How to Add or Remove "Dim display after" from Power Options in Windows


The Dim display after setting in Power Options allows users to specify how long in minutes your computer is inactive before the display dims. This setting applies only to portable computers (ex: laptop or tablet) that support Windows control of the brightness level of an integrated display device.

If you did not originally have the Dim display after setting available, then it means it is not supported on your computer. Instead, the display will automatically dim by the set Dimmed display brightness percentage exactly 10 seconds before the specified Turn off display after time.

If Dim display after is set to 0 minutes, then the display will not dim.

This tutorial will show you how to add or remove the Dim display after setting under Display in Power Options for all users in Windows 7, Windows 8, and Windows 10.

You must be signed in as an administrator to be able to add or remove this setting in Power Options.
