Why does my Mac automatically adjust brightness?
Macs with built-in ambient light sensors can monitor the light level nearby and automatically adjust the display’s brightness level to be suitable. This means making the display brighter when it’s bright near you, and making the screen dimmer when you’re in the dark.
Why is my 2nd monitor brighter?
If you use different ports (DVI, VGA, HDMI) to connect your dual monitors, you may get high or low color depth and different brightness levels. Stop using the VGA port to fix this. Instead, use either DVI or HDMI port to connect both monitors and see if you notice any improvement.
Can a monitor be too bright?
If it looks like a light source in the room, it’s too bright. If it seems dull and gray, it’s probably too dark. If you work in a shiny reflective office, applying a glare reduction filter to your screen can also provide relief. Most monitors let you adjust the color temperature manually.
How do I raise the brightness on my Mac?
If you have keyboard controls that raise and lower the monitor brightness of any of yourscreens, you can raise and lower the brightness of the second or third screen simply by making a program’s window active on the desired screen and pressing the brightness keys. This works on my MacOS 10.13.
Is there a way to change the brightness of an external display?
External displays have their own set of keys for controlling brightness and contrast. The brightness keys on the keyboard cannot change the brightness of an external display regardless if you’re on a Mac or a Windows 10 PC. That said, you can use an app and control brightness for external displays with your keyboard.

Why does my Apple Monitor need to be plugged in?
Some Apple displays that have a USB pigtail require that the USB be plugged into the computer (even if you don’t use the USB hub in the display) because they talk to the display across USB to adjust the Brightness. I use a slightly older 30-in cinema display, and if you get the USB unplugged, the slider does nothing.
