The already mentioned Lunar also has also the option to turn of hardware control (it will use gamma control then) - it has a cheaper app store version which uses software control only.

You can simply turn off hardware control in Preferences/Displays if you don't want the display hardware itself to change the backlighting level (even though this gives the best visual result) - the app will then use software dimming (changes the output level of the video by altering the gamma tables or alternatively, if you disable that as well, by putting a dim overlay over the screen - both options are selectable in the app). You can check out the free and open source MonitorControl app on GitHub.

Hi macOS you have plenty of options to change the brightness for third party displays both via hardware control and via software control: I've been going round in circles for days looking into this, even thought about just sticking with Linux but I'd really like to get into Mac OS has anyone got any thoughts suggestions. Only thing i think that would work is these apps that put an overlay up to darken the screen, but is this really my only soultion? I've found apps like Lunar that can turn brightness down but again these seem to control the monitor and not the video card so im guessing there is a higher chance of whinning noise with these apps too. The best way to avoid this whinning noise is doing what worked for me on my PC and thats turning the brightnes down via the video card output rather than the monitor but im not sure that is even possible on a mac? I've looked into the imac 24' but i've been put off by a number of reports of the same issue i have with my current monitor, ie whining noise when brighness is low and it seems to be quite a widespread issue.

Im after a new monitor that comes with its own software that i can control the brightness with but its not proving easy to find at all.Īlso a monitor with its own nightmode too, as im guessing apples might not work either? The LG ultrafines 24 and a 27 offer seamless intergration but the 27 is out of my price range and the 24 dosnt seem to be in stock anywhere.īecause i suffer from haeadaches i adjust brightness quite frequently on my PC through Nvidia software, i dont do it through my monitor controls because it produces a very annoying whinning noise when brightness is low and its very slow this way. Im looking at getting a mac mini and a new monitor to go with it.
