Here’s the problem: you can’t dim the brightness on an external Apple monitor without connecting it via USB. Who came up with that… This post originally started as a cry from the heart “it’s impossible to change the brightness at all”. Turns out it’s possible, but via USB.
I have two monitors connected to my Macbook Pro, with the MacBook itself closed. One of the monitors – a normal ASUS, connected via HDMI. The other – Mac Display, connected through Thunderbolt.
I suspect that having spotlights on my face for 10 hours a day is the reason for eye fatigue.
A temporary fix was found with an external app “Brightness Slider”. Apple – idiots. Removing the brightness control from the monitor…
P.S. Connected via USB – everything works. But this nonsense takes up an entire port for brightness adjustment (and there are only two). Luckily, the brightness setting doesn’t reset when disconnected. Seems so.
