screen brightness on windows 10

Hi,

Some computers can let Windows automatically adjust screen brightness based on the current lighting conditions.

To manually adjust the screen brightness, we suggest following these troubleshooting steps:

• Click Start, then select Settings.
• Choose System, then select Display.
• Under Brightness and color, move the Change brightness slider to adjust the brightness.

Feel free to post back if you have other concern.

 

Lock Screen Dims (Brightness Auto Reduce at Lock Screen)

Hi,

Since you're having an issue with the brightness of your Lock Screen, we suggest uninstalling the display adapter from the Device Manager. Just follow the steps below:

• Press Windows key + X.
• Select Device Manager.
• Locate and expand Display adapter.
• Right-click on the display device and click uninstall.

Note: Please restart your computer after performing the steps above.

If the issue persists, download and install latest display driver from the computer manufacturer's website.

Please update us with the status. We will be glad to assist you.
