Thank you for your work. I installed the application on my Surface Pro 4. When you press the keys, the brightness animation works, but nothing happens. I have doubts if my machine is compatible. Know you?

There are apps that control brightness of monitors that do not support DDC/CI, like Acer AG241QG.
Particularly http://www.charcoaldesign.co.uk/shades or https://itunes.apple.com/ru/app/brightness-slider/id456624497?mt=12
but their interface is horrible.
Yet your app interface works on mine AG241QG. It would be really nice to combine software brightness adjustment and MacOS brightness keys/indicator integration.
Any hope you can do that?

Hello,

I have 3 Asus VX229H monitors connected to a GTX1080 via DP to HDMI adapters. Using this application, the brightness for the first monitor (the one that displays the apple logo when booting) can be changed, however the other two remain unaffected. Is there anyway to make this program function with multiple displays? Preferably changing the brightness on all of them to the same value at the same time?

Thanks!

[1] - I HAD DECREASED THE BRIGHTNESS OF MY SAMSUNG M5 MONITOR TO THE LOWEST, BY REMOTE OF THE MONITOR THROUGH ITS INBUILT PICTURE SETTINGS .
[2] - AND THE MONITOR DOEST NOT SUPPORT DDC/CI SO I CANNOT CONTROL ITS BRIGHTNESS THROUGH ANY APP OR SOFTWARE.
[3] - I HAVE TO WORK ON WHITE SCREEN FOR 7 TO 8 HOURS SO IT GIVE SO MUCH STRAIN ON MY EYES .

IF ANY SOLUTION AVAILABLE PLEASE SHARE IT WILL BE GREAT HELP

Dear developer,

I'm using this app since quite a while, and it worked perfectly on my 2018 MacBook Pro with a HP z32 display.

Now I'm changing to a new MacBook Pro M3 Max and was wondering, if your app supports this system? The app is installed through my backup, and when I'm pressing the keys to change the brightness, I'm seeing the brightness control on my HP screen, but the actual brightness is not changing.

Do you have by any chance a solution for that?

Thank you so much in advance für your help and best wishes, Carsten

currently, after restarting my mac, brightness bar will be reset to 50%, but the brightness itself will be remembered, if I click F1 the brightness bar show me the 50%.

e.g. before I shutdown my mac I have 30% brightness, and after restart everything looks fine, unless I click F1 or F2 again, the brightness will be set to 50%.and I need to adjust brightness from 50% which is annoying

Brightness buttons works only with Fn button and if I check "Use all F1, F2, etc keys as standart function keys", Brightness buttons works great, but another function keys (F3-F12) do not work as multimedia butons. I think function "Use all F1, F2..." should not affect Brightness buttons at all to work them without Fn key.

P.S. Using beta version 12.1.5 on Apple Magic Keyboard 1 and hope you will hear me and correct it.

Hello! I am trying to compile for 10.9.5 and get three errors:
CFMachPortRef eventTap = CGEventTapCreate(kCGAnnotatedSessionEventTap, kCGHeadInsertEventTap,
kCGEventTapOptionDefault, interestedEvents, keyboardCGEventCallback, (__bridge void * _Nullable)(self)); // ) Expected

and
[NSEvent addGlobalMonitorForEventsMatchingMask:NSEventMaskKeyDown | NSEventMaskKeyUp
// Undeclared
please help

the 0.0.5 release claims to be version 1.0.0

version numbers on github should match up with the version numbers in the app ( CFBundleShortVersionString & CFBundleVersion )

can not open in macOS Mojave latest version 10.14 Beta (18A336e).

I was pointed to this app (actually a fork of it) to control the internal MacBook display using the internal GPU. I have disabled the discrete GPU because it is fried and then brightness is not controllable anymore, a known issue.

Should it work? It does not, I get the brightness animation up when using F1 and F2 functions, but nothing happens.

work perfectly.
thanks a lot !!!

NativeDisplayBrightness is causing a hang on shutdown in El Capitan for me. Sierra as well, but hang not as prominent. Quitting the application does not work, but force quitting quitting the application before shutdown alleviates the problem. Console tells me that there is a delay between caught SIGTERM and being forced to quit to reboot. Version .2 did not have these issues.

Thank you Very much !

Developer, Thanks you very much!

After upgrade to Catalina NativeDisplayBrightness stopped working. The process starts but there is no menu and the brightness keys don't react. New installation and updating the security settings brought no change. Will there be Catalina support?

Would be great to can change brightness +- 5 increments.

Is it possible to make it also work on Apple keyboard where F1/F2 are brightness dim.
I found no matching kVK key code for these two keys tho.
