How to fix HyperV Virtual Machine display taking over the entire screen


In this guide, I will be discussing a recent issue I encountered which is a bit rare. It is about a full-screen virtual machine (VM) session that overtakes the entire screen when I connect to the VM. Windows normally display RDP sessions within a window. If you want to close the RDP session, then all you have to do is close the window. If your resolution is normal, you can also run the HyperV Virtual Machine in full-screen mode, enhancing the display.

Kindly refer to these related guides: How to Resolve Microsoft RDP Connection Black Screen, Enable Remote Desktop Connection on Windows 11 for non-administrators or selected users, How to change the default screen capture format in macOS, You can not open this application because it is in the bin, How to setup external displays on your Mac and arrange your display in Mac and How to fix VirtualBox Displaying only 32 bits Option: Windows Virtualization.

Solution: The control sequence to exit Full Screen mode is CTRL + ALT + PAUSE (Changes the Virtual Machine Connection window to / from full screen mode when using hyperV in full screen mode inside a remote desktop session. 
- Upon pressing all three keys CTRL + ALT + PAUSE, (which need to be held down simultaneously), a normal window bar will appear at the top of the RDP session. You can then use this bar to close or resize the window.

Alternatively, you may want to set the layout (resolution) of the VM using the steps below. In this way, you can also increase the screen resolution of a VM that is already too small in Hyper V. – Most times the CTRL + ALT + PAUSE does not work effectively and you will have to follow the steps discussed below.

Right-click on the Windows desktop and select Display Settings.

Display settings

Under Display, Scale, and Layout as shown below, select a resolution from the drop-down menu that fits your need.

Select a resolution that fits your needs

When this is done, you will get a prompt requesting you to keep the changes or to Revert.

Select keep changes

As you can see below, the VM display is no longer occupying the Hyper Server itself.
