Hypervisor Full Screen Issue

Followed the steps to get full screen as common shown online in other threads, including Copilot below. Nothing works.

To make your Hyper-V virtual machine full screen on Windows 11, you can follow these steps:

1. **Enable Enhanced Session Mode**:
- Open the **Hyper-V Manager** from the Start Menu.
- Right-click on your host machine and select **Hyper-V Settings**.
- In the left pane, select **Enhanced Session Mode Policy** and check the box for **Allow enhanced session mode**.
- Then, go to **Enhanced Session Mode** and check the box for **Use enhanced session mode**.
- Click **Apply** and **OK**.

2. **Configure the Virtual Machine**:
- Right-click on your virtual machine and select **Settings**.
- Go to **Integration Services** and ensure all services are checked.
- Click **Apply** and **OK**.

3. **Adjust Display Resolution**:
- Start your virtual machine.
- When the VMConnect window appears, you should see a slider to adjust the display resolution. Move the slider to your desired resolution.
- Once the virtual machine is running, go to **View** in the toolbar and select **Full-Screen Mode**.

These steps should help you achieve a full-screen resolution for your Hyper-V virtual machine on Windows 11. For more detailed instructions, you can check out this [guide](https://www.thewindowsclub.com/how-to-change-hyper-v-display-resolution-in-windows).

I did everything, restarted HV and VM, rebooted my laptop even. Running latest stable Windows 11. I'm using Zorin OS as the VM o/s. When I go to full screen mode in the VM, it shrinks the actual Zorin desktop to a smaller screen, despite setting it to highest resoution of 1920x1080.

How To Change the Resolution of an Ubuntu Hyper-V Virtual Machine -- Virtualization Review

You can't change the screen resolution in an Ubuntu VM hosted on Hyper-V from the GUI. Here's a simple workaround.

Thanks but that didn't work. It's a 10 year old article from 2014 too, so probably not up to date.

@Bree's solution is the correct one - used it several Linux versions.

If I remember correctly, it was you that originally put me on to it...

Yeah - I think you may be right. That is why I knew you were right LOVL.

PS - I use nano rather than vi editor to edit the grub file - I find it easier to use.

Hi folks

That method won't work for some of the latest distros that use systemd as boot manager rather than grub (or grub2). However things like Opensuse and Fedora with 6.11.X kernels work straight OOTB with Hyper-V. It also depends on what you use as a window manager (the GUI) - if using X11 or Wayland - on some distros Wayland isn't yet 100% fully working in all cases - again opensuse, and Fedora work straight OOTB whether at login time you select X11 or Wayland.

If using things like Archlinux where you have to configure your own system much more it also works on 6.11.X with Wayland as well but you must ensure the whole Wayland package and all of its dependents are installed.

What is problematical with Wayland in the VM is if from the VM you want to connect (full screen) to a remote Windows machine using an rdp type of protocol. That's a Windows problem rather than Linux as RDP doesn't work with Wayland. It can be done via setting up a VNC server on the Linux VM but that's far too much a hassle while X11 still works on Linux -- note too that X11 is being deprecated in the near future .

BTW nano is far superior to vi -i'd install that as a matter of course if the basic package doesn't include it-- plus also install ntfs-3g if you want full read / write access to Windows ntfs disks.

I am not sure, but sounds like there is a "keep aspect ratio" or similar setting. You need to change it to stretch or full to fill the screen. Probably not possible in Linux with the open drivers, but if you would install proprietary drivers and had access to some graphics control panel, this should be possible from the screen settings. You could also try switching from monitor scaling to GPU scaling and vice versa.

@cereberus

Here's Opensuse tumbleweed Linux (kernel 6.11.X) at full screen on a monitor with max 1920 X 1080 -- full HD on Hyper-V-- can also test on a bigger one later but no prob with full screen with the monitor it's connected to.

From the fast fetch you can see the video is 1920 X 1080 which is full screen fior the monitor I'm using.



BTW I can get better performance if using 4X virtual CPU's rather than the 2 done by using Hyper-V in "Quick create VM" but this was just a test for full screen availability.
