DisplayMagician is a free, open-source Windows automation tool designed to manage and switch display layouts, audio devices, and background programs automatically when launching a game or application. Created by developer Terry MacDonald, it is highly popular among PC gamers—especially the sim-racing and flight-simulator communities—who frequently swap between single-desktop monitors, VR setups, or multi-display configurations.
The tool is officially hosted and maintained on the DisplayMagician GitHub Repository. Core Features and Capabilities
Automated Profile Rolling: Changes your layout, resolution, refresh rate, scaling, and HDR settings when an application opens.
Automatic Rollback: Runs silently in the background while you play. Once you close the game, it instantly restores your original desktop and sound settings.
Single-Shortcut Launching: Generates a dedicated Windows desktop shortcut (or hotkey) for a specific game. Clicking it triggers the entire configuration process.
Companion Program Execution: Launches secondary peripheral software (like SimHub, OBS, Discord, or Steam) alongside your game, and forcibly closes them upon exit.
Audio Device Swapping: Switches Windows sound outputs and microphone settings automatically. This is ideal if you only use a gaming headset or VR audio during specific games.
Broad Display Tech Support: Seamlessly manages configurations involving NVIDIA Surround, AMD Eyefinity, and NVIDIA Mosaic multi-display rendering pipelines.
