^{(Dim display after )}在 电源选项 设置中^{(Power Options )}调 暗显示允许用户在特定时间后调暗他们的计算机显示。但是，如果您不希望其他人更改此功能，您可以使用命令提示符^{(Command Prompt)}和注册表编辑器^{(Registry Editor)}从电源选项设置^{(Power Options)}后删除或隐藏暗淡显示^{(Dim display after)}。

如果您使用的是 Windows 11/10 笔记本电脑，那么节省电池可能是您的首要任务之一。为此，Windows 提供了多种功能，其中之一是 在^{(Dim display after)}. 它可以让您在预定义的时间后自动调暗显示亮度（而不是关闭灯）。但是，并非所有Windows笔记本电脑都支持此功能。如果您的计算机支持它，但您不想让其他人弄乱此设置，您可以在 “电源选项” ^{(Power Options )}面板中隐藏它。

有两种方法可以做到这一点——使用命令提示符^{(Command Prompt)}和使用注册表编辑器^{(Registry Editor)}。如果您使用注册表编辑器^{(Registry Editor)}方法，请不要忘记 在继续之前创建一个系统还原点。另一方面，您将使用 powercfg 命令，它可以帮助您 更改或修改电源配置以提高性能^{(change or modify the Power configuration for performance)}。

^{(Hide Dim)}使用命令提示符^{(Command Prompt)}从电源选项中^{(Power Options)}隐藏暗淡显示。

要在Power Options^{(Power Options)}之后显示或隐藏Dim display ，请执行以下步骤：

1. 在任务栏^(Taskbar)搜索框中搜索 cmd 。
2. 单击 以管理员身份运行 ^{(Run as administrator )}选项。
3. 单击 “是”按钮 ^(Yes )。
4. 输入此命令：powercfg -attributes SUB_VIDEO 17aaa29b-8b43-4b94-aafe-35f64daaf1ee +ATTRIB_HIDE

首先，您必须以管理员权限打开命令提示符。^{(Command Prompt)}为此，您可以 在任务栏^(Taskbar)搜索框中搜索 cmd，单击 以 ^(cmd )管理员身份运行 ^{(Run as administrator )}选项，然后单击 是 ^(Yes )按钮。

接下来，输入以下命令以隐藏此选项：

powercfg -attributes SUB_VIDEO 17aaa29b-8b43-4b94-aafe-35f64daaf1ee +ATTRIB_HIDE

如果要在Power Options ^{(Power Options )}面板中重新添加 Dim display after 选项 ，请输入以下命令：

powercfg -attributes SUB_VIDEO 17aaa29b-8b43-4b94-aafe-35f64daaf1ee -ATTRIB_HIDE

之后，您可以检查 “电源选项” ^{(Power Options )}窗口以找出选项。

如何使用注册表编辑器^{(Registry Editor)}从电源选项^{(Power Options)}关闭暗显示^(Dim)

要使用注册表编辑器^{(Registry Editor)}从电源选项^{(Power Options)}打开或关闭暗淡^(Dim)显示，请按照下列步骤操作：

1. 按 Win+R 打开“运行”对话框。
2. 键入 regedit 并点击 Enter 按钮。
3. 单击“是 ”选项 ^(Yes )。
4. 导航到17aaa29b-8b43-4b94-aafe-35f64daaf1eeHKLM。
5. 双击 属性^(Attributes)REG_DWORD 值。
6. 将数值数据设置为1以将其关闭。
7. 单击 “确定” ^(OK )按钮。
8. 重启你的电脑。

