I can't say for sure if your problem is related to f.lux, there maybe another app on your system affecting the Gamma tables. In my case, when I quit Lunar Lite, the display was still dim because f.lux was persisting the Gamma changes.Īfter also quitting f.lux, the system reverted everything as expected. Because f.lux also uses Gamma for adjusting color temperature, both apps will adjust the Gamma tables at the same time which can lead to the last tables persisting in the running app. One thing I could reproduce was a clash between f.lux and Lunar Lite. I used my M1 MacBook Pro, one LG 4K monitor connected using USB-C, one iPad connected using Sidecar, one LG TV connected using both Airplay and HDMI (not at the same time). I did try to reproduce the issue but couldn't. Only DDC can have that effect because the brightness is persisted in the monitor controller memory.

This is enforced by the macOS system, and even if I wanted to deliberately do it, I wouldn't be able to set the monitor to completely dark after the app is quit. What I was trying to explain is that macOS removes any Gamma table adjustment as soon as you quit the app. Rating has been adjusted accordingly (no change). It would be nice if the developer could at least try to reproduce the issue, maybe ask the user to help with debugging and find out the root cause (either within the app or otherwise), rather than assuming the user was using a different app or running a beta version OS. I didn't expect the app will work after it exits, but I do expect that it doesn't turn the display to blank on exit. I only had one brightness adjustment app installed on this computer (this app). Thanks for the response! While someone coming from the website might incorrectly assume this app uses DDC/CI and your app description doesn't say it is software dimming, this is not the main reason I wrote this review. The app doesn't actually change the monitor's brightness using DDC/CI, it uses some sort of software overlay instead. I had to disconnect, power cycle my monitor to be able to see anything again.Ģ. The monitor will go completely dark after exiting this app.
