desired 1920x1080 resolution you'll have to set it within the VM itself. For a Hyper-V Linux VM that requires editing grub.

1) Open Terminal
2) Type: sudo nano /etc/default/grub
3) Find the line starting with GRUB_CMDLINE_LINUX_DEFAULT, and add video=hyperv_fb:[the resolution you want].
So my line ends up looking like this: GRUB_CMDLINE_LINUX_DEFAULT="quiet splash video=hyperv_fb:1366x768"
4) Write the changes and quit nano
5) Run: sudo update-grub
6) Reboot the virtual machine

Works for me...

On Ubuntu, you can set up installation to use enhanced mode.

If you cannot use enhanced mode for Debian, you can set it up by making a linux modification.


Same works for Debian as well.

Thanks Guys

Good info
Funnily enough once I updated DEBIAN with the "development repos" and did apt upgrade I was able to get full 1920 X 1080 resolution.

(I was using KDE desktop BTW on Debian 11).

Another partial solution is in the HYPER-V console view is to select "Manual Zoom" which works reasonably but you can't set it too large as the vertical screen won't show the whole thing -- around 125% is OK.

I'll now mark this as solved.

Networking is now OK too -- Bridged networking is easily enough done so full access to the VM from OUTSIDE the host.

Tunnelling with Putty and 8080 port access works brilliantly too from over the "public" internet,

I like the speed of HYPER-V on Windows -- and the fact that the VM can run in the background so users can logon who don't have Windows user accounts on the Host system.

Thanks "peeps"

Happy new year to all.
