Quick tip for boosting resolution in a Ubuntu VM in HyperV
from terminal
sudo gedit /etc/default/grub
Edit or add the the assignment to RUB_CMDLINE_LINUX_DEFAULT
RUB_CMDLINE_LINUX_DEFAULT="quiet splash video=hyperv_fb:1920x1080"
I chose 1920×1080 as this is the current maximum that the Hyper-V machine connection will support and it is less than what my monitor supports, change this to a value that makes sense for you.
After saving run:
sudo update-grub
And then reboot your virtual machine
