Common Mistakes

• Not checking system updates, which can fix bugs related to display controls.

• Adjust brightness in low-light environments to reduce eye strain.
• Consider setting different brightness levels for battery and plugged-in modes for optimal power saving.

Troubleshooting

If you’re unable to change your screen brightness in Windows 10, follow these troubleshooting steps:

1. Check for Windows Updates:

   Go to Settings > Update & Security > Windows Update and click Check for updates. Installing the latest updates can resolve bugs affecting display controls.

2. Update or Reinstall Display Drivers:

   Visit your device manufacturer’s website or use Device Manager to update your display drivers. If updates don’t work, uninstall the driver and restart your PC to allow Windows to reinstall it automatically.

3. Verify Hardware Compatibility:

   Ensure your display hardware supports brightness adjustments. External monitors may require specific drivers or on-screen controls.

4. Use Troubleshooter:

   Navigate to Settings > Update & Security > Troubleshoot > Additional troubleshooters, then run the Hardware and Devices troubleshooter.

5. Reset Power Settings:

   Sometimes, power settings interfere with brightness controls. Reset them by going to Control Panel > Power Options, selecting your plan, and clicking Restore default settings for this plan.

6. Check for External Factors:

   If you’re using an external monitor, adjust brightness directly on the monitor or via its settings menu.
