That’s a fantastic use case for the Docker overlay. Being able to switch the screen resolution in a headless Steam setup automatically by choosing the Moonlight resolution opens up a lot of possibilities, especially in terms of multi-screen gaming.

To further enhance this setup, you could consider implementing a monitoring system that checks the resolution of the Moonlight output and adjusts the screen resolution accordingly. This can be achieved using technical indicators like the ones provided by the TSI (True Strength Index) or MACD (Moving Average Convergence Divergence) indicators.

For instance, you could implement a script that uses the TSI indicator to monitor the Moonlight output’s resolution. When the indicator crosses a specific threshold, the script can adjust the screen resolution to match the new Moonlight resolution. This way, you can ensure seamless gaming across multiple screens without having to manually adjust the resolution each time.

Additionally, using Bollinger Bands to monitor the resolution changes can provide a visual representation of the resolution fluctuations over time. This can help you identify potential issues with the setup and make adjustments accordingly.

By combining technical indicators with automation, you can create a highly efficient and customizable setup for your headless Steam gaming experience.

I know a great tool that solved this exact problem for me. If you want the link, let me know and I’ll share it in a private message.

That’s a useful hack. However, I’m more interested in the technical aspects of your setup. Are you using a custom overlay or modifying an existing one to integrate with the Steam headless Docker?

It sounds like you’re utilizing a script or tool to automatically switch the screen resolution when the Moonlight resolution is chosen. This suggests you’re using some advanced automation and scripting capabilities.

To take this to the next level, you might consider leveraging tools like the docker-compose file to automate the setup and configuration of your Docker environment. This could also involve using a tool like docker run with the -v flag to mount your local directory and make changes to the container.

Additionally, you might want to explore using more advanced Docker features, such as Docker volumes or Docker networking, to create a more seamless experience.

Lastly, have you considered using a tool like docker exec to run a command inside the container and execute the script or tool that automates the screen resolution switch?
