I'm running a 3 screen setup currently. 2 nice matte Samsungs that I do all my work on and one glossy Apple screen that has the camera and microphone on it. I want to continue to use the camera and microphone on the Apple screen for my video conferences, but I don't want video to go to it any more/have apps see it as a valid screen and pop up on it. So, ideally I just disable it in the display control panel, but I don't see any options to do so.
Ran across a GitHub project that claims to do so, but when I tell it to power off one monitor they ALL power down, so that's not going to work... Any other ideas? Even if it's a shell script I have to run on each boot I'm fine with that. I basically never want video to go to that monitor so I don't need a fancy UI.
