How to Adjust External Monitor Brightness on Windows and Mac

Any kind of Mac, including the MacBook and Windows, can be used in conjunction with an external or additional monitor. You are not required to use an Apple-manufactured or -approved display; however, those will function the most effectively. If you have a display that is not Apple-approved, you will discover that it is still functional; however, it will not perform as well as an internal display would. In this article we will discuss about the how to Adjust External Monitor Brightness on Windows and Mac.

When used as a secondary display, a smaller number of its features will be operational. One good example is the level of brightness. Users are able to adjust the brightness of their displays, which is a fundamental setting. Some people modify it depending on the time of day or the amount of light that is present in the room.

On an Apple keyboard, there are buttons specifically designated for adjusting the level of brightness; however, these buttons are ineffective on displays connected to other devices. Here is how to control the brightness of external monitors on macOS, as well as how to configure the dedicated brightness keys on an Apple keyboard to change the brightness of all connected displays at the same time.

Why Adjusting Monitor Brightness is Important

• Eye health: Staring at a bright monitor for extended periods of time can cause eye strain, fatigue, and other eye problems. Adjusting the monitor brightness to a comfortable level can help to reduce eye strain and protect your eyes.
• Image quality: The brightness of the monitor can affect the image quality. A monitor that is too bright can make it difficult to see the details of the image, while a monitor that is too dark can make it difficult to see the image at all. Adjusting the monitor brightness to an appropriate level can help to improve the image quality.
• Comfort: The brightness of the monitor can also affect your comfort level. A monitor that is too bright can be uncomfortable to look at, while a monitor that is too dark can make it difficult to see what you are doing. Adjusting the monitor brightness to a comfortable level can help to improve your comfort level when using the computer.

Tips for Optimal Monitor Brightness

• Adjust the brightness to match your environment. The brightness of your monitor should be similar to the brightness of the room you are in. If the room is too bright, the monitor will appear too dark. If the room is too dark, the monitor will appear too bright.
• Use a well-lit room. Working in a well-lit room will help to reduce eye strain. Avoid working in dark rooms, as this will make it more difficult to see the screen and can lead to eye strain.
• Use the monitor’s brightness controls. Most monitors have built-in brightness controls. You can use these controls to adjust the brightness of the monitor to a comfortable level.
• Use a third-party brightness adjustment tool. There are a number of third-party brightness adjustment tools available. These tools can be used to fine-tune the brightness of the monitor and to create different brightness profiles for different tasks.
