How do I lower the birghtness on an acer display connected to my macbook air?

I can change the brightness on my laptop, but it won't reflect on my monitor. When I go into display settings for the monitor, the display brightness is blocked off. I also don't have access to lower the brightness on the monitor's keyboard.

MacBook Air 13″, macOS 11.0

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!

Studio display brightness can't be adjusted from control center Hello, I use my Studio Display with a MacBook Pro 13-inch, 2020 (Intel i5), macOS Ventura 13.0.1. When I try to adjust the display brightness manually, sometimes it is possible to do so from the control center, but sometimes the brightness control is grayed out and disabled. The display does respond to brightness adjustments, but only from the "Displays" menu on System Settings. Does anyone know a fix for that?

Can't adjust brightness on external monitor - Mac Studio w/Ventura I just bought a Mac Studio and new monitor. I have a Viewsonic monitor connected to a M1 Max Mac Studio (Running Ventura). I am unable to adjust the brightness using the F1/F2 keys (with or without the Fn key pressed) I am unable to control brightness from the control center (greyed out) Under Displays in system settings, there is no option to change brightness. Changing the picture profile did nothing, there is no HDR button to deselect (As suggested by others). It seems that everyone shows a screenshot with some different display controls... I will attach what I see in my setup. Any ideas on what to do?? It's almost as if the brightness is full blast, the whites are blinding!
