How to change VM resoulition to higher Hyper-V


I am trying to increase the resolution of the VM window.
However I am not able to find the setting anywhere within Hyper-V manager.

Even in full screen mode I see VM doesnt occupy entire screen. I do remember it asked for resolution during first time set up, but I dont know how to change it now , I want it to be full screen or my custom length x width.

This is how it looks now in Full screen mode , occupying black background

I have tried changing below options with no luck

Hyper-V settings -> Enhanced Session Mode


Hyper-V settings -> Reset Check boxes

Also added below text in config files located at C:\Users\Prateek\AppData\Roaming\Microsoft\Windows\Hyper-V\Client\1.0

  • clientsettings.config
  • user.config
  • virtmgmt.VMBrowser.config
  • vmconnect.config
  • vmwizards.config
<setting name="FullScreen" type="System.Boolean">
<setting name="DesktopSize" type="System.Drawing.Size">
    <value>1920, 1080</value>

  • One way to change your resolution is via the following:

    1. Open Terminal
    2. Enter sudo vi /etc/default/grub
    4. Modify the line with the resolution you want, ex: 1920x1080: GRUB_CMDLINE_LINUX_DEFAULT="quiet splash video=hyperv_fb:1920x1080"
    5. Write the changes to vi and quit, ESC wq
    6. Enter sudo update-grub
    7. Reboot the VM

    --if you can use the "Quick Create" option in Windows 10 Hyper-V, I believe you'll get a better experience and the ability to adjust the resolution on the fly. It doesn't seem that you can configure a manual install to do this.
