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.
