Enabling Lower Minimum Brightness in Windows 10

Sensitive to screen lights and looking for a way to improve the minimum brightness value in Windows 10? This article will guide you through the process of editing the registry to achieve a lower brightness value than the default setting.

Understanding the Concept

The brightness of a screen is determined by the backlight, which is controlled by the graphics driver. By default, Windows 10 has a minimum brightness level that cannot be adjusted beyond a certain point. However, it is possible to edit the registry to lower the minimum brightness value, providing a more comfortable viewing experience for those who are sensitive to screen lights.

   HKEY\_LOCAL\_MACHINE\SYSTEM\ControlSet001\Control\Class\{4d36e968-e325-11ce-bfc1-08002be10318}\0000

   Note: The 0000 at the end of the key may vary depending on the number of display adapters installed on your computer.

4. Right-click on the right-hand side of the window and select New > DWORD (32-bit) Value.
5. Name the new value MinBrightness and set the value to 0.
6. Click OK to save the changes.