让我们详细检查这些步骤。

首先，您必须在计算机上打开注册表编辑器。为此，按 Win+R，键入 regedit，然后 按Enter 按钮。接下来，单击 UAC 提示符上的Yes 选项。

打开注册表编辑器^{(Registry Editor)}后，导航到此路径：

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

在这里您可以找到一个名为Attributes的^(Attributes)REG_DWORD值 。您需要双击它并将值^(Value)数据 设置为1以关闭此功能。

单击 “确定” ^(OK )按钮并重新启动计算机以保存更改。

如果您想再次添加它，请导航到相同的路径，双击相同的REG_DWORD值，然后将值^(Value)数据 输入为2。

为什么我的屏幕一会就变暗了？

默认情况下，Windows 11/10 会在 1 分钟后自动使笔记本电脑的显示屏变暗。如果您的设备支持此功能，您需要检查上述设置以了解可能的更改。

显示屏亮度变暗是什么意思？

某些笔记本电脑具有此功能，可让您设置在预定义的不活动时间后自动关闭的暗显示器的亮度级别。换句话说，您可以在Windows 11/10上选择调暗显示器的亮度级别。

这就是全部！希望本教程有所帮助。

How to show or hide Dim display after from Power Options in Windows

Dim display after in a Power Options setting allows users to dim their computer display after a specific time. However, if you do not like others to change this functionality, you can remove or hide the Dim display after setting from Power Options using Command Prompt and Registry Editor.

If you are using a Windows 11/10 laptop, saving the battery may be one of your priorities. For that, Windows offers several features, and one of them is Dim display after. It lets you dim your display brightness (instead of turning off the light) automatically after a predefined time. However, not all Windows laptops support this feature. If your computer supports it, but you do not want to let others mess with this setting, you can hide it from the Power Options panel.

There are two ways to do that – using Command Prompt and using Registry Editor. If you use the Registry Editor method, don’t forget to create a System Restore point before going forward. On the other hand, you are about to use the powercfg command, which helps you change or modify the Power configuration for performance.

Hide Dim display after from Power Options using Command Prompt.

To show or hide Dim display after from Power Options, follow these steps:

1. Search for cmd in the Taskbar search box.
2. Click on the Run as administrator option.
3. Click the Yes button.
4. Enter this command: powercfg -attributes SUB_VIDEO 17aaa29b-8b43-4b94-aafe-35f64daaf1ee +ATTRIB_HIDE

At first, you have to open Command Prompt with administrator privilege. For that, you can search for cmd in the Taskbar search box, click on the Run as administrator option, and click the Yes button.

Next, enter the command following command to hide this option:

powercfg -attributes SUB_VIDEO 17aaa29b-8b43-4b94-aafe-35f64daaf1ee +ATTRIB_HIDE

If you want to re-add the Dim display after option in the Power Options panel, enter the following command:

powercfg -attributes SUB_VIDEO 17aaa29b-8b43-4b94-aafe-35f64daaf1ee -ATTRIB_HIDE

After that, you can check the Power Options window to find out the option.

How to turn off Dim display after from Power Options using Registry Editor

To turn on or off Dim display after from Power Options using Registry Editor, follow these steps:

1. Press Win+R to open the Run dialog.
2. Type regedit and hit the Enter button.
3. Click on the Yes option.
4. Navigate to 17aaa29b-8b43-4b94-aafe-35f64daaf1ee in HKLM.
5. Double-click on the Attributes REG_DWORD value.
6. Set the Value data as 1 to turn it off.
7. Click the OK button.
8. Restart your computer.

Let’s check out these steps in detail.

At first, you have to open the Registry Editor on your computer. For that, press Win+R, type regedit, and hit the Enter button. Next, click on the Yes option on the UAC prompt.

After opening the Registry Editor, navigate to this path:

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

Here you can find a REG_DWORD value named Attributes. You need to double-click on it and set the Value data as 1 to turn off this feature.

Click the OK button and restart your computer to save the change.

If you want to add it again, navigate to the same path, double-click on the same REG_DWORD value, and enter the Value data as 2.

Why does my screen go dim after a while?

By default, Windows 11/10 dims the laptop’s display automatically after 1 minute. If your device supports this functionality, you need to check the aforementioned setting for possible changes.

What does dimmed display brightness mean?

Some laptops come with this feature, which lets you set the brightness level of the dimmed display that goes off automatically after a predefined time of inactivity. In other words, you can select the brightness level of your dimmed display on Windows 11/10.

That’s all! Hope this tutorial helped.
