Adjust Brightness on LG 34um69g-B Ultrawide Monitor from a keyboard connect to Mac Book Pro 15" Mid 2015
I recently purchased LG 34um69g-B. My Laptop is a MacBook Pro (Retina, 15-inch, Mid 2015). Everyone is working fine, except that I can't adjust the monitor brightness via the keyboard. I have to do it via OnScreen Control program. Does anyone know how this can be made to work?
thanks,
