Before opening the issue, have you...?

Searched for existing issues

I have a monitor that has multiple inputs. I would like to use MonitorControl to change the input of the secondary monitor. This should be possible with DDC. Code to make this change is in the open source tool ddcctl but it does not seem to work on my OS (Senoma 14.5)

Describe the solution you'd like

I would like to be able to change the input of the secondary monitor with a hotkey or with the menu control (and ideally from the command line, by sending a message to the app).

Describe alternatives you've considered

I tried ddcctl but the version I had was reading the file /Library/Preferences/com.apple.windowserver.plist instead of /Library/Preferences/com.apple.windowserver.displays.plist. When I added a symlink, ddcctl crashed with:

*** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '-[NSTaggedPointerString countByEnumeratingWithState:objects:count:]: unrecognized selector sent to instance 0x90e7add34cacd282'

Anything else?
