Lunar allows you to change the hardware brightness and contrast of the monitor (the one that can be controlled with the hardware buttons on the monitor)

It's hard to strike a balance between simplicity and configurability. Hey thanks for the feedback! I know the UI is a bit too complex at the moment. I have yet to try Lunar but I definitely will much appreciated. But, this is a rant for another day.Īnyway, I built my own very simple utility to poll the internal display for its brightness and write that same brightness to the LG via DDC, but never had the time/energy to make it more robust for publishing to the web. It works well with Night Shift and True Tone (and f.lux if gamma/software controls are not used).Thanks for writing this! When I got an iMac Pro in 2017 with an accompanying LG UltraFine 5K display I was shocked to learn three things: 1) adjusting the brightness on the internal display is easy but on the LG it's a pain in the ass, 2) despite having ambient light sensor hardware the LG does not automatically adjust its brightness like the internal display, and 3) macOS offers no built-in mechanism to sync the brightnesses of these two displays.īefore learning these things I was feeling excited about Apple's re-committing to the Mac around that time, but man these things made it feel like such 'commitment' was just surface level - such low-hanging fruit not being handled is a shame.It doesn't interfere at all with the native adaptive brightness that macOS implements for the built-in display.Manual controls and hotkeys for setting brightness and contrast that respect the min/max values per monitor.App Exception list if you need more brightness for specific activities (watching movies, design work).Location-based Adaptive Brightness (and contrast) based on the sunrise/sunset times in your location.Sync-based Adaptive Brightness (and contrast) based on the built-in light sensor of the Macbook or iMac.Sensor-based Adaptive Brightness (and contrast) based on an external light sensor.Lunar adjusts the brightness in the same way that the monitor's physical buttons do.
