In this article, we will discuss how to automatically dim the display in Windows when inactive for a longer period. Please make sure that you stay tuned till the end of this article.

How to Automatically Dim the Display in Windows

In this section, we’ll discuss the approach we can take to turn on the dimming display after some inactivity feature in our Windows computer. The latest versions of Windows don’t have the option enabled by default, so we have to perform some tweaks to enable the option at first. Here’s all that’s covered in this section:

1. Windows Terminal
2. Registry Editor
3. Control Panel

Let’s now have a detailed look.

1] Adding The Dim Display After Option In Control Panel Using Windows Terminal

The first method we discuss will guide us to add the Dim display after feature to the Power Options of our Windows PC using the Windows Terminal. Follow the steps listed below:

• Right Click the Start icon and look for the Windows Terminal (Admin) option from the context menu.
• Click on it to open it. Doing so will launch an elevated Windows Terminal. It offers complete computer access and tweaks any setting or component from the command line interface.
• Type the following command:

REG ADD HKLM\SYSTEM\CurrentControlSet\Control\Power\PowerSettings\7516b95f-f776-4464-8c53-06167f40cc99\17aaa29b-8b43-4b94-aafe-35f64daaf1ee /v Attributes /t REG_DWORD /d 2 /f

• Press the Enter key.

This should add the option for dimming the display after some inactivity under the Power Options in Control Panel.

2] Adding The Dim Display After Option In Control Panel Using Registry Editor

Windows Registry Editor, as the name suggests, lets you make changes to your computer in the Windows Registry. Windows Registry is a crucial component where all settings of your Windows computer are saved in the form of values.

Note: Always create a system restore point or backup registry before making any changes using the Registry editor.

Follow the steps listed below to add the feature of Dim display after to the Power Options in Control Panel.

• Press Windows + R key to launch the run dialog box on your computer.
• Type Regedit and hit Enter. This will open the Registry Editor of Windows.
• Navigate to the following location:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Power\PowerSettings\7516b95f-f776-4464-8c53-06167f40cc99\17aaa29b-8b43-4b94-aafe-35f64daaf1ee

• Double-click on the Attributes REG_DWORD value.
• Set the value data to 2 to add the option of Dim display after.

3] Enabling Dim Display After Option In Control Panel

Now that you have enabled the option in Control Panel by following any one of the methods listed above, let’s proceed by accessing the option in Control Panel:

• Open Control Panel by searching for it in the Start menu.
• Once opened, change the View by the filter to Large Icons to reveal all the options. 
• Now Open Power Options.
• You’ll now see a Power Plan. Click on the Change Plan Settings next to it.
• Now on the next screen. Click on the Advanced Power settings option.
• In the Advanced Power Settings, find the Display option and expand it to find the Dim Display After option underneath.

Now you can use the automatic display dim duration according to your convenience.

Conclusion: 

The feature of dimming the display automatically when your device has been inactive for a while is greatly viable and helpful for battery and power perseverance. That said, we’ll wrap this guide up with the hope that it was of aid to you.

What Is The Difference Between Dimming The Display And Adaptive Brightness? How Does It Work?

Windows provides its users with a feature that lets them make changes to the brightness of their display. This feature allows the users to set a period of inactivity, after which the display of their Windows computer will automatically dim (lower the brightness) to preserve the battery to provide longer life, even if it’s not entirely charged.

You can alter it so your Windows device will automatically dim the display after the set time has passed. It can be any number of minutes you input.

Although both settings are about the overall display brightness, you only get to turn adaptive brightness on and off. However, if you’re turning on the Dim display after feature, your computer will dim the brightness only after the set time of inactivity has passed.

While adaptive brightness is subject to change at all moments, dimming the display seems a better option for battery preservation.

How To Enable Windows Adaptive Brightness Feature On Any Windows Computer?

The adaptive brightness feature cannot be enabled on all Windows computers as it requires the light sensor and its necessary modules to function. The option should be under the Display settings if a light sensor is on your computer.
