    @Dylan Begin with the first instructions and open up a terminal. This can be found in your applications. Sudo vi /etc/default/grub is opening a file located in directory at /etc/default. Vi itself is a text editor, which allows you to make changes to files. Now you need to use vi to find the line stated above. You then add the line given, or whatever your target resolution is. He gives the command to save and exit the file. Then run the last commands and reboot.

    I'm sorry I have no clue how to "write changes to the file". As a new ubuntu user these instructions seem to assume a lot. Can you please clarify? Also, what should one do if one has inadvertently started multiple instances of this vi /etc/default/grub running in the background because one had no clue that simply exiting the terminal would not kill the instance? Thank you

    Didn't work at all, but I'm not on Ubuntu. I'm on Chakra . . .

      What resolution did you use? Current maximum resolution is 1920×1080 for the hyper-v display driver. Here is what grub command line should look like:

      GRUB_CMDLINE_LINUX_DEFAULT="quiet splash video=hyperv_fb:1920×1080"
