Set Ubuntu 22.04 Resolution in Hyper-V

Here are two ways to set the resolution of Ubuntu 22.04, when virtualizing in Hyper-V

Method 1

Run this command in PoweShell. note:Change Ubuntu to the name of your virtual machine.

set-vmvideo Ubuntu -horizontalresolution:1920 -verticalresolution:1080 -resolutiontype single

Scaling can also be set in bash uing this command.

gsettings set org.gnome.desktop.interface scaling-factor 2

Method 2

Edit grub

sudo nano /etc/default/grub

Modify GRUB_CMDLINE_LINUX_DEFAULT= with video=hyperv_fb:1920x1080 note: I usually remove quiet splash.

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash video=hyperv_fb:1920x1080"

Finally update grub and install linux-image-extra-virtual

sudo update-grub && sudo apt install linux-image-extra-virtual -y

Finally reboot.
