If the entire room glows a bright white whenever you use your computer, you may need to know how to adjust the brightness on your Mac. The screen adjustments are within the Mac OS X system itself, rather than on the monitor. A MacBook, as well as an Apple keyboard, have keys allowing adjustment, but if you’re not using either, this is a quick and easy fix.
- Click on the Apple in the top left corner of your screen and click on “System Preferences.” You will be able to access the menu this way, but you can always search for “System Preferences” in your Spotlight (the magnifying glass in the right top corner).
- Under the heading of “Hardware,” select “Displays.” This will give you access to many of the adjustment settings for your monitor, including resolution.
- Using the slider labeled “Brightness,” adjust the level to the left or right. Your monitor will show the changes immediately as you move the slider for a perfect adjustment the first time.
- Click on the red button with an “X” in the top left hand corner of the Display window. Your changes are saved immediately.
Tip: It is best to keep the brightness of your Mac display at a moderate level. If the monitor is either too bright or too dim, it can cause eyestrain.
Warning: Avoid adjusting any additional display settings unless you are certain of the changes. Incorrect color or resolution changes can result in the display being difficult or impossible to read.
