🔆How to Fix Screen Brightness Changes Automatically🔆
Have you ever experienced your screen brightness constantly changing on its own? It can be quite annoying and disruptive, especially when you're trying to focus on a task or enjoy watching a video. In this article, we will explore various methods to fix this issue and put an end to the automatic screen brightness changes. We will delve into the causes of this problem and provide step-by-step solutions to resolve it. So, let's dive in and regain control over your screen brightness.
1. Introduction
The screen brightness of your computer is an essential aspect of your viewing experience. However, when it starts changing automatically, it can be frustrating. In this article, we will discuss the causes of screen brightness changes and provide practical solutions to fix the issue.
2. Causes of Screen Brightness Changes
2.1 HDR (High Dynamic Range) Setting
One possible cause of screen brightness changes is the HDR (High Dynamic Range) setting. HDR dynamically adjusts the contrast of your monitor screen based on the content being displayed. While it may enhance certain visuals, it can also lead to unwanted brightness fluctuations. Disabling HDR can help stabilize the screen brightness.
2.2 Adaptive Brightness Setting
The adaptive brightness setting, available on laptops, also contributes to automatic screen brightness changes. This feature adjusts the brightness based on ambient lighting conditions. However, it's not always accurate and can cause inconveniences. Turning off the adaptive brightness setting can prevent unwanted adjustments.
2.3 Desktop Power Settings
For desktop computers, power settings play a role in screen brightness changes. Within the power settings, you can find options to adjust the display brightness. Some settings, particularly those related to power saving mode, can dim the screen to conserve energy. Changing these settings can help maintain a consistent screen brightness.
2.4 Laptop Power Settings
Similar to desktops, laptops also have power settings that affect screen brightness. The power-saving mode often triggers screen dimming to extend battery life. By tweaking the power settings and disabling the dimmer display brightness option, you can avoid unnecessary changes in screen brightness.
2.5 Group Policy Editor
Windows 10 Pro and above users can utilize the Group Policy Editor to address the screen brightness issue. Accessing the editor and navigating to the system's power management settings allows users to tailor video and display settings. By adjusting the options such as "reduce display brightness on battery" and "reduce display brightness plugged in," users can set their preferred brightness levels.
2.6 Registry Settings
Advanced users can opt to adjust registry settings to control screen brightness. The registry provides a percentage setting that determines the desired brightness level for the monitor. This method gives users precise control over their screen brightness.
3. Fixing Screen Brightness Changes
Now that we understand the potential causes of screen brightness changes, let's proceed with the step-by-step solutions to fix the issue.
3.1 Disabling HDR Setting
To address the dynamic contrast caused by the HDR setting, follow these steps:
- Go to your monitor settings by accessing the back panel of the monitor.
- Locate the HDR option and ensure it is turned off.
Disabling HDR prevents automatic dimming and brightening of the screen, providing a more stable brightness experience.
3.2 Turning off Adaptive Brightness
For laptops, the adaptive brightness setting can be turned off using the power settings. Here's how to do it:
- Search for "power settings" in the search bar and open it.
- Access the "advanced power options" and navigate to the display brightness settings.
- Disable the "enable adaptive brightness" option.
Disabling adaptive brightness ensures that your screen brightness remains constant regardless of lighting conditions.
3.3 Adjusting Power Settings
Customizing power settings can help prevent screen brightness changes. Users can modify the power management settings to suit their preferences. By specifying the display dim brightness on battery and plugged in, users can maintain a desired brightness level. Experiment with different percentage values to find the optimal setting for your needs.
3.4 Updating Group Policies
If you have Windows 10 Pro or above, utilize the Group Policy Editor to adjust video and display settings. Here's how:
- Open the Group Policy Editor by typing "gpedit.msc" in the search bar.
- Navigate to "Computer Configuration" and access "Administrative Templates."
- Select "System" and locate "Power Management" settings.
- Click on "Video and Display Settings" to customize the options according to your preferences.
Updating group policies ensures that the desired brightness settings are enforced consistently.
3.5 Choosing Power Plan
In addition to adjusting power settings, selecting the appropriate power plan can impact screen brightness changes. Windows offers different power plans such as power saver, balanced, and high performance. Choosing the high performance plan on laptops provides a consistently bright screen, albeit at the expense of reduced battery life.
4. Conclusion
Automatic screen brightness changes can be frustrating but rest assured, there are solutions available. By addressing HDR and adaptive brightness settings, modifying power configurations, and leveraging advanced options like Group Policy Editor and registry settings, users can regain control over their screen brightness. Experiment with different settings and find the ideal configuration that suits your preferences. Enjoy a seamless viewing experience without the distraction of fluctuating screen brightness.
