I used an app to register the fn key to other key and finally I could use the F1 and F2 alternate function, but I can't change the brightness. The F1 key changes the triple monitor configuration, mirror or three different desktops, and the F2 does nothing. I needed to figure out if I could change the brightness with other app, so I downloaded this app https://www.tonymacx86.com/threads/controlling-your-monitor-with-osx-ddc-panel.90077/ and in fact it did change the brightness! What do you think the problem is? Key assignment or maybe the triple monitor setup?I think I didn't do any configuration or used any app that could mess with the keys. By default the keyboard is using Function keys primarily (F1, F2 etc). Only if I press Fn the other functions will be enabled (Mission Control, Volume etc). But I'll try later registering F1/F2 to other keys, as you mentioned.
I confirmed in the LG site that these monitors have DDC/CI. I'll also check in the monitor option menus if there is any option to enable/disable this.
By the way in DCC Panel (the working app) I need to select each screen at a time in order to change the brightness. It would be great if your app changed all the three at the same time.
