Most users of my Lunar app (https://lunar.fyi https://lunar.fyi) that were coming from Windows, have been praising the Windows multi monitor experience while the Mac felt limited in the handling of external monitors. I admit that finding a way to change monitor brightness [1] or turn off individual displays [2] wasn’t as straightforward and needed a lot of reverse engineering. But macOS has a much nicer API [3] for configuring screen position, resolution, mirroring etc. It’s not without its quirks however, I ran into a lot of bugs while developing the Blackout feature when having to create multiple mirror sets with multiple displays in each one. I finally had to reverse engineer the MonitorPanel.framework that’s used by System Preferences to get that functionality. [4] From my understanding, Windows has a native way of disabling a display in software so this wouldn’t even be needed there.
