Changing Resolution of Linux Mint on Hyper-V

Ensure your not using the Hyper-V RemoteFX 3D video adapter.

  1. Open Terminal
  2. Type: sudo kate /etc/default/grub
  3. Find the line starting with GRUB_CMDLINE_LINUX_DEFAULT, and add video=hyperv_fb:[the resolution you want]. The resolution I want is 1920×1080. So my line ends up looking like this: GRUB_CMDLINE_LINUX_DEFAULT=“quiet splash video=hyperv_fb:1920×1080″
  4. Write the changes and quit kate.
  5. Run: sudo update-grub
  6. Reboot the virtual machine
