DisplayMagician

DisplayMagician is a nifty tool designed to help you customize the display and sound for any game or application installed on your computer. The tool was created for simracers in particular, as these apps usually need some extras to give additional functionality to the game. However, it works with all other games and apps.

The app automatically launches games and apps with your configuration

The application comes with a rather rugged, but user-friendly interface that is quite easy to navigate. As prompted within the interface, you can get started by creating a profile and begin the configuration from here. To put it simply, you can select the audio output, which can be more than one for a single game, so you can include your special hardware in the mix.
The tool enables you to add one or more start programs before the app or game, pass arguments to the program or simply make sure a program shuts down when you are launching a game. You can create shortcuts so that you launch the games with just one click and with the desired configuration. As you probably hinted, you can decide what happens to the display and audio once you close that game or app.
On a side note, for the time being the app supports NVIDIA surround setups, but does not work with AMD Eyefinity. The latter support is planned to be included in the future.

Works with several game launchers and supports game shortcuts

According to the developer, the application is compatible with several game launchers, namely Steam, Galaxy of Games, Origin, Epic Games and Ubisoft Uplay. You can create a shortcut that changes to a different display profile when one of the aforementioned is launched or make individual shortcuts for various games you accessed via these launchers.
In the eventuality that you would like to create specific display and sound configurations for the games you're playing or apps used regularly, then perhaps you can consider giving DisplayMagician a try.
