The pre-command version of this script is more "reactive", meaning it only runs when necessary. It also has a longer grace peroid during the suspension of a stream, 120 seconds, before reverting back. When ending a stream in Moonlight, it will revert back instantly.

Requirements:

• Host must be Windows
• HDR Capable Display
• Sunshine 0.21.0 or higher

Caveats:

• If using Windows 11, you'll need to set the default terminal to Windows Console Host as there is currently a bug in Windows Terminal that prevents hidden consoles from working properly.
  • That can be changed at Settings > Privacy & security > Security > For developers > Terminal [Let Windows decide] >> (change to) >> Terminal [Windows Console Host]
• Due to Windows API restrictions, this script does not work on cold reboots (hard crashes or shutdowns of your computer).
  • Fortunately recent changes to Sunshine makes this issue much easier to workaround.
  • Simply sign into the computer using the "Desktop" app on Moonlight, then end the stream, then start it again to resolve issue in this scenario.
• The script will stop working if you move the folder, simply reinstall it to resolve that issue.

What it Does:

Checks to see if the last connected Moonlight client asked for HDR, if so, it will enable HDR. Otherwise, it will disable it. Once the stream ends, it will configure the last HDR setting prior to starting the stream.

Credits:

The HDR toggling code is from the following repositories:

• https://github.com/Codectory/AutoActions - The original developer of the HDR toggle code that made calling the DLL possible.
• https://github.com/anaisbetts/AutoActions - She added two additional exported functions to make calling the DLL easier.
