Change Screen Resolution of An Ubuntu VM in Hyper-V

Virtualization technology is essential in today’s IT landscape, allowing users to run multiple operating systems on a single physical host. Hyper-V is a powerful virtualization platform developed by Microsoft, widely used for running virtual machines (VMs) on Windows Server systems. When working with an Ubuntu VM in Hyper-V, one common challenge that users face is the need to adjust the screen resolution for a better user experience. The default screen resolution may not be suitable for your display, making it difficult to work efficiently.

In this article, we will provide a step-by-step guide on how to modify the screen resolution for an Ubuntu VM in Hyper-V, ensuring optimal usability and an enhanced visual experience.
