Hello,
First of all, sorry for my English...
I am looking for help about my problem and after many searches on internet I haven't found a solution.
Since 2 month I have a Mac mini M2 Pro that is connected to a LG Ultrafine 23.7" 4K. My keyboard is a Logi MX Keys for Mac. Everything was working perfectly until three weeks. Indeed, for 3 weeks now and for no reason the F1 and F2 keys on my keyboard that control the screen brightness no longer work.
I can still control the brightness from the control center or the settings.
With the app Logi Options+ I can set up the F1 and F2 keys to other actions (adjust the volume for example, or launch Mission Control) and it works. So the keys aren't defective. Moreover, if I connect my keyboard to my iPad, the F1 and F2 keys can control the brightness of my iPad.
I reset my keyboard, reinstalled the Logi Options+ app, restarted my Mac, my LG... Nothing happens.
I tried with another keyboard, and the brightness keys don't work either.
Very strange thing, if I hold the Control+F1 or Control+F2 keys, it works! I can control the brightness of my LG! I don't understand what's going on. According to my research, the Control+F1/F2 combination allows to control a secondary monitor (for example, a monitor connected to a MacBook). But for my part, I use a Mac mini, and I don't have a secondary monitor...
Would anyone have a solution to this problem? It's frustrating, I don't understand what's going on...
Thank you very much!
