Where did you find that out? I'm reading this through my perfectly dimmed external screen running macOS Catalina.

  I found it out by plugging in an external monitor and Night Shift not working with it. I could believe it is specific to the monitor you have, but judging by Apple support I'm not alone: https://discussions.apple.com/thread/251249337 https://discussions.apple.com/thread/251249337 The answer implies that it only works on about four different monitors. I doubt that's true but it seems like a shot in the dark to know which it does and does not work with. EDIT: just tried it again with Catalina. Nope.

    I have a (probably) related issue on my dual display system where it works on one but not the other, making it just as useless in practice. I still use f.lux as a result.

    Interesting, never heard of that before! I use a 5 year old Dell P2715Q screen and I just enabled / disabled it and it's working fine so that list of screens seems to be outdated.

      Works fine on a Dell and an Acer for me, never heard of that before as well.
