After the Hyper-V graphics card goes through, my discrete graphics card is not displayed, but the virtual graphics card program is displayed.

Question

As shown in the figure, I connected my Hyper-V with the discrete graphics card of my host, but it was not displayed as my discrete graphics card: RTX 2060 in the virtual machine, but as Microsoft Virtual Render Driver。

Excuse me, what is the situation?

Hi Liu Christ,

Thank you for posting in the Q&A Forums.

This is usually due to Hyper-V's graphics card virtualization mechanism. The following is a detailed explanation of this phenomenon:

In a Hyper-V environment, discrete graphics cards are not directly recognized and used by virtual machines as physical hardware. Instead, Hyper-V virtualizes the graphics card through a technology called GPU Pass-through or vGPU. This technology allows a virtual machine to access and use the host computer's graphics resources, but usually not in the form of a physical graphics card.

In a virtual machine, Hyper-V uses the Microsoft Virtual Renderer Driver to emulate and manage graphics card resources. This driver is specifically designed by Hyper-V to provide graphics display and rendering capabilities in a virtual machine environment. Although it does not represent a direct mapping of the physical graphics card, it ensures that the virtual machine is able to display the graphical interface and perform basic graphics processing tasks.

Best regards
