Many of our readers complain about the screen being dark despite enabling full brightness. It’s usually because of the adaptive brightness settings or an outdated display driver. Here are our tested solutions to fix this problem.
How do I fix a screen that is too dark at full brightness?
1. Disable adaptive brightness
- Press the Windows key + I to open the Settings app and select the System option.
- Choose the Display option in the left pane.
- Now, uncheck the box next to Change brightness automatically when lighting changes under the Brightness and color section.
Adaptive brightness automatically adjusts the brightness level of your screen based on ambient light sensors. When enabled, it will change your screen’s brightness even though you set it to 100%.
2. Enable high performance mode
- Hit Start, type Control Panel, and open it.
- Select Power Options.
- Set it to High Performance.
This option prioritizes performance over battery saving and won’t dim your light.
3. Run the Power troubleshooter
- Press the Windows key + I and select the Update & Security option.
- Choose Troubleshoot in the left pane and click the Additional troubleshooter’s option.
- Select Power and click the Run the troubleshooter button.
Minor issues with your PC power setting can affect your screen brightness, causing your screen to become so dark. In this case, you need to run the Power troubleshooter.
