How to Set Up a Virtual Display Manager for Dual Monitors

Virtual Display Manager (VDM) is a software category and specific utility designed to supplement single or multi-monitor systems by creating, managing, or subdividing screens into virtual displays. Depending on the context, it usually refers to either an ultrawide monitor management software, an AR/VR headset companion app, or a software-emulated virtual monitor driver. 1. iShadow Virtual Display Manager

This is the most common commercial application named iShadow Virtual Display Manager. It is highly popular among users with massive ultrawide monitors who want to split up their screens more effectively than standard window-snapping tools like Microsoft PowerToys.

True Virtual Partitioning: Unlike window-snapping software, it splits a single large monitor into distinct virtual displays that behave like native physical monitors.

Full-Screen Optimization: If you maximize an application or trigger a full-screen YouTube video, it will fill only that specific virtual display partition instead of the entire physical screen.

Enterprise Features: It supports Virtual Desktop Infrastructure (VDI) environments, remote desktop session syncing, and preservation of desktop icon positioning. 2. Hardware-Specific Hardware Managers (Lenovo & ViewSonic)

Major hardware manufacturers bundle proprietary software under this name to control their unique displays or smart glasses:

Lenovo Virtual Display Manager: Built as a companion application for products like the ThinkReality A3 smart glasses. It projects up to five virtual desktop screens directly into the user’s augmented reality space.

ViewSonic vDisplay Manager: An intuitive desktop tool designed for select ViewSonic monitors. It replaces tactile monitor buttons by allowing you to control brightness, contrast, screen partitioning, and input sources directly via your OS. 3. Open-Source Virtual Display Drivers

If your goal is to trick your PC into creating a completely invisible secondary screen rather than partitioning an existing one, you might be looking for a Virtual Display Driver (often managed via Windows Device Manager). How to use the Virtual Display Driver with Sunshine!
