Windows 10 Lock Screen Dimming : Fix

Recently, several users of Windows 10 complaint about a strange issue, which is causing the Windows 10 lock screen go dimmer. There was no such setting in Windows 10 which could do it so it was completely strange that why is it happening. So after a lot of research and tests, I finally found the real cause of the issue.

The problem persists only in Lenovo devices and it is happening because of an "Enhancement" which its OEM software is applying to the device. Follow these steps to fix the issue:

• Open Lenovo Vantage software which is pre-installed in your Lenovo device.
• Click on "Hardware Settings".
• Click on "Audio/Visual" and then turn off "Enable Dynamic Brightness Control".

That's it. The issue would be resolved and you would no longer notice dimming of lock screen wallpaper.
