To stop your screen from auto-dimming, particularly if it's related to system or app-controlled lighting adjustments, you can adjust settings in the Dynamic lighting section of your system's personalization options.
Understanding Auto-Dimming
Screen auto-dimming can occur for several reasons, including power saving, ambient light sensor input, or software features designed to adjust brightness based on content or application activity. The provided reference points to a specific setting within Windows, known as "Dynamic lighting," which can control how apps and devices manage lighting, potentially including screen brightness in some contexts or related lighting effects that might affect perceived brightness.
Adjusting Dynamic Lighting Settings
Based on the reference, a key step to prevent auto-dimming potentially linked to applications or system-controlled lighting is to disable specific options within the Dynamic lighting settings.
Here are the steps:
- Navigate to your system's Settings.
- Select Personalization.
- Find and click on Dynamic lighting.
- Locate the options and disable the following:
- Use Dynamic Lighting on my devices
- Compatible apps in the foreground always control lighting
Disabling these settings, especially "Compatible apps in the foreground always control lighting," can prevent software applications from overriding your manual brightness settings or initiating automatic adjustments, which might manifest as auto-dimming.
Settings Summary Table
Here's a quick overview of the settings to change according to the reference:
| Setting Category | Specific Setting | Action |
|---|---|---|
| Personalization | Dynamic lighting > Use Dynamic Lighting on my devices | Disable |
| Dynamic lighting | Compatible apps in the foreground always control lighting | Disable |
By turning off "Use Dynamic Lighting on my devices," you prevent the system from using this feature altogether. Disabling "Compatible apps in the foreground always control lighting" specifically stops applications from taking control of lighting features, which the reference suggests can be a cause of unwanted adjustments like auto-dimming.
Remember that other settings, like power plan options (which might dim the screen after inactivity) or adaptive brightness controlled by ambient light sensors, can also cause auto-dimming. If adjusting Dynamic Lighting doesn't resolve the issue, you may need to check those settings as well.
