Brightness adjustment is not available in Display settings - workaround

I have a m2 mac mini with a Dell monitor and I have not been able to adjust my display brightness (I have migraines). The answer I found was connecting my monitor through usb c! HDMI won't let you make adjustments! Now everything works!

iPad, iPadOS 18

That sounds right. HDMI carries no monitor control signal, afaik, so display brightness would have to be made via the monitor's in-built control menu. However, USB can and does carry monitor and system control data, including volume change and brightness dimming.


Good catch. Thank you for sharing. 🙂👍🏽
