• Second, view Device Manager found that the independent graphics driver is not installed, when the installation is still not free to adjust brightness.

  You can try to resolve the following scenarios:

• Right-click "Start Menu"--select "Run"--enter "regedit", return to open the registry, and expand in sequence:
