MonitorControl is an app to control the brightness and volume of your external display like it was a native Apple display (via the native Apple keys showing the native OSD). The new 4.0.0 version was recently released and has a huge amount of new features compared to previous versions (even though v3.x.x was alerady a feature packed release). App development was supercharged recently - if you did not try MonitorControl or you last tried version 2 or 3 (the latter was released this September), check it out! Some new stuff among other things: - Complete overhaul of the menu UI with Big Sur/Monterey Control Center style sliders. - New combined hw-sw brightness algorithm that is closer then ever to the Apple native feeling. - Smooth brightness transitions. - A lot of customization options and tweakable DDC settings for advanced users. - Fully supports virtual displays (DisplayLink, Sidecar etc) and non-hardware dimming. - Custom keyboard shortcuts (+ of course native Apple keys) - Brightness syncing from the built-in display - Compatibility with BetterDummy https://github.com/waydabber/BetterDummy https://github.com/waydabber/BetterDummy + all the improvements of v3 (Apple Silicon support etc). The app is free and open source. :)
