I'm using a Mac mini M2 connected to a Samsung monitor. The night shift slider is stuck on the left side, essentially making it useless. When I move the slider and click "done", the slider defaults back to the left side. I tried restarting my Mac, updating to the latest OS, and even scheduling/unscheduling Night Shift. The problem started on macOS Sonoma, and continued after updating to Sequoia. Any suggestions?

Thanks for confirming that Night Shift does not work for TV's and Projectors.
I have dual Samsung displays connected my 2018 Mac mini.
The wife has dual LG displays connected to her 2020 M1 Mac mini.
We can both turn on and adjust the slider for Night Shift and it works for both displays.
However, neither of us care for or use Night Shift.
It clearly shows that message in your screenshot.
What cable connection are you using between the M2 Mac mini and the Samsung Odyssey G9...?
(HDMI to HDMI or USB-C to USB-C or USB-C to DisplayPort)
An HDMI to HDMI connection and/or certain Samsung settings, could be tricking the Mac mini into thinking that the G9 is a TV instead of a display.
What Samsung monitor do you have and how is it connected to the Mac mini...?
You can not Turn on Night Shift or adjust the Slider, because the system thinks the Samsung is a TV or Projector.
Sorry, I see that you have already tried what I suggested.
I did not know that, however when I select my attached TV I can move the slider but it only alters colours on my normal monitor.
I have a Samsung Odyssey G9. I do not see that message saying Night Shift isn’t available. In fact, Night Shift was working last month
MacOS Night Shift slider is stuck on the very left (it's basically OFF)
