Mac Os X Change Brightness For Given Monitor

Posted on  by

I have my external monitor in spanning mode, not mirror mode. The control window for displays shows a slider on it for the PB and this readily adjusts the brightness of the PB screen. But whether I access the displays controls for the Cinema display with the PB closed or open, there is not slider on the control window for th Cinema display. Oct 08, 2019  In order to change the brightness with ExternalDisplayBrightness, you will need to hold down the Fn key on your keyboard and then tap the function key you set in the app’s preferences. To quit the app, open Activity Monitor and look for it there. To change the keys that you’ve set, run the app again. Oct 08, 2016  Click on the 'Automatically adjust brightness' option to. Your Mac will no longer adjust the screen brightness on its own. In an automatic state. MacOS and OS X.

An on-screen menu appears, with F14 to darken and F15 to lighten brightness. Cool!

sorry but... where are the f14 and f15 keys? i'm usin a ms keyboard

I have the keyboard that came with my G4 400, and there's nothing beyond F12... what kinda keyboard is this?
Is this the old kind that had the arrow keys and pg-up pg-down etc in between alphabet keys and numeric keys? I can't quite picture a newer apple keyboard that's large enough to have F1-F15... but I don't go around looking at keyboards, so I don't really know...
anyway... I thought you could assign whatever to F keys? can't you just make 2 of them to do this?

I just found this works on my iMac G4 by accident and came here to see if this
has been reported on.
Strangely enough I have had my iMac since they first came out and just noticed that it had F13, F14, and F15 above the help, home, and page up keys. I pressed to see what they would do and found the Screen brightness settings. Pretty cool, but mostly useless on the iMac.. I leave it all the way up all the time.
