Changing Screen Resolution

If you install Linux Mint inside a Hyper-V virtual machine, you automatically get all the integration components and virtualized drivers, including the Hyper-V video driver.

However, if you try to change the screen resolution inside your virtual machine you will notice something odd: There is only one choice!

Luckily, you can change the screen resolution. Just not here. What you need to do is:

• Open Terminal

Type: sudo nano /etc/default/grub

• Find the line starting with GRUB_CMDLINE_LINUX_DEFAULT, and add video=hyperv_fb:[the resolution you want]. The resolution I want is 1280x720. So my line ends up looking like this: GRUB_CMDLINE_LINUX_DEFAULT="quiet splash video=hyperv_fb:1280x720"
• Write the changes and quit nano.
• Run: sudo update-grub
• Reboot the virtual machine and get the resolution that you want!
